3M 7100105521 Square Abrasive Pad 2x2x3/8 in 60 Grit

Product Description

The 3M 7100105521 is a 2 inches x 2 inches x 3/8 inches square abrasive pad designed for fast grinding and blending in tight geometry work including channels, fillets, and corners, as well as spotting on flat surfaces. Built on an X-weight cloth backing with aluminum oxide mineral, this pad delivers aggressive cutting action at 60 grit. As the pad rotates, its corners bite into the workpiece and wear down progressively to expose fresh abrasive. Fabricators, welders, and metalworkers rely on this pad format for weld grinding, cleaning, and surface prep where round pads lose access.

This square pad is suited for use in metal fabrication shops and light industrial environments where corner weld grinding and blending in confined areas are common tasks. The square geometry provides access to inside corners and fillets that standard disc pads cannot reach effectively. It is a practical choice for spot grinding and finishing passes on structural steel, channel iron, and similar profiles. Minimum order quantity is 50 units per the manufacturer packaging specification.

Key Features

• Square geometry provides corner access for grinding fillets, channels, and weld toes
• 60 grit aluminum oxide mineral for aggressive stock removal and blending
• X-weight cloth backing for durability under pressure and rotation
• Progressive corner wear exposes fresh abrasive throughout pad life
• Runs smoothly with good operator control in confined work areas

Compatibility

Designed as an OEM-style abrasive pad for use with compatible rotary grinding and finishing tools that accept square pad attachments of this face dimension.

Installation Notes

Installation and mounting of abrasive pads should be performed by qualified personnel following the tool manufacturer guidelines and applicable ANSI B11 or OSHA abrasive wheel safety standards. Ensure the grinder is powered down and disconnected from its power source before changing pads. Inspect the pad for damage before use and never exceed the maximum RPM rating marked on the tool or pad. Use appropriate eye protection and gloves when handling and operating abrasive products.
