Cratex B52A80CXH 1/8 Mounted Point 80 Grit 1/8 in Shank

Product Description

The CRATEX B52A80CXH 1/8 is an aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal and similar hard materials. It features a pointed B52 shape that allows access to tight contours, grooves, and internal cavities where flat or disc abrasives cannot reach. Running at a maximum of 21,000 RPM, this mounted point delivers consistent stock removal at 80 grit medium grade. The 1/8-inch shank mounts directly into standard die grinders, rotary tools, and flexible-shaft machines used by machinists, tool-and-die workers, and maintenance technicians across fabrication and industrial service settings.

This mounted point is suited for light to moderate material removal on steel, cast iron, and non-ferrous metals in both shop and field environments. The pointed geometry targets weld cleanup, port matching, mold finishing, and burr removal in areas requiring precise tip placement. The medium-grade aluminum oxide abrasive provides a balance between cut rate and surface finish quality, making it appropriate for both roughing passes and intermediate finishing work on machined components.

Key Features

• B52 pointed shape for access to tight cavities, grooves, and contoured surfaces
• 80 grit medium aluminum oxide abrasive for balanced cut rate and finish quality
• Maximum rated speed of 21,000 RPM for use with standard die grinders and rotary tools
• 1/8-inch shank diameter fits the most common collet size on die grinders and rotary tools
• 3/4-inch head thickness provides adequate abrasive volume for extended service life
• Medium density and hardness grade suited for general-purpose ferrous and non-ferrous grinding

Compatibility

Designed as a standard mounted point replacement for use with any die grinder, rotary tool, or flexible-shaft machine accepting a 1/8-inch collet or chuck.

Installation Notes

Mounted points must be installed in a collet or chuck rated for the shank diameter and confirmed secure before operating. Always inspect the abrasive for cracks or chips before mounting. Never exceed the rated maximum RPM of 21,000; confirm the tool's rated speed before use. Eye protection and appropriate guarding are required per ANSI B7.1 standards when operating abrasive tooling.
