Cratex 304 M Surface Grinding Wheel 3in Silicon Carbide

Product Description

The CRATEX 304 M is a rubber-bonded silicon carbide surface grinding wheel engineered for precision finishing and surface preparation on metal and non-metal workpieces. Measuring 3 inches in diameter and 1/4 inch thick with a 1/4 inch arbor hole, this medium-grade wheel operates at up to 7000 RPM. The rubber bond matrix cushions the abrasive action, producing a smoother surface finish compared to vitrified or resinoid wheels of similar grit. Machinists, fabricators, and metalworking professionals reach for this wheel when surface quality and controlled material removal matter as much as cut rate.

This wheel suits a wide range of bench grinder and rotary tool applications in both shop and field environments. It is particularly well suited for deburring, polishing, removing heat marks and tarnish, smoothing scratches, stripping rust and corrosion, eliminating excess solder, and general finishing operations on metal surfaces. Its compact 3-inch diameter fits smaller spindle setups and allows access to tighter work areas where larger wheels cannot reach.

Key Features

• Silicon carbide abrasive for effective cutting on ferrous and non-ferrous metals
• Rubber bond construction cushions cut and improves surface finish quality
• Medium grade provides a balance between material removal rate and finish smoothness
• Rated to 7000 RPM for compatibility with standard bench grinders and rotary tools
• No-recess wheel profile for straightforward mounting on standard arbors
• Suitable for corrosion removal, deburring, polishing, and solder cleanup in one wheel

Compatibility

Designed for use in corrosion removal, deburring, excess solder removal, heat mark treatment, polishing operations, rust removal, scratch smoothing, and tarnish removal applications on standard 1/4 inch arbor spindles.

Installation Notes

Installation should be performed by a qualified machinist or metalworking technician following applicable ANSI B7.1 safety standards for abrasive wheel mounting. Power off and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and perform a ring test when applicable. Never exceed the rated 7000 RPM maximum speed marked on the wheel.
