Cratex 75430 Rubberized Abrasive Mounted Point Fine 120 Grit

Product Description

The CRATEX 75430 is a rubberized abrasive mounted point designed for precision grinding, deburring, and surface finishing on metal and other hard materials. Built to shape code W160, this point measures 0.25 inches in maximum diameter and 0.25 inches thick, mounted on a 0.125-inch shank for use in rotary tools, die grinders, and similar equipment. The aluminum oxide abrasive is bonded in a rubber matrix at a fine grade, delivering controlled material removal and a smooth surface finish. Rated to 51,000 RPM, it handles high-speed applications while maintaining consistent cut. Machinists, toolroom technicians, and metal fabricators are the primary users of this type of point.

This mounted point is suited for detail work in tight spaces, including port work, weld cleanup, mold and die finishing, and deburring of machined components. Its small diameter and fine 120-grit construction make it appropriate for finishing passes rather than aggressive stock removal. It works on ferrous metals, non-ferrous metals, and hard alloys where a controlled, consistent finish is required. The rubber bond provides a degree of flexibility that reduces chatter and surface gouging compared to vitrified abrasive points.

Key Features

• Shape code W160 geometry for access to confined areas and contoured surfaces
• Fine grade, 120-grit aluminum oxide abrasive for smooth finishing and light deburring
• Rubber-bonded matrix reduces chatter and provides a degree of flexibility during use
• Rated to 51,000 RPM for compatibility with high-speed rotary tools and die grinders
• 0.125-inch shank diameter fits standard collets on most rotary tools and die grinders
• Mounted configuration - ready to install with no additional hardware required

Compatibility

Designed for use in rotary tools and die grinders accepting a 0.125-inch shank mounted abrasive point. Verify that the tool spindle speed does not exceed the 51,000 RPM maximum rating before use.

Installation Notes

Installation and use of mounted abrasive points should follow ANSI B7.1 safety standards for abrasive products. Always power down and disconnect the rotary tool or die grinder before inserting or removing the point. Secure the shank fully in the collet to the depth recommended by the tool manufacturer - do not allow excessive shank overhang. Inspect the point for cracks, chips, or bond separation before each use and discard any damaged point immediately.
