Backing Flange For 2880-20 43-34-3000

Milwaukee's genuine OEM Backing Flange (also known as an Inner Flange) specifically designed for the M18 FUEL™ 4-1/2" / 5" Braking Grinder (2880-20). This precision-engineered component sits directly on the spindle and provides the necessary flat, stable surface for grinding wheels and flap discs to seat against. Because the 2880-20 features a rapid-stop braking system, this flange is designed to maintain a high-friction connection to the spindle, ensuring the accessory stops safely and instantly when the trigger is released.
Key Features
Braking System Compatible: Specially keyed or surfaced to work with Milwaukee's RAPIDSTOP™ brake, preventing the flange from spinning loose during sudden deceleration.
High-Strength Steel: Machined from hardened steel to resist warping and wear under the high-torque conditions of a brushless motor.
Precision Alignment: Ensures the grinding accessory is perfectly centered on the 5/8"-11 spindle to eliminate vibration and "chatter" during use.
Debris Resistance: Designed to sit flush against the gear case to minimize the amount of metal dust and grit entering the spindle seal area.
Direct OEM Fit: Guaranteed compatibility with the 2880-20 and 2881-20 M18 FUEL™ grinder models.
