Norton 77696090179 Flap Disc 120 Grit Type 27 2 Inch

Product Description

The NORTON 77696090179 is a Type 27 coated flap disc designed for grinding and blending applications on metal and fabricated surfaces. Built with zirconia alumina abrasive at 120 grit (fine grade), it delivers consistent stock removal and a smooth finish in a single pass. The fiberglass backing provides structural rigidity under load, and the Quick-Change Type S attachment allows for fast disc swaps without additional hardware. Rated to 30,000 RPM, this disc is suited for use with compatible right-angle die grinders and rotary tools found on the shop floor or in the field.

This flap disc is intended for metal fabrication, weld blending, deburring, and surface conditioning tasks common in industrial, maintenance, and construction environments. The 2-inch disc diameter makes it well suited for work in tight spaces or on contoured surfaces where larger discs cannot maneuver. Metalworkers, pipefitters, and maintenance technicians typically reach for this size when precision grinding on small weldments or irregular geometry is required.

Key Features

• 120 grit zirconia alumina abrasive for fine-grade material removal and surface blending
• Type 27 flat profile positions the abrasive parallel to the workpiece for flat surface grinding
• Quick-Change Type S attachment for tool-free disc changes on compatible spindles
• Fiberglass backing offers rigidity and resistance to flex under rotational load
• 30,000 RPM maximum speed rating for use with high-speed rotary tools
• Compact 2-inch diameter suited for confined areas and detail work

Compatibility

Designed for use with right-angle grinders and die grinders equipped with a Quick-Change Type S spindle interface that accept 2-inch Type 27 flap discs rated at or below 30,000 RPM.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety practices. Confirm the tool spindle speed does not exceed the 30,000 RPM rating marked on the disc before mounting. Inspect the disc for damage before each use and never mount a cracked or visibly worn disc. Always install and use appropriate eye, face, and hand protection in accordance with ANSI B11 and applicable shop safety standards.
