3M 7100105551 Square Abrasive Pad 80 Grit 2x2x0.5 in

Product Description

The 3M 7100105551 is an aluminum oxide square abrasive pad designed for fast grinding, blending, and cleaning in tight geometry workspaces. Built on an X-weight cloth backing, this pad delivers durability and controlled cut on channels, fillets, corners, and flat surfaces. The 80-grit mineral removes material quickly while the square shape provides corner access that round pads cannot match. As the pad rotates, its corners bite aggressively into the work surface and wear progressively to expose fresh abrasive. Fabricators, welders, and metal finishing technicians reach for this pad when working weld seams and inside corners where conventional discs lose effectiveness.

This square pad is suited for grinding and blending operations on metal fabrication work, including corner weld grinding and post-weld cleaning on structural channels, tubing fillets, and similar profiles. It also performs well for spot grinding on flat surfaces where localized material removal is needed. The 2 inches x 2 inches x 0.5 inches pad size fits standard right-angle die grinder pad holders used in industrial and shop environments. Each pad is sold individually, with a minimum order quantity of 50 units per the manufacturer packaging specification.

Key Features

• Aluminum oxide mineral construction for consistent, fast-cutting abrasive action
• X-weight cloth backing provides durability under aggressive grinding pressure
• Square geometry delivers corner access and biting action on channels, fillets, and welds
• 80-grit rating suited for fast material removal and initial blending passes
• Progressive wear exposes fresh abrasive as pad corners work down
• Smooth running balance supports operator control on detailed or confined surfaces

Compatibility

Designed as an OEM-style replacement square abrasive pad for use with standard right-angle die grinder backup pad holders that accept 2-inch square abrasive pads in metal fabrication and finishing applications.

Installation Notes

This pad is installed by a metalworker or fabricator on a compatible die grinder backup pad holder. Verify the grinder RPM rating meets or exceeds the pad's maximum rated speed before mounting. Always wear appropriate PPE including eye protection and gloves during grinding operations. Inspect the pad and holder for damage before each use and discontinue use if the pad shows uneven wear, tears, or delamination.
