Product Details

The 3M™ flap disc 577F tackles the toughest high-pressure metalworking applications and leaves a blended finish, all in one step. Ideal for a wide range of applications, including weld grinding, deburring, rust removal, edge grinding, and weld seam blending. Fast-cutting alumina zirconia mineral is designed for tough grinding applications where final finish is important.

• Overlapping construction allows more abrasive material to be loaded onto the cutting surface, far outlasting typical discs
• A flap disc easily follows curves and contours
• Flap combines grinding and blending into one step for time savings
• Grinding aid reduces temperatures for heat-sensitive alloys like stainless steel, nickel alloys, and titanium
• Heavyweight polyester-backed flap for longer life
• Quick-change disc simplifies disc changes
