Merit Abrasives 08834182540 Cartridge Roll 3/8 in 80 Grit

Product Description

The MERIT ABRASIVES 08834182540 is a full taper cartridge roll designed for precision deburring, blending, and finishing in tight contours, slots, and internal bores. Built with aluminum oxide abrasive at 80 grit, this medium-grade roll delivers consistent stock removal and surface refinement on ferrous and non-ferrous metals. The full taper profile collapses and conforms as the roll wears, maintaining contact across irregular surfaces. At a maximum roll diameter of 3/8 inch, it fits mandrel-driven rotary tools commonly used by metalworkers, machinists, fabricators, and maintenance technicians.

This cartridge roll is suited for die grinder and rotary tool applications where internal surface finishing is required. Typical use cases include weld blending inside tubing, port work, cleaning casting flash, and finishing drilled or machined bores in shop and field environments. The 80-grit medium grade makes it appropriate for initial surface prep and moderate material removal before finer finishing stages.

Compatibility

Designed for use with standard cartridge roll mandrels on die grinders and rotary tools accepting rolls up to 3/8 inch maximum diameter. Verify mandrel shank size and arbor compatibility before installation.

Installation Notes

Installation is performed by metalworkers, machinists, and fabricators using mandrel-driven rotary tools or die grinders. Power down and disconnect the tool from its power source before mounting or removing the cartridge roll. Seat the roll fully onto the mandrel and tighten per the mandrel manufacturer's instructions before operation. Always wear appropriate eye and face protection and operate within the tool's rated RPM for the roll size.
