Norton 66261132188 Straight Cartridge Roll 60 Grit 3/8 in

Product Description

The NORTON 66261132188 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight bores, slots, and contoured areas. It uses aluminum oxide abrasive bonded to an X-weighted cloth backing, which provides the rigidity and durability needed for aggressive stock removal on ferrous metals and hard alloys. At 60 grit, this roll delivers a coarse cut suited for removing weld scale, burrs, and surface irregularities. The 1/8-inch pilot hole accepts standard mandrels for use with pneumatic or electric die grinders. Maximum operating speed is 23,000 RPM. Trade professionals in metal fabrication, tool-and-die, and maintenance machining rely on this style of roll for work that flat abrasives cannot reach.

This cartridge roll is used in situations where a mounted abrasive must enter a confined space, such as inside a drilled bore, a radiused pocket, or along a weld seam in a tube or pipe. The straight profile maintains consistent contact along the full length of the roll without flaring, making it appropriate for parallel-sided ID grinding applications. It is sold individually but carries a minimum order quantity of 100 units, which suits shop floor consumable replenishment programs and MRO supply accounts.

Compatibility

Designed for use with standard 1/8-inch shank cartridge roll mandrels mounted in pneumatic or electric die grinders rated up to 23,000 RPM.

Installation Notes

Installation is performed by a machinist, toolmaker, or maintenance technician using a compatible mandrel and a die grinder. Ensure the grinder is powered off and depressurized before mounting or removing the roll. Always confirm the grinder speed does not exceed the 23,000 RPM maximum rating marked on the roll. Wear appropriate eye and face protection during operation, as abrasive contact work can generate metal and abrasive particle debris.
