For a cordless drill bit set that balances coverage with useful drilling features, I’d start with the DEWALT 21-Piece DWA1181: its 135-degree split points, black oxide coating, and broad everyday size range make it the strongest general-purpose drilling pick here. If you need drilling and driving accessories in one case, the Amazon Basics 100-Piece Set offers a more varied assortment; for quick bit changes, the COMOWARE 16-Piece Hex-Shank Set has a useful compact format.

The main tradeoff is focused drill-bit performance versus accessory variety. The DEWALT sets concentrate on drilling, while Amazon Basics and KingTool add driver bits and other attachments that may save a second purchase but make the contents less focused. I’ve ranked these options by how clearly their bits suit cordless-drill work, the usefulness of their range, and how easy their limitations are to judge from the supplied specifications. None is presented as a specialist solution for hardened metal, and buyers should check chuck compatibility and the listed contents before choosing.

More Details on Our Top Picks
DEWALT 21-Piece High Speed Steel Drill Bit Set (DWA1181)
I rank the DEWALT DWA1181 first because it is the most clearly specified drilling-focused set in this group. Its 21 high-speed steel bits are intended for metal, hardwood, softwood, PVC, and fiberglass, giving a household or workshop buyer a more useful spread than the smaller DEWALT 14-piece set. The 135-degree split point is designed to reduce walking as a hole starts, while the 31-degree helix and parabolic flutes are intended to help carry chips out of the cut.
Those details matter when a cordless drill is being used across different materials: a bit that starts more steadily can be easier to control, and chip removal can help keep a hole from clogging during drilling. The black oxide coating is described as helping resist corrosion and support durability. Compared with the COMOWARE set, this one emphasizes a broader range of drill sizes and flute design rather than a quick-change hex shank. Compared with the DEWALT 14-piece set, it gives buyers more size coverage, though the two share split-point drilling features.
The boundaries are clear. These are high-speed steel bits, not cobalt bits, so I would not choose this set on the expectation of repeated drilling into hardened steel. The plastic case may also be less reassuring for rough job-site handling than a more rugged storage solution. Still, for the broadest straightforward drilling role in this particular lineup, the combination of 21 pieces, multiple stated materials, and useful tip and flute details makes it my lead pick.
Pros:- 21-piece assortment covers more common sizes than the 14-piece DEWALT set
- 135-degree split points are designed to reduce bit walking
- Parabolic flutes and a 31-degree helix support chip ejection
- Intended for metal, hardwood, softwood, PVC, and fiberglass
Cons:- High-speed steel is not the specialist choice for hardened-metal work
- Plastic case may be less robust than metal storage for rough job-site use
Best for: Homeowners and workshop users who want a drilling-focused assortment for common jobs in wood, plastic, PVC, fiberglass, and ordinary metal.
Not ideal for: Buyers who regularly drill hardened metals, need a driver-bit collection, or prioritize a heavy-duty metal storage case.
- Brand:DEWALT
- Model:DWA1181
- Piece count:21
- Material:High-speed steel
- Coating:Black oxide
- Tip angle:135 degrees
- Helix angle:31 degrees
- Flute design:Parabolic
- Compatible materials:Metal, hardwood, softwood, PVC, and fiberglass
Our verdict“For buyers who want one clearly specified set of general-purpose drill bits, the DWA1181 offers the best balance of size coverage and drilling features in this lineup.”
DEWALT 14-Piece Drill Bit Set with 3-Flat Shank
For a buyer who wants fewer, drilling-specific bits, this 14-piece DEWALT set is a more compact alternative to the DWA1181. It is made from high-speed steel for plastic, wood, and metal, and its 135-degree split-point tips are designed to start with less wandering. The tapered web is intended to help resist breakage, while the black-and-gold coating supports wear and rust resistance.
The distinguishing detail is its 3-flat shank. Flats can help reduce spin-out in a compatible chuck, but the product description limits that benefit to sizes larger than 3/16 inch. That qualification makes the shank feature less universal than a quick glance at the title might suggest. Compared with COMOWARE’s 1/4-inch hex shanks, this design is aimed at a drill chuck rather than quick-change convenience; compared with the 21-piece DEWALT, it gives up size breadth in exchange for a smaller, more focused assortment.
I’d choose it when the planned jobs fit its three stated material categories and a modest number of drill sizes is enough. It is not the best choice for someone who wants to cover a wider range without adding bits, or who needs driver accessories in the same case. The provided details do not state an exact size range, so I would check the included sizes before buying rather than assume it overlaps perfectly with an existing kit. Its split-point tips and chuck-oriented shank are useful distinctions, but they do not make it a substitute for a broader or specialist set.
Pros:- 135-degree split-point tips are designed to reduce walking
- Tapered web is intended to help resist breakage
- Black-and-gold coating supports wear and rust resistance
- Made for plastic, wood, and metal drilling
Cons:- 14 pieces provide less size coverage than the DWA1181
- The stated spin-out benefit applies only to sizes larger than 3/16 inch
- Exact bit size range is not provided in the supplied specifications
Best for: DIYers who want a smaller drilling-only kit for common plastic, wood, and metal work and whose drill uses a compatible chuck.
Not ideal for: Buyers who need the broadest size selection, quick-change hex shanks, or a combined drill-and-driver assortment.
- Brand:DEWALT
- Model:DWA1184
- Piece count:14
- Material:High-speed steel
- Shank:3-flat
- Tip design:135-degree split point
- Coating:Black and gold
- Suitable materials:Plastic, wood, and metal
Our verdict“Choose this DEWALT when a compact, drilling-focused kit matters more than the wider size coverage of its 21-piece sibling.”
COMOWARE Titanium-Coated Twist Drill Bit Set, 16-Piece, 1/16–1/4 in., Hex Shank
The COMOWARE set earns its place through 1/4-inch hex shanks, which suit quick-change chucks and can make swapping between compatible accessories more convenient than using ordinary round-shank bits. Its stated 1/16-to-1/4-inch range covers small, common drilling tasks, and the indexed holder gives each bit a marked place. For a home DIY kit that gets stored between jobs, that organization can make the assortment easier to return to and find again.
The bits use hardened high-speed steel with a titanium coating and a two-flute design described as helping clear chips and reduce heat. Those features give it a different emphasis from the DEWALT DWA1181: DEWALT supplies more pieces and spells out several compatible materials and flute details, while COMOWARE is more compelling when shank format and compact storage matter. Its general-use description covers metal, wood, and plastic, but it does not provide specialized performance claims that would justify choosing it for demanding material-specific work.
There is one unusually practical caveat: the product title says 16 pieces, while product details list 13. I would verify the actual pack contents before ordering, especially if exact bit coverage is the reason for choosing it. The stated size range is useful, but the set may be less suitable for users whose drill cannot accept 1/4-inch hex shanks or who want a detailed, broad size assortment. Its best case is a cordless drill setup built around quick bit changes, not maximum bit count.
Pros:- 1/4-inch hex shanks fit compatible quick-change chucks
- Hardened high-speed steel bits have a titanium coating
- Two-flute design is intended to clear chips and reduce heat
- Indexed holder helps keep bits organized
Cons:- Piece count conflicts: title says 16, while product details list 13
- General-use positioning offers no specialized performance claims
- Hex shanks require a compatible chuck or adapter
Best for: DIY users with a compatible quick-change chuck who want a compact set of small-to-medium general-purpose bits and an indexed holder.
Not ideal for: Buyers who need a confirmed piece count, a wide selection beyond 1/16–1/4 inch, or specialized bits for demanding materials.
- Brand:COMOWARE
- Model:TGHEXSHANK
- Listed set size:16 pieces in title; product details also list 13
- Bit size range:1/16–1/4 inch
- Material:High-speed steel
- Coating:Titanium
- Flutes:2
- Shank:1/4-inch hex
- Included:Indexed storage holder
Our verdict“This is the most convenient pick for compatible quick-change setups, provided the buyer confirms the listed contents before purchase.”
Amazon Basics 100-Piece Drill and Driver Bit Set
The Amazon Basics set is the lineup’s most practical option for someone who wants to handle drilling and fastening from one case. Its 100 pieces include drill bits, screwdriver bits, nut drivers, hole saws, a magnetic bit holder, and other accessories. That mix can reduce the need to keep a separate driver-bit kit nearby. The plastic storage case is intended to keep the pieces together for transport and storage.
Compared with the DEWALT DWA1181, this is less of a focused drilling purchase: the DWA1181 has clearly described split-point tips and flute geometry, while this set’s main advantage is category breadth. The description lists use in metal, wood, plastic, and masonry, but does not supply the same bit-specific tip and shank information as the two DEWALT sets. Its wear-resistant alloy steel construction is described at a broad level, so I would not infer specialist performance for any particular material from that wording alone.
The drawback is that 100 pieces are only useful if you can identify the pieces you need. The full included list may be difficult to scan, which makes it harder to confirm whether the assortment contains a particular size or accessory before purchase. For a new homeowner or occasional repair user, the varied selection may be more useful than a focused 14- or 21-bit drill set. For someone who already owns driver bits and wants dependable, clearly specified drilling features, the DWA1181 is easier to evaluate and a better match.
Pros:- 100-piece assortment combines drilling and driving accessories
- Includes nut drivers, hole saws, and a magnetic bit holder
- Described for use in metal, wood, plastic, and masonry
- Plastic case supports organization and transport
Cons:- Full list of included pieces may be difficult to scan
- Less detail is provided about individual drill-bit designs and sizes
- Broad accessory mix is less focused than the DEWALT drill-bit sets
Best for: Homeowners and general DIY users who want drill bits, driving accessories, nut drivers, and hole saws stored together.
Not ideal for: Buyers seeking a clearly documented, drill-bit-only assortment or exact bit-by-bit size details before choosing.
- Brand:Amazon Basics
- Model number:DS-DB100
- Piece count:100
- Material:Alloy steel
- Included:Drill bits, screwdriver bits, nut drivers, hole saws, magnetic bit holder, and accessories
- Case:Plastic storage case
- Item weight:4 pounds
- Stated materials:Metal, wood, plastic, and masonry
Our verdict“Pick this set when accessory variety matters more than detailed specifications for a focused collection of drill bits.”
KingTool 318-Piece Screwdriver and Drill Bit Set
KingTool is the broadest kit here, with 318 pieces spanning drilling and driving tasks. The stated assortment includes high-speed steel drill bits, masonry and wood bits, Allen wrenches, and screwdriver bits made from chromium-vanadium steel. Coded bits are intended to make identification quicker, and the moisture-resistant case gives the many pieces a designated place. For someone setting up a varied household toolkit, that all-in-one approach can be more useful than adding a focused drill-bit set and separate fastening accessories.
Its breadth distinguishes it from Amazon Basics’ 100-piece mixed kit, and especially from the DEWALT options, which are more explicitly centered on drilling. KingTool names several bit categories and materials, but the supplied information does not lay out an exact size range or explain the individual drill-bit tip designs. That makes it harder to judge whether it contains the particular sizes or specialized geometry a project calls for. Coded pieces may help with recognition, but they do not replace a readable inventory.
The large count comes with a real organizational cost. 318 pieces can be excessive for casual users who need only a few standard drill bits, and the plastic case, despite its moisture-resistant description, may not suit rough job-site handling as well as a tougher storage system. Its weight and case dimensions also make it a less minimal choice than COMOWARE’s compact indexed holder. I’d choose it for assortment breadth across drilling and driving—not because the listed piece count alone proves that its drill bits outperform the more focused DEWALT sets.
Pros:- 318-piece assortment spans drilling and fastening categories
- Includes high-speed steel, masonry, and wood bits plus Cr-V driver bits
- Coded bits are intended to aid identification
- Moisture-resistant case provides organized storage
Cons:- Large assortment may overwhelm users with simple drilling needs
- Supplied details do not list exact drill-bit sizes or tip designs
- Plastic case may be less suitable for rough job-site handling
Best for: DIYers building a varied home toolkit who want drill, masonry, wood, and driver accessories organized in one case.
Not ideal for: Casual users who need only a handful of drill bits, buyers needing exact bit sizes upfront, or workers seeking a rugged job-site case.
- Brand:KingTool
- Model:DSP-DB318
- Piece count:318
- Materials:Chromium-vanadium steel, plastic, and high-speed steel for drill bits
- Shank type:Hex
- Finish:Corrosion resistant
- Item weight:5.94 pounds
- Case dimensions:11.8 x 8.8 x 2 inches
- Included categories:Drill, masonry, wood, Allen wrench, and screwdriver bits
Our verdict“KingTool makes sense when a single organized kit for many drilling and driving tasks matters more than a focused, precisely documented drill-bit range.”
How We Picked
I compared these five sets as accessories for a cordless drill or driver, rather than treating piece count as a shortcut for quality. I gave more weight to the details that affect ordinary drilling: bit material and coating, tip design, flute geometry, shank style, stated material compatibility, and whether the assortment appears focused enough to use without sorting through many unrelated accessories.
The DEWALT DWA1181 ranks first because the supplied specifications connect its 21-bit range to clear drilling features and several intended materials. The 14-piece DEWALT set follows as a more compact drilling-focused alternative, while COMOWARE earns a distinct place for its hex shank and quick-change convenience. I placed Amazon Basics and KingTool below those focused sets because their broad drill-and-driver contents can be valuable, but the descriptions do not give the same level of bit-specific detail.
I also considered limits, not just advantages. High-speed steel is a general-purpose choice, not a claim of suitability for demanding hardened-metal drilling. Shank style matters only if it matches the user’s chuck and work habits, and a large assortment is useful only when its contents are legible and accessible. Where product details conflict—such as COMOWARE’s stated 16-piece title versus a 13-piece listing—I call that out rather than treating the specification as settled.
This ranking is based on the supplied product descriptions and specifications. It does not imply hands-on testing or claim that any set outlasts another under identical conditions. I favor clear fit, relevant features, and honest tradeoffs so readers can match a set to the jobs they actually expect to do.

Factors to Consider When Choosing Best Cordless Drill Bit Set
Before choosing a set, I’d match its shank, range, and bit design to the drill and materials already in my toolkit. A high piece count cannot make up for missing sizes or a shank that does not fit your chuck, and a mixed accessory kit should be judged differently from a drill-bit-only set.
Check the shank against your drill
The COMOWARE set specifies 1/4-inch hex shanks, a useful format for compatible quick-change chucks and adapters. The DEWALT 14-piece set uses a 3-flat shank, with its described anti-spin benefit limited to sizes larger than 3/16 inch. The DWA1181 details supplied here do not state a shank style, so check the product listing if that detail affects your drill. A cordless drill with a standard chuck may accept several shank shapes, but a quick-change holder may narrow compatibility. Match the bit to the chuck rather than assuming every drill-bit set mounts the same way.
Choose focused bits or a mixed accessory case
The DEWALT sets concentrate on drilling, making their bit-specific features easier to compare. Amazon Basics and KingTool combine drill bits with screwdriver bits and other accessories, which can be convenient if you are assembling a starter kit or switching between pilot holes and fasteners. That variety also means more pieces to identify and store. If you already own a driver-bit set, a focused drill assortment may give you more relevant coverage; if not, a mixed case could reduce the number of separate kits you need.
Read material and coating claims carefully
High-speed steel appears in the DEWALT and COMOWARE descriptions and serves as a general-purpose material for the stated everyday applications. COMOWARE adds a titanium coating; the DEWALT DWA1181 uses black oxide, and the 14-piece set has a black-and-gold coating. These are different product details, not proof of identical performance. For frequent work in hardened metals, none of the supplied descriptions establishes a specialist cobalt specification, so I would look for a dedicated set intended for that use instead of stretching a general-purpose kit beyond its stated role.
Think about starting accuracy and chip removal
A split-point tip, as specified on both DEWALT sets, is designed to reduce walking when a hole starts. That can help when the bit needs to begin on a hard or smooth surface. The DWA1181 also calls out a 31-degree helix and parabolic flutes to support chip ejection; COMOWARE describes a two-flute design intended to clear chips and reduce heat. Those details may matter more for repeated drilling than the number of unrelated accessories in a case, but the right choice still depends on the task and material.
Verify sizes, piece counts, and storage
Check the actual bit-size list before choosing a set, especially if you need to match existing fasteners, plugs, or a project plan. COMOWARE has a stated range of 1/16–1/4 inch, but its advertised piece count conflicts with another supplied listing. The DEWALT 14-piece information does not provide an exact range, while the Amazon Basics and KingTool descriptions do not list every drill-bit size. Storage is part of everyday use too: an indexed holder or organized case can help return bits to the right place, while a large assortment may be cumbersome if you only reach for a few sizes.
Frequently Asked Questions
Which set is the best general-purpose choice for a cordless drill?
I’d start with the DEWALT DWA1181 for broad everyday drilling. It has 21 high-speed steel bits, 135-degree split points, and stated compatibility with metal, hardwood, softwood, PVC, and fiberglass. It is a general-purpose choice, not a specialist set for hardened metals, and its plastic case may not suit rough handling.
Are hex-shank drill bits compatible with every cordless drill?
No. Check your chuck or bit holder before choosing a shank style. COMOWARE specifies 1/4-inch hex shanks for compatible quick-change chucks, while the DEWALT 14-piece set lists a 3-flat shank. A standard drill chuck may accept a range of shanks, but quick-change systems and adapters can affect fit.
Should I choose more pieces or a focused drill-bit set?
Choose by the work you expect to do, not by the count alone. The DEWALT sets focus on drilling and provide clearer drill-bit features, while Amazon Basics and KingTool add driver accessories and other tools. If you need one case for varied repair tasks, those mixed kits may be convenient; if you want specific drill sizes and features, a focused set is easier to evaluate.
Which set is best for drilling hardened metal?
None of the supplied descriptions establishes these as specialist hardened-metal sets. The DEWALT and COMOWARE options are described as high-speed steel, and the broader kits do not provide enough detail to confirm a dedicated hardened-metal design. For repeated work in hard alloys, I’d look for a set explicitly specified for that material and follow the bit maker’s drilling guidance.
What should I check before buying the COMOWARE set?
Confirm both chuck compatibility and package contents. The set uses 1/4-inch hex shanks, which suit compatible quick-change holders, and its stated size range is 1/16–1/4 inch. The title lists 16 pieces while product details also list 13, so verify the current contents if the exact number of bits matters to your choice.
Conclusion
For most buyers who want one general-purpose drilling set, I recommend the DEWALT DWA1181: its size count and stated bit features give it the clearest all-around case. Choose the DEWALT 14-piece set if you want a smaller drill-only assortment, or COMOWARE if your setup favors a compatible quick-change chuck and its size range fits your work. For homeowners who want driving accessories alongside drill bits, Amazon Basics is the more manageable mixed-kit alternative; for the buyer assembling a much broader accessory collection, KingTool offers the widest variety, with more pieces to organize. Before ordering, match the shank to your drill, check the actual bit sizes, and treat general-purpose high-speed steel as distinct from a specialist hardened-metal solution.
