Cratex A3A36CXI 1/4 Mounted Point A3 36 Grit 2.75in

Product Description

The CRATEX A3A36CXI 1/4 is an aluminum oxide mounted grinding point in an A3 tree shape, designed for aggressive material removal on metal, castings, and hard surfaces. With a 36-grit, very coarse abrasive and a hard density rating, this point cuts fast and handles heavy stock removal tasks. The 0.25-inch shank mounts directly into die grinders, rotary tools, and flex-shaft machines used in fabrication, maintenance, and toolroom applications. A rated maximum spindle speed of 10,730 RPM allows it to run safely in standard die grinder setups. It is a single-piece consumable stocked individually and ordered individually.

This mounted point suits applications in metal fabrication shops, maintenance and repair operations, foundries, and industrial finishing environments. The tree-shaped A3 profile allows access into contoured surfaces, recessed cavities, and irregular geometries where flat or cylindrical wheels cannot reach. Typical users include machinists, tool and die makers, welders performing weld cleanup, and maintenance technicians deburring castings or removing scale from ferrous and non-ferrous workpieces.

Key Features

• A3 tree-shape profile for access into contoured and recessed surfaces
• 36-grit aluminum oxide abrasive for very coarse, high-removal-rate grinding
• Hard density rating for aggressive cutting on tough materials
• 0.25-inch shank diameter compatible with standard die grinder collets
• Maximum rated speed of 10,730 RPM for use in typical rotary tool setups
• 2.75-inch head thickness provides extended working surface

Compatibility

Designed for use with die grinders, rotary tools, and flex-shaft machines accepting a 0.25-inch shank collet. Suitable for grinding ferrous metals, castings, and similar hard materials in fabrication and MRO applications.

Installation Notes

Installation is performed by machinists or trades personnel familiar with rotary abrasive tooling. Before mounting, confirm the tool spindle speed does not exceed 10,730 RPM. Secure the shank fully into the collet and tighten per the tool manufacturer's specifications before operating. Always wear appropriate eye and face protection when using mounted abrasive points, and inspect the point for chips or damage before each use.
