Cratex 1 M Surface Grinding Wheel 3/8 in Silicon Carbide

Product Description

The CRATEX 1 M is a small-diameter abrasive grinding wheel designed for precision surface work including cleaning and polishing of metal and non-metal surfaces. It measures 0.375 inches in diameter, 3/32 inches thick, with a 1/16-inch arbor hole. The wheel is constructed with a silicon carbide abrasive in a rubber bond matrix and carries a medium grade designation. It is rated to 25,000 RPM, making it suitable for use with high-speed rotary tools. Machinists, tool-and-die makers, and precision fabricators are the typical users for this wheel type.

This wheel is intended for light-duty precision grinding, cleaning, and polishing applications. Its compact 0.375-inch diameter allows access to tight spaces and small workpiece features where larger wheels cannot reach. The rubber bond provides a degree of flexibility and a finer surface finish compared to vitrified bond wheels, making it well suited for final-pass cleaning and deburring on ferrous and non-ferrous parts. The brown color indicates the standard CRATEX rubber-bonded silicon carbide formulation commonly used in toolroom and bench work environments.

Key Features

• 0.375-inch diameter and 1/16-inch arbor hole for use with small rotary tools and mandrels
• 25,000 RPM maximum speed rating supports high-speed tool operation
• No recess design - flat wheel profile for straightforward mounting
• Suitable for cleaning and polishing applications on a variety of workpiece materials

Compatibility

Designed for use with rotary tools and mandrels accepting a 1/16-inch arbor hole. Typical applications include cleaning and polishing as noted in product specifications. No specific tool or machine model compatibility was provided in the product data.

Installation Notes

This wheel should be mounted on a compatible mandrel that matches the 1/16-inch arbor hole before installation into a rotary tool. Verify the tool spindle speed does not exceed the 25,000 RPM maximum rating before operation. Inspect the wheel for cracks or chips before each use and discard any damaged wheels. Eye protection and appropriate PPE are required during grinding and polishing operations.
