Norton 77696090177 Flap Disc 60 Grit Type 27 2 Inch

Product Description

The NORTON 77696090177 is a 2-inch Type 27 flap disc engineered for aggressive material removal and surface blending in demanding trade environments. It uses a zirconia alumina abrasive at 60 grit, which falls in the medium grade range, making it well suited for grinding welds, deburring metal edges, and blending surfaces on steel, stainless, and other ferrous or non-ferrous substrates. The disc is rated to 30,000 RPM and mounts via a Quick-Change Type S attachment, allowing fast tool changes without additional hardware. A fiberglass backing plate supports the abrasive flaps under load and resists flex failure during extended use. Sheet metal fabricators, pipefitters, and maintenance welders are the primary users of this disc format.

This flap disc is intended for use with compatible right-angle grinders or die grinders that accept Quick-Change Type S accessories. The small 2-inch diameter targets detail work, tight-clearance grinding, and confined weld seams where a larger disc cannot reach. Typical applications include tube and pipe fabrication, structural steel prep, and light stock removal on aluminum and stainless fittings. Its compact size and high RPM rating make it a common choice for professionals working in overhead or restricted positions where tool maneuverability matters.

Compatibility

Designed for use with right-angle grinders and die grinders equipped with a Quick-Change Type S spindle accepting 2-inch flap disc accessories.

Installation Notes

Installation and disc changes should be performed by a qualified operator with the grinder powered off and unplugged or battery removed. Verify the grinder spindle speed does not exceed the 30,000 RPM disc rating before use. Inspect the disc for damage before mounting and do not use a disc that shows cracked, torn, or delaminated flaps. Eye protection, a face shield, and appropriate gloves are standard PPE for abrasive grinding operations.
