Norton 66254461061 Ceramic Flap Disc 7 in 80 Grit Type 27

Product Description

The NORTON 66254461061 is a 7-inch Type 27 ceramic alumina flap disc designed for aggressive material removal on steels, stainless steel, and titanium. Built on a plastic backing plate, this coated abrasive disc runs at up to 8,600 RPM and delivers medium-grade, 80-grit cut rates suited to weld blending, surface conditioning, and stock removal. The trimmable design extends disc life by exposing fresh abrasive as the flaps wear. It mounts via a 7/8-inch arbor hole and fits standard angle grinders used in fabrication, maintenance, and metalworking applications.

This disc is part of the NORTON R980P series and is intended for use on angle grinders in both shop and field environments. The Type 27 flat profile keeps the grinding face flush to the workpiece, making it well suited for flat surface grinding and blending passes. It is commonly selected by metal fabricators, welders, pipefitters, and maintenance mechanics working on carbon steel, stainless steel, and titanium substrates where surface finish and cut rate both matter.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or changing the disc. Verify the grinder spindle speed does not exceed the disc maximum RPM rating of 8,600 before operation. Inspect the disc for damage before each use and never operate with a cracked or delaminated flap disc.
