Cratex 75441 Rubberized Mounted Point W163 Medium 70 Grit

Product Description

The CRATEX 75441 is a rubberized abrasive mounted point designed for precision grinding, deburring, and surface finishing on metal, ceramic, and composite materials. Shaped to code W163, this point measures 1/4 inch maximum diameter by 1/2 inch thick and mounts on a 1/8 inch shank for use in rotary tools, die grinders, and flexible shaft machines. The medium-grade, 70-grit aluminum oxide abrasive compound is bonded in a rubber matrix, which provides a self-dressing action and delivers a smoother finish than conventional vitrified wheels. Rated to 26,250 RPM, it handles both light stock removal and fine blending passes. Machinists, tool-and-die technicians, and precision fabricators are the primary installers.

This mounted point is suited for detail work in tight areas where larger grinding wheels cannot reach. Common applications include deburring drilled and tapped holes, blending weld seams, cleaning up casting flash, and polishing internal bores or cavities in ferrous and non-ferrous workpieces. The W163 shape is particularly effective for contoured surface work and confined grinding zones. It is used in both production shop and maintenance-repair environments wherever a controlled, consistent scratch pattern is required.

Key Features

• W163 shape code for contoured and confined-area grinding
• Medium grade, 70-grit aluminum oxide abrasive for controlled stock removal and smooth blending
• Rubber-bonded matrix provides self-dressing action and reduced workpiece chatter
• 1/8 inch shank mounts directly in standard die grinders and rotary tool chucks
• 26,250 RPM maximum speed rating for safe high-speed operation
• Compact 1/4 inch diameter by 1/2 inch profile for access in tight clearances

Compatibility

Designed as an OEM-style abrasive consumable for use in standard 1/8 inch collet die grinders, rotary tools, and flexible shaft handpieces requiring a W163 rubberized mounted point.

Installation Notes

Installation is performed by machinists or fabricators using standard 1/8 inch collet chucks. Before mounting, ensure the tool is fully powered off and unplugged. Thread or press the shank fully into the collet and tighten securely before operation. Never exceed the rated maximum RPM of 26,250; verify the host tool speed rating before use.
