3M 7100034253 Depressed Center Grinding Wheel 24 Grit

Product Description

The 3M 7100034253 is a depressed center grinding wheel designed for aggressive material removal on a wide variety of metals. It measures 7 inches in diameter with a 1/4-inch-thick grinding face and a 5/8-11 internal arbor thread for secure mounting on standard angle grinders. The wheel is built with proprietary Cubitron abrasive grain bonded into the wheel body, delivering consistent cut rates while producing less noise and vibration than conventional bonded abrasives. At 1.222 pounds, it is well-suited for sustained grinding applications where operator fatigue and tool control matter.

This wheel is intended for use in metal fabrication, maintenance, and repair environments where depressed center wheels are the standard tool for weld grinding, surface prep, and stock removal. It fits 7-inch right-angle grinders with 5/8-11 spindle threads. The 24-grit designation makes it appropriate for fast, coarse material removal rather than finishing work. Typical users include fabricators, ironworkers, pipefitters, and maintenance technicians working on structural steel, plate, pipe, and other ferrous and non-ferrous metals.

Key Features

• Cubitron abrasive grain construction for consistent, high-rate material removal
• 24 grit rating suited for coarse grinding and rapid stock removal
• Reduced noise and vibration compared to conventional bonded wheels
• 5/8-11 internal arbor thread fits standard 7-inch angle grinders
• Depressed center profile allows flush grinding near edges and welds

Compatibility

Designed for use on 7-inch right-angle grinders equipped with a 5/8-11 spindle thread. Suitable for grinding a wide variety of metals including ferrous and non-ferrous materials.

Installation Notes

Mounting and use of grinding wheels should follow ANSI B7.1 safety standards and all applicable tool manufacturer guidelines. Always inspect the wheel for cracks or damage before mounting, and never exceed the maximum RPM rating marked on the wheel. Ensure the grinder guard is properly installed and in place before operation. Wear appropriate PPE including eye protection and gloves when performing grinding work.
