Cratex B121A80CXH 1/8 Mounted Point 80 Grit Ball Shape

Product Description

The CRATEX B121A80CXH 1/8 is a rubber-bonded aluminum oxide mounted point in a B121 ball shape, designed for precision grinding, deburring, and surface blending on metal and other hard materials. With an 80-grit medium grade abrasive, this mounted point delivers consistent stock removal while maintaining reasonable surface finish. The 1/8-inch shank fits standard die grinders, rotary tools, and flexible shaft machines. It is sized for detail work in confined areas where larger wheels cannot reach. Rated to 21,000 RPM, it handles high-speed rotary tool operation safely within manufacturer limits.

This mounted point is suited for metalworking, tool and die, MRO maintenance, weld blending, and light fabrication applications. It works on steel, cast iron, aluminum, and similar materials. The ball profile makes it well suited for grinding inside bores, contoured recesses, and irregular surfaces. Technicians and machinists use this type of point for touch-up grinding and finishing work where a flat or cylindrical wheel is impractical.

Key Features

• B121 ball shape for grinding in curved, recessed, and contoured surfaces
• 80-grit aluminum oxide abrasive - medium grade for balanced stock removal and finish

Compatibility

Designed to fit rotary tools, die grinders, and flexible shaft machines accepting a 1/8-inch shank mounted point. Verify collet size and maximum RPM rating of the host tool before use.

Installation Notes

Installation and use of mounted points should be performed by machinists or maintenance technicians familiar with abrasive tool safety. Always power down and unplug or lock out the rotary tool before inserting or removing the mounted point from the collet. Confirm the tool RPM rating meets or exceeds the 21,000 RPM rating of this point before operation. Wear appropriate eye protection and follow ANSI B7.1 safety guidelines for the use of abrasive products.
