Milwaukee’s upcoming M18 Fuel 3962 is rated for 800 ft-lbs of fastening torque and 950 ft-lbs of breakaway torque, in a 6.1-inch head. Pro Tool Reviews reported the specifications after SEMA 2026, but the wrench has not yet undergone independent testing and is expected to launch in the second quarter of 2027.
Milwaukee is preparing to release the M18 Fuel 3962 1/2-inch impact wrench, a new cordless tool rated at 800 ft-lbs of fastening torque and 950 ft-lbs of breakaway torque. Pro Tool Reviews reported the specifications after SEMA 2026; the publication says the wrench is expected to launch in the second quarter of 2027, with hands-on testing still pending.
The 3962 uses Milwaukee’s PowerState brushless motor and has a 1/2-inch square drive with a friction ring. A pin-detent version is listed as model 3962P. The tool measures 6.1 inches long and weighs 4.0 pounds without a battery; Pro Tool Reviews lists its weight with a 5.0Ah battery at 5.7 pounds. Milwaukee has not yet provided a price, speed or impact-rate figure in the information cited by the report.
Listed controls include four-mode drive control, a bolt-removal mode that starts with high power and then slows for removal, and an auto-shutoff mode capped at 50 ft-lbs to limit overtightening. The design also includes three LEDs around the square drive and a battery-isolation system intended to reduce vibration reaching the battery and keep its connection secure. These are manufacturer specifications and feature descriptions, not findings from independent testing.
Pro Tool Reviews compares the claimed torque with Milwaukee’s current 2962, rated at 550 ft-lbs fastening and 650 ft-lbs breakaway. The new model’s listed breakaway figure is 300 ft-lbs higher. The report also compares the 3962 with the DeWalt DCF891, rated at 600 and 800 ft-lbs, and the Makita GWT07, rated at 560 and 810 ft-lbs, respectively. Those comparisons are based on published specifications, not a completed head-to-head test of the 3962.
More Torque in a Compact Body
The listed combination of high torque and a 6.1-inch head could matter to mechanics and other users who need power in confined spaces. Pro Tool Reviews says the 3962 is shorter than the compared DeWalt and Makita models, while offering higher published torque figures. If independent testing supports those ratings, the tool could narrow the practical gap between mid-size impact wrenches and larger, higher-torque models.
For buyers, the figures are a reason to watch the launch, not yet a basis for judging real-world speed or value. Fastener removal and installation depend on more than peak torque, including speed, control settings, battery choice and the fastener itself. Milwaukee has not announced pricing, and the report does not provide test results for runtime, removal speed or sustained performance.

How the 3962 Compares
The 3962 is positioned as a successor to Milwaukee’s M18 Fuel 2962, which Pro Tool Reviews says has been on the market for about five years. On the published figures, the 3962 raises fastening torque from 550 to 800 ft-lbs and breakaway torque from 650 to 950 ft-lbs. Its head is listed as 0.1 inch longer than the 2962, and its bare weight is 0.1 pound greater.
Among the comparison tools cited, the 3962 has the highest stated torque figures. But the report says its speed and impacts-per-minute ratings remain unknown. The 2962 reached up to 2,575 rpm and 3,100 impacts per minute, while the listed DeWalt and Makita models have published maximum speeds of 2,000 and 2,300 rpm. Pro Tool Reviews notes that speed could affect how quickly tools complete fastening or removal tasks, so the torque table alone cannot establish which model performs best overall.
“Milwaukee is claiming up to 60% faster removal speeds than the previous model.”
— Pro Tool Reviews
Testing and Pricing Remain Pending
The 3962’s listed torque figures have not been verified in Pro Tool Reviews’ hands-on tests, and the publication says it does not yet have a tool for head-to-head testing. Its speed and impact-rate figures, retail price and exact availability date have not been provided in the cited report. It is also unclear which battery will provide the best balance of weight and performance; the publication says it may test the tool with an 8.0Ah Forge battery, while the listed kit weight uses a 5.0Ah pack.
The report describes Milwaukee’s claim of up to 60% faster removal than the previous model, but does not specify the test conditions or publish independent results supporting it. The eventual performance of the 3962 against competitors therefore remains to be established.
Launch and Testing in 2027
Milwaukee’s expected launch window is Q2 2027; a firm release date and price have not been reported. Pro Tool Reviews says it plans to conduct testing once it can obtain the wrench, including comparisons with other tools in the class and checks of battery balance. Those results should clarify whether the published torque ratings translate into faster or more capable work in practical use.
