Standard Abrasives 7100103125 Cartridge Roll 3/16 in 180 Grit

Product Description

The STANDARD ABRASIVES 7100103125 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight or contoured areas. Built with aluminum oxide abrasive, it delivers consistent material removal on ferrous and non-ferrous metals. At 3/16 inch in diameter and rated at 180 grit (Very Fine grade), this roll is suited for fine finishing passes where controlled stock removal and a smooth surface finish are the primary goals. It is installed on a mandrel and driven by a rotary tool, die grinder, or drill press, and is a standard consumable in fabrication, maintenance, and tool-and-die work.

This cartridge roll is used in situations where flat abrasive media cannot reach — bores, slots, inside radii, and contoured channels. At the Very Fine 180 grit level, it is typically applied in the later stages of a finishing sequence, after coarser grits have completed primary material removal. Typical installation environments include metal fabrication shops, aerospace component finishing, weld blending on tubing, and general maintenance and repair operations where a fine surface condition is required before coating, anodizing, or inspection.

Key Features

• Aluminum oxide abrasive mineral for reliable performance on ferrous and non-ferrous metals
• 180 grit Very Fine grade for finish work and light blending
• 3/16 inch diameter straight profile for access to narrow bores, slots, and contoured surfaces
• Straight cartridge roll design maintains consistent contact and uniform finish throughout tool life
• Mandrel-mounted — compatible with standard rotary tools and die grinders

Compatibility

Designed as an OEM-style consumable replacement for straight cartridge rolls used with mandrel-driven rotary tools and die grinders in metal finishing and fabrication applications.

Installation Notes

Straight cartridge rolls are installed by threading or pressing onto a compatible mandrel before mounting in a rotary tool, die grinder, or drill press. Verify that the mandrel diameter matches the roll arbor size before use, and confirm the tool RPM rating does not exceed the roll manufacturer maximum. Always wear appropriate eye and face protection when operating abrasive media at speed. Inspect the roll for tears or loosening before each use and replace if degraded.
