3M 7100105538 Aluminum Oxide Cross Pad 80 Grit

Product Description

The 3M 7100105538 is an aluminum oxide cross pad designed for precision surface blending, cleaning, and finishing in industrial and trade applications. Running at up to 24,000 RPM, this cross pad delivers consistent stock removal and surface conditioning. The X-weight cloth backing provides stability and durability under load, while the 8-ply construction adds body and resistance to compression. At 80 grit, it falls in the medium grade range, making it suitable for moderate material removal and surface prep tasks. It measures 1 inch long by 1 inch wide by 3/8 inch thick. Machinists, fabricators, and metalworking technicians are the primary installers and users.

This cross pad is commonly used for deburring, blending welds, cleaning bores, and finishing contoured surfaces in tight or hard-to-reach areas. The cross shape allows access to internal cavities, grooves, and irregular geometries where flat or disc abrasives cannot reach. It is well suited for use in manufacturing, maintenance, and repair environments working with metal, composite, and similar substrates. The 3-48 eyelet size is compatible with mandrel-mounted applications on die grinders and similar rotary tools.

Key Features

• 80 grit medium grade aluminum oxide abrasive for moderate material removal and surface conditioning
• Rated up to 24,000 RPM for use with high-speed rotary tools and die grinders
• X-weight cloth backing provides firm support and durability under load
• 8-ply construction adds rigidity and extended service life
• Cross pad geometry reaches bores, grooves, and contoured surfaces inaccessible to flat abrasives
• 3-48 eyelet size for mandrel-mount compatibility

Compatibility

Designed for mandrel-mounted use on die grinders and rotary tools with a 3-48 threaded mandrel. Confirm tool spindle speed does not exceed 24,000 RPM before use.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians. Thread the cross pad securely onto a compatible 3-48 mandrel and verify the mandrel is fully seated before operating. Ensure the tool speed does not exceed the rated 24,000 RPM maximum. Always wear appropriate personal protective equipment, including eye protection and gloves, when operating abrasive tools.
