3M 7010362436 Straight Cartridge Roll 320 Grit 1/2 in

Product Description

The 3M 7010362436 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight contours and internal bores. Built with aluminum oxide abrasive on a cloth backing, this roll delivers consistent material removal at a 320 grit, very fine grade rating. It is rated for a maximum spindle speed of 24,000 RPM, making it compatible with standard die grinders and cartridge roll mandrels used in metalworking and finishing operations. Machinists, fabricators, and maintenance technicians reach for this roll when close-tolerance surface prep is required in areas that larger abrasives cannot reach.

This cartridge roll is suited for use on ferrous and non-ferrous metals in both production and repair environments. Typical applications include finishing weld joints inside tubing, blending inside radius cuts, and preparing bores for inspection or coating. The very fine 320 grit is best applied as a finishing step after coarser stock removal has been completed, producing a smooth, consistent surface profile.

Key Features

• 320 grit aluminum oxide abrasive for very fine surface finishing
• Cloth backing provides durability and flexibility in curved or contoured workpieces
• Rated to 24,000 RPM for use with standard high-speed die grinders
• 0.5 inch diameter fits standard mandrels sized for 1/2 inch cartridge rolls
• Straight cartridge profile for consistent contact in cylindrical and bore applications

Compatibility

Designed for use with mandrels and die grinders that accept 1/2 inch diameter straight cartridge rolls at spindle speeds up to 24,000 RPM.

Installation Notes

Cartridge rolls are installed and removed by a qualified operator using the appropriate mandrel size for the roll diameter. Confirm the die grinder or rotary tool does not exceed the 24,000 RPM maximum rated speed before use. Always power down and disconnect the tool before mounting or dismounting the roll. Wear appropriate eye and face protection as required by shop safety standards and applicable OSHA guidelines.
