Standard Abrasives 7100098787 Cartridge Roll 80 Grit

Product Description

The STANDARD ABRASIVES 7100098787 is a straight cartridge roll designed for precision grinding, deburring, and surface blending in tight bores, slots, and contoured surfaces. Built with a zirconia alumina abrasive grain, this roll delivers aggressive stock removal and long service life on ferrous metals, stainless steel, and hard alloys. At 0.5 inches in diameter and 2.5 inches in overall length, it fits a 0.25 inch pilot hole mandrel and is rated to a maximum of 18,000 RPM. It is suited for metalworking and fabrication applications where a standard flat sheet or flap disc cannot reach.

This cartridge roll is used in industrial and shop settings where internal diameter finishing, weld blending inside tubing, or deburring of drilled holes requires a compact, mandrel-mounted abrasive. It is appropriate for use in die grinders and flexible-shaft machines equipped with a compatible 0.25 inch pilot hole mandrel. Common users include metal fabricators, machinists, welders, and maintenance technicians working on ferrous and non-ferrous components requiring controlled material removal in confined areas.

Key Features

• Zirconia alumina grain for aggressive cutting and extended abrasive life on hard metals
• 80 grit for rapid stock removal and weld blending
• 0.5 inch diameter and 2.5 inch overall length for reach into bores and slots
• 0.25 inch pilot hole fits standard mandrels used with die grinders
• Rated to 18,000 RPM for compatibility with high-speed rotary tools

Compatibility

Designed for use with 0.25 inch pilot hole mandrels mounted in die grinders or flexible-shaft rotary tools; verify mandrel diameter and maximum RPM rating before use.

Installation Notes

Always power down and disconnect the tool from its power source before mounting or removing a cartridge roll. Confirm the mandrel is rated to handle the roll diameter and that the tool RPM does not exceed the roll's 18,000 RPM maximum. Inspect the roll for damage before each use and do not force the roll onto the mandrel. Eye protection and appropriate PPE should be worn at all times during grinding operations.
