3M 7100105489 Square Abrasive Pad 120 Grit 3x3x0.5 in

Product Description

The 3M 7100105489 is a 3 inches x 3 inches x 0.5 inches square abrasive pad built for fast grinding and blending in tight geometry — channels, fillets, corners, and flat spot work. Constructed with aluminum oxide mineral on an X-weight cloth backing, the 341D pad delivers consistent cut and durability under repeated use. As the pad rotates, its corners provide aggressive biting action, continuously exposing fresh abrasive as the surface wears. At 0.05 pounds per pad, it is a lightweight consumable suited to angle grinder and rotary tool setups used by fabricators, welders, and finishing tradespeople.

This pad is designed for corner weld grinding and cleaning, blending on channels and fillets, and spotting on flat surfaces. The square geometry runs smoothly and gives the operator precise control in confined areas where round pads lose contact or skip. It is commonly used in metal fabrication shops and on-site by tradespeople performing weld cleanup, surface prep, and light stock removal on steel and similar metals.

Key Features

• Square geometry provides corner biting action for fast material removal in fillets and channels
• Aluminum oxide mineral construction delivers consistent cut rate and durability
• X-weight cloth backing resists tearing under grinding loads
• 120 grit P120 rating suits blending, weld cleanup, and surface conditioning
• Corners wear progressively to expose fresh abrasive throughout pad life
• Smooth running profile offers control and access in confined work areas

Compatibility

Designed as an OEM-style consumable abrasive pad for use with compatible rotary grinders and finishing tools that accept 3 inches x 3 inches square pad formats.

Installation Notes

Secure the pad firmly to the backing plate or holder before operation and verify that the tool RPM rating meets or exceeds the pad rating. Power down and disconnect the tool from its power source before mounting or removing abrasive pads. Wear appropriate PPE including eye protection and gloves during grinding operations. Inspect the pad before each use and discard if the backing shows tears, delamination, or uneven wear.
