Milwaukee 2889-20 M18 FUEL 4-1/2″ – 5″ Braking Grinder with Slide Switch Lock-On – Tool Only

POWERSTATE™ Industrial Brushless Motor. RAPIDSTOP™ Safety Braking System. Continuous Action Lock-On Slide Switch.

The Milwaukee 2889-20 M18 FUEL 4-1/2" – 5" Braking Grinder brings blistering raw cutting speed, advanced elite user protection, and untethered cordless mobility directly to your heavy fabrication bay, structural jobsite layout, or field welding bench. Purpose-built to eliminate the frustrating power drops common with brushed angle grinders, the slow rundown times that delay tool storage, and the hand cramps caused by holding down a constant paddle safety trigger during long runs, this premium professional cordless grinder defines an absolute industrial standard. It arms structural ironworkers, industrial pipe welders, demolition crews, and mechanical fabricators with a high-torque material removal asset explicitly optimized to slice thick structural steel, grind down rough weld beads, bevel heavy pipe schedules, and plunge through masonry blocks cleanly.

Engineered for extreme performance and unyielding structural safety, the mechanics of the 2889-20 are driven by Milwaukee’s legendary POWERSTATE™ brushless motor. Spinning at a blistering 8,500 RPM, this grinder matches the cutting force of a corded 11-amp tool while operating entirely on the M18™ lithium-ion battery system. For extended comfort during tedious surface prep work, the body features a lock-on slide switch that keeps the tool running smoothly without keeping constant grip pressure on the trigger. Safety is prioritized through an integrated RAPIDSTOP™ brake that halts cutting discs in under two seconds, paired with Kickback Reduction electronics to prevent violent tool jumps if a blade binds. Tool-free accessory changes are fast and easy via the FIXTEC nut interface and a manual tool-free guard adjustment ring.

Why the Milwaukee® M18 FUEL™ 2889-20 Braking Grinder Rules the Fab Bench:

• Corded Power Without the Cord: High-efficiency brushless system delivers unwavering 8,500 RPM tracking force to replicate corded 11-amp metalworking tools.
• Continuous Lock-On Slide Switch: Maximizes working comfort during tedious surface cleaning or rust removal runs by eliminating finger fatigue.
• Under 2-Second RAPIDSTOP™ Brake: Active safety clutch stops cutting wheels, abrasive discs, or wire wheels in under 2 seconds to safeguard the operator.
• Smart Kickback Mitigation: Internal electronic brake monitors load changes to instantly cut motor power if the wheel locks up or binds in a tight groove.
• 100% Tool-Free Blade Swaps: Includes a premium FIXTEC arbor nut to lock down cutting discs tightly by hand, entirely removing the need for a spanner wrench.
