Merit Abrasives 69957339771 Cartridge Roll 60 Grit 1/2 in

Product Description

The MERIT ABRASIVES 69957339771 is a straight cartridge roll designed for precision grinding, deburring, and surface blending in tight spaces and contoured areas. Built with a ceramic alumina abrasive on a cloth backing, this roll delivers consistent stock removal at a coarse 60 grit rating. It measures 0.5 inches in diameter and 1.5 inches in length, making it well suited for mandrel-mounted use in die grinders and rotary tools. With a maximum operating speed of 23,000 RPM, it maintains stability under high-speed conditions. Metalworkers, machinists, and fabricators rely on this type of roll for interior bore work and weld cleanup where flat abrasives cannot reach.

This cartridge roll is appropriate for use on ferrous and non-ferrous metals in both shop and field environments. Its coarse 60 grit ceramic alumina construction makes it effective for aggressive material removal on steel, stainless steel, and aluminum. The cloth backing provides flexibility to conform to curved or irregular surfaces. Typical applications include die and mold work, port matching, weld blending, and bore finishing in manufacturing, maintenance, and repair operations.

Installation Notes

Installation is performed by machinists or fabricators using a compatible mandrel sized to the roll diameter. Ensure the mandrel and roll assembly are properly secured before operation and verify that the tool speed does not exceed the 23,000 RPM maximum rating. Always use appropriate eye protection and follow shop safety protocols when operating rotary abrasive tools. Inspect the roll for wear or damage before each use and replace if the abrasive layer shows uneven wear or the backing shows signs of separation.
