3M 7100170656 Tapered Cartridge Roll P150 3/8x1x1/8in

Product Description

The 3M 7100170656 is an aluminum oxide full tapered cartridge roll designed for precision grinding and finishing on contoured surfaces, slots, and hard-to-reach areas. Built on a durable X-weight cloth backing with a resin bond, it delivers consistent heat resistance and extended service life under sustained abrasive load. At P150 grit, it is suited for intermediate finishing work where surface refinement is the goal. The tapered cartridge profile allows the roll to conform to grooves and irregular geometries that flat abrasive media cannot reach. This product is sold by the roll and is a standard choice for metal fabrication and tool room finishing applications.

This cartridge roll is used in die grinder and mandrel-based finishing operations across metalworking, aerospace component prep, weld blending, and general fabrication environments. Its 3/8 inch outer diameter, 1 inch length, and 1/8 inch arbor size fit standard tapered mandrels used by machinists, metal finishers, and tool and die technicians. The P150 X-weight construction makes it effective for controlled stock removal and pre-polish surface work on ferrous and non-ferrous metals.

Key Features

• Aluminum oxide abrasive mineral for consistent cut rate on metal surfaces
• X-weight cloth backing provides durability and flexibility under load
• Resin bond construction resists heat buildup during extended use
• Full tapered profile conforms to grooves, slots, and contoured geometries
• P150 grit suited for intermediate finishing and pre-polish stages
• 3/8 inch diameter by 1 inch length with 1/8 inch arbor for standard mandrel compatibility

Compatibility

Designed for use with standard tapered mandrels that accept a 1/8 inch arbor, as used in die grinders and rotary tools common to metal finishing and fabrication applications.

Installation Notes

Installation is performed by metalworking and finishing technicians using a compatible tapered mandrel mounted in a die grinder or rotary tool. Confirm mandrel size matches the 1/8 inch arbor before mounting. Operate within the grinder manufacturer's rated RPM to avoid abrasive failure. Wear appropriate eye and hand protection during use.
