4-1/2″ Flap Disc, Zirconia, Type 29 (Beveled) with 7/8″ Arbor Hole

This product is a 4-1/2-inch diameter Type 29 (beveled-style) flap disc designed for grinding, weld blending, and contouring on metal surfaces. It features premium zirconia abrasive flaps, bonded with resin adhesive onto a durable fiberglass backing plate. The Type 29 beveled design allows for steeper grinding angles, increasing surface contact for faster material removal and efficient blending, particularly on curved surfaces and edges. The overlapping flap design ensures continuous exposure of fresh abrasive, enabling consistent grinding and cooler cutting throughout the disc’s lifespan. This disc features a 7/8″ arbor hole, designed for use on compatible right-angle grinders, requiring a separate locking nut for secure mounting.
