Accelerate your high-volume fastening schedules inside dense equipment cabinets, joist spaces, and structural assemblies with the Milwaukee® M18™ Compact Brushless 1/4" Hex Impact Driver. Specifically engineered to close the physical gap between heavy subcompact frameworks and standard full-size trade tools, this cordless impact driver measures an ultra-short 4.4 inches in length and just 2.1 inches in width. Driven by a premium brushless motor, it maximizes battery energy transfer to deliver a staggering 1,700 in-lbs of fastening force and a blistering top speed of 3,600 RPM, preventing motor stall when driving self-tapping sheet metal screws or long structural timber fasteners. To ensure professional-grade precision on the job site, the impact tool is equipped with an enhanced variable speed trigger that allows operators to carefully feather power output, drastically reducing the risk of stripped heads, fractured bits, or marred work surfaces. The robust internal drivetrain is constructed with an all-metal gearcase and premium solid gears to handle severe rotational abuse day after day. Monitored by advanced REDLINK™ Intelligence system communication to optimize power draws and safeguard against destructive thermal cleanouts, this bare tool (3650-20) offers a lightweight 1.7 lb bare footprint that integrates flawlessly into the trade-trusted M18™ battery platform.
