Cratex A12A120CXG 1/4 Mounted Point 120 Grit Fine Aluminum Oxide

Product Description

The CRATEX A12A120CXG 1/4 is a rubber-bonded aluminum oxide mounted point designed for precision grinding, deburring, and surface finishing on metal, alloys, and hard materials. Shaped in the A12 pointed tree profile, it delivers controlled contact in tight radii, contoured surfaces, and hard-to-reach internal geometries. At 120 grit with a fine grade and soft density, it removes material smoothly without aggressive stock removal, making it well suited for finishing passes and light blending work. The 1/4-inch shank connects directly to die grinders, rotary tools, and flexible shaft machines. Rated to 27,370 RPM, it handles typical rotary tool operating speeds without issue.

This mounted point fits standard rotary and die grinder applications in metalworking, fabrication, maintenance, and toolroom environments. The pointed tree shape (A12) is commonly used to dress weld beads, clean casting flash, refine port work, and finish contoured bores or cavities. It is appropriate for both bench-mounted rotary tools and handheld die grinders. Typical users include machinists, welders, metal fabricators, and maintenance technicians working on ferrous and non-ferrous materials.

Key Features

• A12 pointed tree shape for access to contoured surfaces, tight radii, and internal profiles
• 120 grit aluminum oxide abrasive for fine, smooth finishing and light material removal
• Soft density provides consistent cut with reduced glazing on finished surfaces
• 1/4-inch shank diameter fits standard die grinders and rotary tool chucks
• Maximum rated speed of 27,370 RPM suits common handheld rotary tool operating ranges
• 1-1/4 inch head thickness delivers adequate contact length for blending and finishing passes

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4-inch shank mounted point. No specific model compatibility was provided in the product data.

Installation Notes

Mounted points are installed and serviced by machinists, fabricators, and maintenance technicians using standard die grinders or rotary tools. Always confirm the tool spindle speed does not exceed the 27,370 RPM maximum rated speed before operating. Inspect the mounted point for cracks, chips, or shank damage before each use and do not use a damaged abrasive. Disconnect or power down the rotary tool before installing or removing the mounted point, and ensure the shank is fully seated and the collet is properly tightened before operation.
