Merit Abrasives 08834180068 Cartridge Roll 240 Grit 1/4 in

Product Description

The MERIT ABRASIVES 08834180068 is a straight cartridge roll abrasive designed for precision internal grinding, deburring, and surface finishing in tight bores, slots, and contoured workpieces. Running on a mandrel mounted to a die grinder or rotary tool, it delivers consistent 240-grit aluminum oxide cutting action across the full contact surface. The aluminum oxide abrasive grain is rated Very Fine grade, making it well-suited for light stock removal and surface refinement rather than aggressive material takedown. Machinists, tool-and-die technicians, and metal fabricators typically reach for this roll when blending surfaces or cleaning up weld areas in confined geometry.

This cartridge roll is used in metalworking and fabrication shops for finishing the interior of bores, cleaning up drilled or reamed holes, and blending contours on ferrous and non-ferrous workpieces. The 0.25-inch diameter profile fits narrow passages where larger abrasive tooling cannot reach. It is a standard single-piece unit sold to meet minimum order requirements common in shop restocking programs.

Key Features

• 240-grit aluminum oxide grain for Very Fine surface finishing and light blending
• Straight cartridge roll profile maintains consistent contact in bores and slots
• 0.25-inch diameter fits narrow internal geometries and tight contoured areas
• Aluminum oxide abrasive provides reliable performance on ferrous and non-ferrous metals
• Mandrel-mounted design compatible with standard die grinder and rotary tool setups

Compatibility

Designed as a standard straight cartridge roll for use with appropriately sized mandrels on die grinders and rotary finishing tools common in metal fabrication and machining applications.

Installation Notes

Installation is performed by machinists or metal fabrication technicians using a compatible mandrel sized to the cartridge roll bore. Ensure the rotary tool or die grinder is fully powered off and unplugged before mounting or removing the roll. Do not exceed the maximum RPM rating of the tool or mandrel. Inspect the roll for damage before use and discard any roll showing tears, unraveling, or excessive wear.
