Merit Abrasives 69078645346 Mounted Point W163 80 Grit

Product Description

The MERIT ABRASIVES 69078645346 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Shaped to the W163 cylinder profile, it measures 0.5 inches thick with a 1/8 inch shank diameter and a 1.5 inch shank length for a 2 inch overall length. The resinoid bond holds the 80 grit abrasive grain at a medium density and hardness, delivering consistent coarse material removal on ferrous metals, castings, and hardened steel. Rated to 60,000 RPM, this point is suited for use in die grinders and rotary tools where access and control matter.

This mounted point is used in metalworking, tool and die, weld cleanup, and maintenance grinding applications. Its compact cylinder geometry makes it well suited for internal bore work, slot finishing, and cleaning up weld seams in recessed areas. Machinists, fabricators, and maintenance technicians commonly reach for this style of point when working with die grinders on castings, molds, and metal components that require controlled stock removal in confined spaces.

Installation Notes

Mounted points are installed and removed by a licensed or trained machinist or grinding technician using the appropriate collet wrench for the die grinder. Always power down and unplug or de-energize the tool before changing mounted points. Inspect the point for cracks or chips before each use and never exceed the rated maximum RPM marked on the packaging. Applicable safe use guidelines are outlined in ANSI B7.1 for abrasive wheel safety.
