Merit Abrasives 69078645334 Mounted Point B52 80 Grit

Product Description

The MERIT ABRASIVES 69078645334 is a cone-shaped mounted point designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Built with aluminum oxide abrasive bonded with a resinoid bond, this point delivers consistent material removal at a coarse 80 grit rating. It runs on a 1/8 inch diameter shank and reaches a maximum of 45,370 RPM, making it compatible with standard die grinders and rotary tools used by machinists, fabricators, and tool and die professionals. The medium density construction supports controlled stock removal without excessive loading.

This mounted point is suited for grinding ferrous metals, cast iron, and hardened steel in applications where a standard wheel cannot reach. Typical uses include weld blending, port matching, mold work, and cleanup of interior bores or irregular surfaces. The B52 cone shape provides good contact in concave surfaces and angled profiles. It fits production and maintenance grinding operations in fabrication shops, machine shops, and industrial maintenance settings.

Key Features

• B52 cone point shape for access to contoured and recessed surfaces
• Aluminum oxide abrasive with resinoid bond for consistent, controlled cut
• 80 grit coarse grade for aggressive stock removal
• Rated to 45,370 RPM for use with high-speed die grinders
• Medium density for balanced hardness and cut rate

Compatibility

Designed as a standard mounted point replacement for use with die grinders and rotary tools accepting a 1/8 inch shank collet.

Installation Notes

Mounted points must be installed by securing the shank fully into the collet of the grinder before tightening. Always verify the tool spindle speed does not exceed the 45,370 RPM maximum rating before operation. Inspect the point for cracks or chips before each use and discard any damaged abrasive. Eye protection and appropriate PPE are required during grinding operations per standard shop safety practices.
