Cratex A3A36CXH 1/4 Mounted Point 36 Grit Tree Shape

Product Description

The CRATEX A3A36CXH 1/4 is an aluminum oxide mounted point designed for aggressive material removal in grinding, deburring, and surface finishing applications. It features an A3 tree point shape with a 36-grit, very coarse grade that cuts fast on ferrous and non-ferrous metals, castings, and hard-to-reach contours. The medium-density bond holds abrasive grain firmly during high-load passes. Rated to 10,730 RPM, this mounted point is built for use with pneumatic die grinders, rotary tools, and high-speed electric handpieces used across tooling, fabrication, and maintenance trades.

This mounted point is suited for deburring weld seams, cleaning casting flash, shaping hard materials, and accessing recessed or contoured surfaces that flat wheels cannot reach. The tree profile makes it especially useful for working inside bores, cavities, and irregular geometry. It is a common choice in metal fabrication shops, tool and die operations, and MRO maintenance environments where controlled stock removal in tight areas is required.

Key Features

• A3 tree point shape for accessing contoured surfaces, bores, and recessed geometry
• 36 grit, very coarse grade for fast, aggressive stock removal
• Aluminum oxide abrasive material suitable for ferrous metals, castings, and hard alloys
• Medium density bond provides firm grain retention during heavy grinding passes
• 10,730 RPM maximum speed rating for use with standard die grinders and rotary tools
• 1/4 inch shank diameter fits standard collets on most pneumatic and electric rotary tools

Compatibility

Designed for use with pneumatic die grinders, electric rotary tools, and handheld high-speed grinders equipped with a 1/4 inch collet. Verify the tool spindle speed does not exceed the 10,730 RPM maximum rated speed of this mounted point before use.

Installation Notes

Mounting and tool changes should be performed with the air supply disconnected or the tool powered off and fully stopped. Seat the 1/4 inch shank fully into the collet and tighten the collet nut securely before operation. Always verify the tool RPM rating does not exceed the mounted point maximum speed rating. Wear appropriate eye protection and follow applicable ANSI B11 or OSHA grinding safety guidelines during use.
