Arc Abrasives 37132 Resin Fiber Disc 7x7/8 Inches 120 Grit

Product Description

The ARC ABRASIVES 37132 is a resin fiber disc designed for aggressive surface grinding and finishing on metal workpieces. Measuring 7 inches in diameter with a 7/8-inch arbor hole, it runs at 120 grit for medium-fine stock removal and surface blending. The disc combines a resin-bonded abrasive grain with a fiber backing and an integrated grinding aid that reduces heat buildup and loading. The result is consistent cut rate and extended disc life across a wide range of metal grinding tasks. Metal fabricators, welders, and industrial maintenance crews are the primary users of this disc type.

This disc is suited for grinding, blending, and finishing operations on steel, aluminum, stainless steel, and other non-ferrous metals. Typical applications include weld seam blending, surface preparation before coating, and deburring on flat or slightly contoured workpieces. The 120-grit designation makes it appropriate for intermediate finishing passes where a smoother surface profile is required without sacrificing too much material removal rate. It fits standard right-angle grinders configured for 7-inch resin fiber discs with a 7/8-inch arbor.

Key Features

• 7-inch diameter with 7/8-inch arbor hole fits standard right-angle grinders
• 120 grit delivers medium-fine material removal and surface blending
• Resin fiber backing provides structural rigidity under grinding pressure
• Integrated grinding aid reduces heat and disc loading during use
• Compatible with steel, aluminum, stainless steel, and other non-ferrous metals

Compatibility

Designed as an OEM-style replacement or standard-fit disc for right-angle grinders that accept 7-inch resin fiber discs with a 7/8-inch arbor hole.

Installation Notes

Resin fiber discs are installed and serviced by metal fabricators, welders, and industrial maintenance technicians. Before mounting, ensure the grinder is unplugged or the power source is locked out. Inspect the disc for cracks or damage before each use and never operate above the disc's rated RPM. Use the appropriate backing pad specified for 7-inch resin fiber disc applications.
