Cratex B42A80CXG 1/8 Mounted Point 80 Grit 1/8 in Shank

Product Description

The CRATEX B42A80CXG 1/8 is a mounted abrasive point designed for precision grinding, deburring, and surface finishing on metal and other hard materials. Built with aluminum oxide abrasive in a pointed B42 shape, this mounted point delivers consistent stock removal in tight areas that flat wheels cannot reach. It runs at a maximum of 17,620 RPM on a 1/8-inch shank, making it compatible with standard die grinders, rotary tools, and flexible shaft machines. The 80-grit, medium-grade construction balances cut rate with surface finish for general-purpose material removal tasks.

This mounted point is suited for bench and handheld rotary tool applications in metalworking, fabrication, tool-and-die, and maintenance environments. The pointed B42 profile is well suited for accessing grooves, ports, bores, and contoured surfaces where a cylindrical or flat point would not conform. It is commonly used by machinists, fabricators, and maintenance technicians working on ferrous and non-ferrous metals, as well as hard plastics and composites.

Key Features

• B42 pointed shape for access to confined areas, grooves, and contoured surfaces
• 80-grit aluminum oxide abrasive for medium-grade material removal
• Rated to 17,620 RPM for safe use in standard die grinders and rotary tools
• 1/8-inch shank diameter fits widely available collets and chucks
• 3/4-inch head thickness provides extended working surface life
• Soft density bond allows for consistent abrasive exposure during use

Compatibility

Designed for use with die grinders, rotary tools, and flexible shaft machines fitted with a 1/8-inch collet or chuck. Verify that the tool spindle speed does not exceed the 17,620 RPM maximum rating of this mounted point before use.

Installation Notes

Installation should be performed by a qualified machinist or technician familiar with rotary abrasive tooling. Ensure the tool is fully powered off and unplugged before inserting or removing the mounted point. Insert the shank fully into the collet and tighten securely before operating. Always verify the tool RPM rating does not exceed the maximum RPM marked on this abrasive point, and use appropriate eye protection and guarding per ANSI B7.1 safety standards.
