Details
The Milwaukee M18 FUEL 4-1/2" – 6" Braking Grinder (model 3670-20) is a cordless angle grinder with a paddle switch and no lock-off, built on the M18 battery system. It runs a POWERSTATE brushless motor that spins to 9,000 RPM and generates the equivalent of 13A corded power, delivering up to 135 cuts per charge. This is a bare tool — the M18 battery and charger are sold separately.
What it does well
- POWERSTATE brushless motor reaches 9,000 RPM for grinding and cutting through the toughest material.
- RAPIDSTOP brake stops most wheels in under 2 seconds when the paddle is released.
- Electronic clutch guards against kickback, and overload protection helps maximize motor life.
- REDLINK PLUS intelligence manages performance, protection, and battery-to-tool communication.
Is this the right grinder for you?
Choose the 3670-20 if you already own M18 batteries and want a full-size, cordless grinder that handles both 4-1/2" and 6" wheels. The paddle switch and RAPIDSTOP brake suit pros who value control and quick wheel stops. Because it ships as a bare tool, pick this version to save money when you have batteries on hand; if you need power included, look for a kit instead.
