Norton 66261183495 Flap Disc 40 Grit Type 29 7 Inch

Product Description

The NORTON 66261183495 is a Type 29 coated flap disc designed for aggressive material removal on steel, stainless steel, and titanium. It runs a 40-grit zirconia alumina abrasive bonded to a fiberglass backing, delivering coarse-grade grinding performance at up to 8,500 RPM. The conical Type 29 geometry presents the abrasive at an angle, increasing contact area and cutting speed compared to a flat Type 27 disc. This disc fits a 7/8 inch arbor hole and is sized at 7 inches in diameter. It is part of the R980P series and is well suited for weld blending, surface conditioning, and stock removal in fabrication and maintenance work.

This flap disc is intended for use with angle grinders in industrial and trade settings. Typical applications include weld seam removal, deburring, and surface prep on structural steel, stainless tubing, and titanium components. The coarse 40-grit rating makes it appropriate for initial material removal passes rather than finishing work. Fabricators, pipefitters, and maintenance technicians working on metal structures or process equipment are the primary users of this type of disc.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety procedures. Always disconnect or power down the grinder before mounting or removing the disc.
