Cratex 80 M Surface Grinding Wheel Silicon Carbide Medium

Product Description

The CRATEX 80 M is a small-diameter surface grinding wheel engineered for precision deburring, smoothing, and surface finishing on tight-tolerance workpieces. It measures 1 inch in diameter and 1/8 inch thick, with a 1/16-inch hole size, making it well-suited for spindle-mounted applications where control and accuracy matter. The wheel uses a silicon carbide abrasive in a rubber bond at a medium grade, which produces consistent stock removal while leaving a clean surface finish. It is rated to 25,000 RPM, supporting use on high-speed rotary tools and grinding spindles. Licensed trade professionals and precision fabricators are the primary installers.

This wheel is designed for precision grinding and finishing applications across a wide range of industries and materials. Typical use cases include work on aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super-sensitive scientific devices. Its compact 1-inch diameter makes it practical for intricate or recessed surfaces where larger wheels cannot access. The rubber bond provides a degree of flexibility that reduces chipping risk on delicate or brittle workpieces.

Key Features

• Silicon carbide abrasive delivers sharp, consistent cutting action on hard and brittle materials
• Rubber bond construction offers controlled flexibility, reducing risk of surface damage on precision parts
• Medium grade provides a balance between stock removal rate and surface finish quality
• Rated to 25,000 RPM for compatibility with high-speed rotary and spindle grinding tools
• No recess design simplifies mounting and maximizes usable wheel face
• Compact 1-inch diameter accesses tight geometries, recesses, and intricate component features

Compatibility

Suitable for use on aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super-sensitive scientific devices. Designed for spindle-mounted rotary grinding applications with tool speeds up to 25,000 RPM.

Installation Notes

Mounting and operation should be performed by qualified personnel familiar with abrasive wheel safety practices. Always verify that the tool spindle speed does not exceed the 25,000 RPM wheel rating before use. Inspect the wheel for cracks or damage before each installation and never use a damaged wheel. Follow applicable ANSI B7.1 abrasive wheel safety standards for mounting, guarding, and operation.
