Norton 66254420013 Powerflex Flap Disc 80 Grit Type 29

Product Description

The NORTON 66254420013 is a Powerflex Type 29 flap disc designed for aggressive material removal and blending on metal surfaces. Measuring 7 inches in diameter with a 5/8-11 arbor thread, this disc delivers consistent stock removal across its full face. The 80-grit abrasive grade makes it well suited for weld blending, surface preparation, and deburring on steel and stainless steel. The Type 29 conical profile positions the abrasive at an angle to the workpiece, increasing contact area and cutting efficiency compared to a flat Type 27 disc. Metal fabricators, welders, and maintenance techs are the primary users of this product.

This flap disc is used in industrial and commercial fabrication environments where angle grinders are the primary tool. Applications include weld seam blending, rust removal, scale removal, and light stock reduction on structural steel, pipe, and plate. The 80-grit designation provides a balance between fast cut rate and a reasonably smooth finish, making it a common choice for initial surface prep before finer finishing steps. The case contains 10 discs, making it practical for shop stocking or job-site supply.
