3M 7100122430 Deburring Wheel Aluminum Oxide Coarse

Product Description

The 3M 7100122430 is an aluminum oxide unitized deburring wheel rated for use in high-speed grinding and surface finishing applications. Built to a density grade of 7 (hard), it delivers consistent stock removal and edge blending on metal workpieces. The wheel measures 3 inches in diameter with a 0.25-inch face width and a 0.375-inch center hole, making it a compact but capable solution for deburring, light grinding, and surface conditioning tasks. A maximum operating speed of 18,100 RPM allows it to run efficiently on a wide range of pneumatic and electric rotary tools. Licensed tradespeople and production grinders rely on this wheel for reliable performance on ferrous and non-ferrous metals.

This unitized deburring wheel is suited for use in both shop and field environments where consistent edge finishing and burr removal are required. Its coarse grade and hard density make it well matched to aggressive deburring passes and light material blending on steel, aluminum, and similar workpieces. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands, giving it broad utility across fabrication and finishing workflows.

Key Features

• Aluminum oxide abrasive material provides consistent cut rate on metal surfaces
• Density 7 hard grade resists compression for aggressive deburring and edge work
• Coarse grade for rapid burr removal and light surface blending
• Rated to 18,100 RPM for compatibility with standard die grinders and inline sanders
• Unitized wheel construction maintains shape and cuts consistently throughout wheel life
• Compact 3-inch diameter fits standard 0.375-inch arbor tooling

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands equipped with a 0.375-inch center hole arbor.

Installation Notes

Mount this wheel only on tools rated at or above 18,100 RPM and confirm the arbor size matches the 0.375-inch center hole before use. Always inspect the wheel for cracks or damage before mounting and follow ANSI B7.1 safety standards for abrasive wheel mounting and operation. Power down and disconnect the tool before installing or removing the wheel. Use appropriate eye protection and guarding per shop safety requirements during operation.
