Cratex B121A36CXH 1/8 Mounted Point 36 Grit Ball Shape

Product Description

The CRATEX B121A36CXH 1/8 is a ball-shaped mounted point abrasive designed for use with rotary tools, die grinders, and similar power tools. It features a 36 grit, very coarse aluminum oxide abrasive with medium density, making it effective for aggressive material removal, deburring, and surface prep on metals and other hard materials. The 1/2 inch head thickness and 1/8 inch shank diameter keep it compatible with standard collets and chucks. Rated to 21000 RPM, this mounted point handles demanding applications without compromising control.

This mounted point is suited for metalworking, fabrication, and maintenance applications in industrial and trade settings. The ball shape (point shape code B121) allows access to contoured surfaces, internal radii, cavities, and hard-to-reach areas where flat or cylindrical abrasives cannot conform. It is commonly used by machinists, tool and die workers, welders, and maintenance technicians for weld cleanup, port blending, and surface conditioning tasks.

Key Features

• Ball shape (B121) for access to curved surfaces, cavities, and internal contours
• 36 grit very coarse aluminum oxide abrasive for aggressive stock removal
• Medium density construction balances cut rate with wheel integrity
• Rated to 21000 RPM for compatibility with standard die grinders and rotary tools
• 1/8 inch shank fits standard collet sizes on common rotary and die grinder tools
• 1/2 inch head thickness provides adequate contact area for surface conditioning work

Compatibility

Designed for use with rotary tools and die grinders that accept a 1/8 inch shank collet. Verify that the tool spindle speed does not exceed the 21000 RPM rating of this mounted point before use.

Installation Notes

Installation is performed by inserting the 1/8 inch shank into the collet or chuck of a compatible rotary tool or die grinder and securing it according to the tool manufacturer's instructions. Always confirm the tool's maximum RPM does not exceed 21000 RPM before operating. Wear appropriate eye protection and ensure the work piece is secured before grinding. Inspect the mounted point for cracks or damage before each use and discard if any defects are found.
