3M 7100105507 Aluminum Oxide Cross Pad 120 Grit

Product Description

The 3M 7100105507 is an aluminum oxide cross pad designed for fine-grade surface finishing and deburring in tight spaces and contoured areas. Running on a cross or mandrel mount, this pad delivers consistent 120 FEPA grit cutting action on metal, composite, and similar workpiece materials. The X-weight cloth backing provides rigidity and durability under load, while the 8-ply construction resists breakdown during extended use. Rated to 18,000 RPM, it is suited for use with die grinders and right-angle tools common in fabrication, maintenance, and assembly environments. Licensed trade professionals and machinists use this pad for weld blending, edge prep, and surface conditioning.

This cross pad is used in industrial maintenance, metal fabrication, and general machining applications where a small-footprint abrasive is needed to access recessed surfaces, slots, and holes. The 8-32 inch eyelet size fits standard cross-pad mandrels. Its compact 2 x 2 x 0.5 inch profile makes it effective in areas inaccessible to larger abrasive formats. Suitable for ferrous and non-ferrous metals as well as some composite surfaces.

Key Features

• 120 FEPA grit aluminum oxide abrasive for fine-grade stock removal and surface finishing
• X-weight cloth backing provides stiffness and resistance to tearing under rotational load
• 8-ply construction for extended service life and consistent cut rate
• 18,000 maximum RPM rating compatible with standard die grinders and rotary tools
• 8-32 inch eyelet for secure mandrel mounting
• Compact 2 x 2 x 0.5 inch cross pad format reaches confined and contoured work areas

Compatibility

Designed for use with standard 8-32 cross-pad mandrels compatible with die grinders and rotary tools rated to 18,000 RPM or higher.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians using a compatible 8-32 mandrel threaded into the eyelet. Ensure the tool is powered off and unplugged before mounting or removing the pad. Confirm that the tool spindle speed does not exceed the 18,000 RPM rating of this pad before operation. Inspect the pad for damage or separation prior to each use and replace if backing or abrasive shows signs of deterioration.
