Cratex A12A36CXH 1/4 Mounted Point 36 Grit Aluminum Oxide

Product Description

The CRATEX A12A36CXH 1/4 is a pointed tree-shaped mounted point abrasive designed for precision grinding, deburring, and surface conditioning on metal and hard materials. It uses an aluminum oxide abrasive matrix at 36 grit, placing it in the very coarse grade range and making it well suited for aggressive stock removal. The shank diameter is 1/4 inch, and the head thickness measures 1-1/4 inches. Maximum operating speed is rated at 27,370 RPM. The medium density construction balances cut rate with point durability during extended use. Machinists, tool and die workers, and metal fabricators are the primary installers and users of this type of abrasive accessory.

This mounted point is used in die grinders, rotary tools, and bench grinder spindle adapters where a pointed tree profile is needed to reach contoured surfaces, bores, grooves, and weld joints. It is appropriate for general metalworking applications in both production shop and maintenance environments. The A12 point shape code designates the pointed tree geometry, which allows access to tight radii and internal profiles that flat or cylindrical wheels cannot reach. The 1/4-inch shank length keeps the working point close to the collet for reduced runout during high-speed operation.

Key Features

• Pointed tree geometry (A12 shape code) for access to contoured and recessed surfaces
• 36 grit aluminum oxide abrasive for aggressive stock removal
• Very coarse grade with medium density for balanced cut rate and point life
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Rated to 27,370 RPM for safe high-speed operation
• 1-1/4-inch head thickness provides extended working surface

Compatibility

Designed for use in die grinders and rotary tools accepting a 1/4-inch shank collet. Confirm tool RPM rating meets or exceeds the 27,370 RPM maximum before mounting.

Installation Notes

A licensed machinist or experienced metalworker should mount and operate this abrasive point following ANSI B7.1 safety guidelines for bonded abrasives. Always power down and disconnect the tool before changing mounted points. Inspect the point for cracks or chips before each use and discard any damaged point immediately. Never exceed the maximum rated RPM marked on the point or stated by the manufacturer.
