Merit Abrasives 69078645355 Mounted Point W177 80 Grit

Product Description

The MERIT ABRASIVES 69078645355 is a W177 cylinder-shaped mounted point designed for precision grinding, deburring, and surface conditioning on metal and similar hard materials. Built with aluminum oxide abrasive and a resinoid bond, this mounted point delivers consistent stock removal at a coarse 80 grit rating. The medium-density construction balances cut rate and wheel life. Rated to 33,750 RPM, it fits standard die grinders and rotary tools equipped with a 1-1/2-inch shank capacity. Overall length is 2 inches, with a 3/4-inch head thickness. This mounted point is a standard choice for maintenance shops, fabrication facilities, and toolrooms.

This mounted point is suited for use in metalworking applications including weld blending, cavity grinding, port work, and internal surface finishing. The W177 cylinder profile works well in confined areas and on flat internal surfaces. It is commonly used by machinists, tool and die makers, and maintenance technicians working with steel, cast iron, and other ferrous materials. The coarse 80 grit rating makes it appropriate for aggressive material removal rather than fine finishing work.

Key Features

Compatibility

Designed as an OEM-style replacement mounted point for die grinders and rotary tools accepting a standard shank size. Verify spindle speed rating and collet compatibility before installation.

Installation Notes

Mounted points are installed and serviced by machinists, tool and die technicians, and maintenance professionals. Disconnect and de-energize the rotary tool or die grinder before mounting or removing the point. Ensure the tool spindle speed does not exceed the 33,750 RPM rating of this abrasive. Inspect the mounted point for cracks or damage before each use and do not operate damaged abrasives.
