3M 7100105478 Square Abrasive Pad 80 Grit 3x3 Inch

Product Description

The 3M 7100105478 is a 3 inches x 3 inches x 0.5 inches square abrasive pad designed for fast grinding and blending on channels, fillets, corners, and flat surfaces. Built on an X-weight cloth backing with aluminum oxide mineral, the 341D construction delivers durable, consistent cut throughout the life of the pad. As the pad rotates, its corners provide aggressive biting action and wear down progressively to expose fresh abrasive. At 80 grit, this pad suits medium-to-aggressive stock removal and surface prep in metalworking and fabrication environments.

This square pad is suited for use on weld grinding, weld cleanup, and surface blending tasks in both shop and field settings. The square geometry provides access to tight corners and fillets where round pads cannot reach. It is a practical choice for metal fabricators, welders, and industrial maintenance techs working on structural steel, channels, and angle iron. Minimum order quantity is 50 units per purchase, making it appropriate for production or shop restocking.

Key Features

• Square geometry allows access to corners, fillets, and channels that round pads cannot reach
• 80 grit aluminum oxide mineral for medium-to-aggressive grinding and blending
• X-weight cloth backing provides durability under sustained rotational load
• Progressive corner wear continuously exposes fresh abrasive for consistent cut rate
• Runs smoothly for controlled material removal on flat and contoured surfaces

Compatibility

Designed as an OEM-style replacement abrasive pad for rotary tool and grinder applications where a 3 inches x 3 inches square pad format is specified.

Installation Notes

Installation and mounting should be performed by qualified metalworking or maintenance personnel familiar with abrasive tool safety. Ensure the rotary tool or grinder is fully powered down and unplugged before mounting or changing the pad. Verify that the tool spindle speed rating meets or exceeds the pad speed rating before operation. Follow applicable ANSI abrasive safety standards and always use appropriate eye and hand protection when operating abrasive pads.
