Milwaukee Paddle Trigger Assembly Kit, Black
Model Number: 31-92-0010
The Milwaukee 31-92-0010 Paddle Trigger Assembly Kit (Black) is a genuine OEM replacement service kit designed for the Milwaukee 3670-20 M18 FUEL 4-1/2 in. / 6 in. Braking Grinder with Paddle Switch (No-Lock), Milwaukee's flagship cordless braking grinder built for metal fabricators, ironworkers, structural welders, mechanical contractors, automotive service techs, and any tradesperson who needs serious cordless grinding and cutting capacity in a tool with safety-grade braking performance. The paddle trigger assembly is the operator-facing paddle switch mechanism that the user squeezes against the grip to start the grinder, and releases to instantly engage the RAPIDSTOP brake that brings the wheel to a complete stop in under 2 seconds. The No-Lock design is the defining safety feature of the 3670-20 platform: unlike conventional grinders with a lock-on trigger that the operator can release for free-running operation, the 3670-20 paddle requires continuous operator pressure to keep the wheel spinning, so any loss of grip during a kickback, slip, or fall instantly triggers the brake and stops the wheel before it can cause injury.
A worn, cracked, broken, sticking, or seized paddle trigger assembly is a serious safety issue, not just an inconvenience. Symptoms include the paddle sticking in the on position (which defeats the entire purpose of the no-lock safety design), the paddle failing to fully release the trigger mechanism (which prevents the RAPIDSTOP brake from engaging), inconsistent trigger response, or the paddle binding against the grinder housing. Replacing the assembly with this OEM service kit restores correct paddle action, full trigger release, and proper engagement of the RAPIDSTOP brake system the 3670-20 is engineered around. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee 3670-20 service parts diagram before ordering, since Milwaukee uses several different paddle trigger assembly part numbers across their grinder lineup (including 31-92-0210 for the 6142-31 corded angle grinder, and 31-92-1060 for the 2880-20 M18 FUEL Small Angle Grinder) and the 31-92-0010 is specific to the 3670-20 braking grinder platform. Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment.
