3M 7100105521 Aluminum Oxide Square Pad 60 Grit

Product Description

The 3M 7100105521 is an aluminum oxide square abrasive pad designed for surface preparation, blending, and finishing tasks on metal, wood, and composite materials. Running at up to 12,000 RPM, this pad delivers consistent stock removal at a 60-grit medium grade. The cloth backing with X-weight construction resists tearing under load and provides dimensional stability during aggressive passes. At 2 inches long by 2 inches wide by 0.375 inches thick, it fits compact random-orbit and right-angle tools commonly used by machinists, fabricators, and maintenance technicians for tight-clearance work.

This pad is suited for both shop and field use where controlled material removal is needed on flat or near-flat surfaces. Typical applications include weld seam blending, surface scale removal, and prep work before coating or plating. The 1/4-20 inch eyelet size matches standard mandrel fittings found on die grinders and right-angle grinders. It is a practical choice for metalworking, general fabrication, and MRO maintenance operations where a small-format, medium-grit abrasive is required.

Key Features

• 60-grit aluminum oxide abrasive provides medium-grade stock removal on metal and wood
• Rated to 12,000 RPM for use with high-speed die grinders and right-angle tools
• X-weight cloth backing resists tearing and flexing under continuous load
• Compact 2 x 2 inch square format fits tight workspaces and detail areas
• 1/4-20 inch eyelet size for direct mandrel mount on standard tooling

Compatibility

Designed for use with die grinders, right-angle grinders, and similar rotary tools equipped with a 1/4-20 inch mandrel fitting and capable of operating within the 12,000 RPM maximum speed rating.

Installation Notes

Mount the pad onto a compatible 1/4-20 inch mandrel and verify the tool speed does not exceed 12,000 RPM before operation. Inspect the pad for damage or wear before each use and replace if the backing shows fraying or delamination. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary abrasive tools.
