Product Overview
Engineered for heavy-duty fastening and precision control, the PB428-40 Cordless Brushless Impact Wrench combines industrial torque with intelligent 3-speed regulation. Powered by a 550W high-efficiency brushless motor, it delivers 430N.m fastening torque and a massive 550N.m max breakaway torque. The electronic 3-gear system adjusts speed (1800/2000/2600 RPM) and impact rate (1600/1800/2200 BPM) to match exact job requirements. With a 1/2″ square drive and 8-19mm socket compatibility, it is the ideal choice for scaffolding construction and car lug nut removal. Built for global distributors, contractors, and B2B buyers seeking reliable OEM/ODM cordless fastening solutions.
