Cratex 80391 Surface Grinding Wheel 6in 46 Grit Coarse

Product Description

The CRATEX 80391 is a surface grinding wheel designed for precision material removal on metal, stone, and composite surfaces. At 6 inches in diameter and 1/8 inch thick, this wheel runs in angle grinders and bench grinders fitted with a 1/2-inch arbor. The 46-grit coarse grade removes material aggressively, making it well suited for stock removal, weld dressing, and surface prep work. Licensed trades and skilled fabricators install and use this wheel in shop and field environments where controlled, flat grinding is required.

This wheel is suited for surface grinding applications in metalworking, fabrication, and maintenance shops. The coarse 46-grit abrasive cuts efficiently on ferrous and non-ferrous metals and is a practical choice for initial surface preparation before finer finishing steps. Its compact 1/8-inch thickness allows use in tight clearance setups and on bench grinder spindles where a thinner profile is needed.

Key Features

• 6-inch diameter fits standard bench grinders and angle grinders with compatible guards
• 1/8-inch wheel thickness for use in close-clearance grinding setups
• 1/2-inch center hole for direct spindle or arbor mounting
• 46-grit coarse grade for aggressive stock removal and weld dressing
• Flat wheel profile suited for surface grinding operations

Compatibility

Designed as a replacement or consumable surface grinding wheel for grinders accepting a 6-inch diameter, 1/2-inch arbor wheel with a 1/8-inch thickness profile.

Installation Notes

Grinding wheel installation and replacement should be performed by qualified personnel following applicable ANSI B7.1 safety standards for abrasive wheel use. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and never exceed the maximum RPM rated for the wheel. Ensure the arbor size, flange diameter, and guard clearance are compatible before running.
