The MERIT ABRASIVES OLD08834180308 is a straight cartridge roll designed for precision internal and contour grinding, deburring, and surface blending in metalworking applications. Built with aluminum oxide abrasive, this roll delivers consistent material removal at an 80 grit medium grade, making it well-suited for smoothing weld seams, refining bores, and cleaning up inside radii. The 1/2 inch diameter profile fits standard mandrels used with die grinders and rotary tools. Machinists, fabricators, and tool-and-die technicians are the primary installers of this consumable abrasive.
This cartridge roll is intended for use on ferrous and non-ferrous metals in shop and field metalworking environments. Typical applications include deburring drilled or reamed holes, blending internal contours on fabricated weldments, and surface conditioning in tight spaces where flat abrasive sheets or grinding wheels cannot reach. The 80 grit medium grade positions this roll between aggressive stock removal and finer finishing work, making it a general-purpose choice for prep and blend operations.
Designed as an OEM-style replacement or direct-use abrasive consumable for straight cartridge roll mandrel setups on die grinders and rotary tools accepting a 1/2 inch diameter roll.
Installation is performed by machinists or metal fabricators using a compatible mandrel and rotary power tool. Ensure the mandrel is properly tightened and rated for the RPM of the grinder before use. Wear appropriate eye protection and follow shop safety protocols when operating rotary abrasives. Inspect the roll for damage or looseness before each use and replace if the abrasive shows uneven wear or separation.
