Norton 66254461068 Ceramic Flap Disc 80 Grit Type 27

Product Description

The NORTON 66254461068 is a Type 27 ceramic alumina flap disc designed for aggressive material removal on metals including steels, stainless steel, and titanium. Rated at 8600 RPM and carrying an 80-grit medium grade, this disc delivers consistent cut rate and extended life compared to conventional aluminum oxide abrasives. The plastic backing provides rigidity and supports a trimmable design, allowing the operator to expose fresh abrasive as flaps wear. It mounts via a 5/8-11 arbor hole and is suited for use with standard 7-inch angle grinders. The R980P series designation identifies the ceramic grain formulation, which self-sharpens under pressure for sustained cutting performance on hard alloys.

This flap disc is intended for grinding, blending, and finishing operations on ferrous and non-ferrous metals in fabrication, welding, and maintenance applications. Typical users include metal fabricators, pipefitters, structural welders, and maintenance technicians working on carbon steel, stainless steel, and titanium workpieces. The Type 27 flat profile is suited for surface grinding at lower angles rather than edge work, making it appropriate for flat and contoured stock removal. It ships individually and is sold as a single disc per package.

Key Features

• Ceramic alumina abrasive grain for self-sharpening cut and extended disc life on hard metals
• Type 27 flat profile optimized for surface grinding and blending at low work angles
• 80-grit medium grade balances material removal rate with surface finish quality
• Trimmable plastic backing allows exposure of fresh flaps as abrasive wears
• 5/8-11 arbor hole fits standard angle grinder spindles
• 8600 RPM maximum speed rating for use with 7-inch angle grinders

Compatibility

Designed for use on steels, stainless steel, and titanium. Fits angle grinders with a 5/8-11 spindle thread accepting a 7-inch disc at up to 8600 RPM.

Installation Notes

Installation should be performed by a qualified operator following the grinder and abrasive manufacturer guidelines. Verify the grinder spindle speed does not exceed the 8600 RPM disc rating before mounting. Ensure the grinder is unplugged or the power source is locked out before mounting or removing the disc. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of deterioration.
