Standard Abrasives 7100102977 Cartridge Roll 3/8 in 100 Grit

Product Description

The STANDARD ABRASIVES 7100102977 is a straight cartridge roll designed for precision internal and contour grinding, deburring, and finishing of metal surfaces. Built with aluminum oxide abrasive at 100 grit, this roll delivers a fine-grade cut suitable for controlled material removal and surface blending in tight geometries. At 3/8 inch in diameter, it fits mandrel-driven rotary tools and die grinders commonly used in fabrication and maintenance work. Metalworkers, tool-and-die technicians, and maintenance machinists reach for this type of roll when working bores, slots, and curved profiles that flat media cannot reach.

This cartridge roll is suited for use on ferrous and non-ferrous metals in applications including weld blending, bore finishing, and edge cleanup. The 100-grit aluminum oxide construction is appropriate for intermediate finishing passes where surface consistency matters more than aggressive stock removal. It is commonly used in job-shop fabrication, aerospace component prep, and general industrial maintenance environments requiring repeatable results in confined workspaces.

Key Features

• 100 grit aluminum oxide abrasive delivers fine-grade cutting action
• Straight cartridge roll geometry fits standard mandrels for die grinder and rotary tool use
• 3/8 inch diameter suited for small bores, slots, and tight contours
• Aluminum oxide construction provides consistent cut rate on steel and other ferrous metals
• Lightweight at 0.01 pounds, minimizing added load on handheld tools

Compatibility

Designed as an OEM-style replacement cartridge roll for use with standard mandrels sized to accept 3/8 inch diameter straight cartridge rolls in die grinders and rotary tools.

Installation Notes

Cartridge rolls are installed by a machinist or fabricator onto a compatible threaded mandrel chucked into a die grinder or rotary tool. Confirm the mandrel diameter matches the roll bore before mounting and verify the tool RPM rating does not exceed the roll's rated speed. Secure the roll fully onto the mandrel before powering the tool, and inspect the roll for damage or unraveling before each use.
