Norton 77696090182 Flap Disc 60 Grit Type 27 3 Inch

Product Description

The NORTON 77696090182 is a Type 27 coated flap disc designed for grinding and blending on metal surfaces. It uses a zirconia alumina abrasive at 60 grit, placing it in the medium grade range — well suited for aggressive stock removal with a reasonably smooth finish in a single pass. The disc measures 3 inches in diameter and is rated to 30,000 RPM. A fiberglass backing plate provides rigidity under pressure while keeping weight low at 0.021 pounds. It attaches via a Quick-Change Type S system, eliminating the need for a separate backing pad and reducing changeover time between discs.

This disc is used in metal fabrication, welding prep and cleanup, and general surface conditioning on steel, stainless steel, and other ferrous and non-ferrous metals. The compact 3-inch diameter and Quick-Change Type S attachment make it well matched to right-angle die grinders used in tight workspaces or detailed weld blending. It is commonly used by metal fabricators, pipefitters, welders, and maintenance technicians who need a fast-attaching abrasive for spot grinding tasks.

Key Features

Compatibility

Designed for use with Quick-Change Type S compatible right-angle die grinders accepting 3-inch flap discs. Verify that the tool spindle speed does not exceed 30,000 RPM before mounting.

Installation Notes

Installation is performed by metal trades professionals including fabricators, welders, and maintenance technicians. Always confirm the grinder is powered off and disconnected from the air or electrical supply before mounting or removing the disc. Do not exceed the 30,000 RPM maximum speed rating marked on the disc. Inspect the disc for damage before each use and discard any disc that shows delamination, cracking, or excessive wear.
