3M 7100104910 Flap Disc 7 Inch 80 Grit Right Angle

Product Description

The 3M 7100104910 is a 7-inch right-angle flap disc designed for medium to high-pressure grinding and finishing work on metal surfaces. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this disc delivers a fast, consistent cut rate throughout its service life. Individual flaps break down progressively during use, continuously exposing fresh abrasive mineral so cut rate stays steady from start to finish. Typical applications include beveling, weld removal, and edge deburring on steel, stainless, and similar metals. Licensed trades and fabrication professionals rely on this disc where both material removal speed and surface finish quality matter in the same operation.

This flap disc is suited for residential and commercial metal fabrication, structural steel work, weld prep and cleanup, and general grinding tasks that require an 80-grit cut with a smoother result than fiber discs or bonded grinding wheels typically produce. The right-angle configuration fits standard angle grinders commonly used by ironworkers, pipefitters, welders, and sheet metal mechanics. The 80-grit designation places it in the medium-aggressive range, appropriate for blending welds, shaping edges, and removing mill scale without excessive stock removal.

Key Features

• 3M Precision-Shaped Grain provides a fast, aggressive cut on a variety of metals
• Durable polyester backing handles high unit pressure without delaminating
• Progressive flap breakdown exposes fresh mineral, maintaining a consistent cut rate for the life of the disc
• 80-grit rating balances material removal with surface finish quality
• Right-angle design fits standard angle grinders used in fabrication and field work
• Lower risk of gouging compared to fiber discs and bonded abrasive wheels

Compatibility

Designed as an OEM-specification flap disc for use on right-angle grinders accepting 7-inch abrasive discs in metal grinding and finishing applications.

Installation Notes

Installation and disc changes must be performed by a qualified operator with the grinder powered off and unplugged or battery removed. Verify that the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before mounting. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or missing flaps. Operators should wear appropriate PPE including a face shield, gloves, and hearing protection in accordance with ANSI B11 and applicable shop safety standards.
