Milwaukee M18 FUEL 4-1/2" / 6" Braking Grinder Slide Switch M18 3671-20
CORDED PERFORMANCE WITHOUT THE CORD: THE ULTIMATE 6-INCH GRINDING SOLUTION
The 3671-20 represents a massive leap in cordless metalworking, delivering the raw 13A power traditionally reserved for corded industrial units. Engineered around the POWERSTATE™ Brushless Motor, this grinder maintains a consistent 9,000 RPM under heavy load, ensuring that productivity doesn't dip when the material gets tough. The integration of REDLINK PLUS™ Intelligence provides a sophisticated communication link between the tool and battery, optimizing performance while shielding the motor from the thermal stresses of continuous grinding and cutting. For the professional looking to maximize ROI, the mechanical durability and advanced safety features like the RAPIDSTOP™ brake make this a staple for high-volume jobsites.
- / RAPIDSTOP™ Braking System stops abrasive wheels in under 2 seconds, allowing for faster tool set-downs and improved jobsite safety.
- / 13A Corded Power equivalent ensures you can tackle the most aggressive grinding and cutting applications without the hazard of trailing cables.
- / Electronic Clutch and Kickback Protection actively monitor motor torque to prevent tool bind-ups and protect the drivetrain.
- / 6-Inch Disc Capacity provides a wider range of cutting depths and grinding surface area compared to standard 4-1/2" models.
- / Anti-Vibration Side Handle and streamlined grip design reduce user fatigue during extended operation in heavy-duty environments.
