Merit Abrasives 08834180218 Cartridge Roll 3/8in 180 Grit

Product Description

The MERIT ABRASIVES 08834180218 is a straight cartridge roll designed for precision grinding, blending, and finishing in tight contours and hard-to-reach areas. Built with aluminum oxide abrasive, it delivers consistent stock removal and surface refinement across metal and other hard substrates. At 3/8 inch in diameter and rated at 180 grit, this roll falls in the very fine grade range, making it suited for finishing passes where surface quality matters. Machinists, tool and die workers, and metal fabricators typically reach for this type of roll when deburring bores, slots, and internal radii with a mandrel-mounted die grinder or drill press.

This cartridge roll is appropriate for use on ferrous and non-ferrous metals in both production and job-shop settings. The aluminum oxide grain cuts cleanly on steel, stainless, and aluminum, and holds up well under moderate pressure. The 180 grit level is commonly used for pre-polish finishing, light deburring, and surface prep before coating or inspection. It is well suited for aerospace, automotive, and general metalworking applications where fine surface finish on small-diameter internal features is required.

Key Features

• Aluminum oxide abrasive for reliable cutting action on ferrous and non-ferrous metals
• 180 grit very fine grade for finishing, light deburring, and pre-polish surface prep
• 3/8 inch diameter straight profile fits standard mandrels for die grinders and drill presses
• Straight cartridge roll construction maintains consistent contact in bores, slots, and contoured recesses
• Lightweight at 0.01 pounds per unit, suitable for high-cycle production use

Compatibility

Designed for use with standard mandrel tooling sized to accept 3/8 inch diameter straight cartridge rolls, compatible with die grinders, drill presses, and flex-shaft tools commonly used in metal finishing and fabrication.

Installation Notes

Installation of cartridge rolls is performed by machinists or metalworking technicians using a compatible mandrel. Ensure the mandrel diameter matches the roll bore before mounting, and verify that the tool's RPM rating does not exceed the roll's maximum rated speed. Power down and disconnect the tool from the power source before changing rolls. Inspect the roll for tears or unraveling before each use and replace immediately if damage is found.
