3M 7100024622 Unitized Abrasive Wheel 4 in Aluminum Oxide

Product Description

The 3M 7100024622 is a unitized abrasive wheel from the Standard Abrasives 700 Series, designed for deburring, cleaning, and surface finishing on metal workpieces. Built with aluminum oxide mineral at medium-to-hard density, this wheel delivers the edge durability needed to tackle heavy-duty tasks including punched hole deburring on stainless steel, removal of heavy flashing and medium-sized pits and scratches, and cleaning of heavy scale or weld discoloration. The 4 inch diameter wheel mounts via a 3/8 inch arbor hole using a unitized wheel mandrel, sold separately. It is installed by machinists, fabricators, and metal finishing technicians.

This wheel is suited for mid-sequence and finishing operations on ferrous and non-ferrous metals, including aluminum, stainless steel, and carbon steel. Its open web construction resists loading, making it effective in applications where softer or standard bonded wheels clog quickly. Typical use cases include weld cleanup, light burr removal after punching or drilling, and general surface conditioning in fabrication shops and machine shops. The wheel is rated for both clockwise and counterclockwise rotation, allowing compatibility with a wider range of bench-mounted and handheld rotary tools.

Key Features

• Medium-to-hard density aluminum oxide construction engineered for deburring and heavy-scale removal on hard metals
• Increased edge durability over 600 Series unitized wheels for longer service life in heavier-duty tasks
• Open web design resists loading, extending usable wheel life in metal cleaning and conditioning applications
• Runs clockwise and counterclockwise for greater compatibility with varied rotary tools and machines
• Aluminum oxide mineral suitable for ferrous and non-ferrous metals including aluminum and stainless steel
• 3/8 inch arbor hole attaches via a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with rotary tools and machines that accept a unitized wheel mandrel with a 3/8 inch arbor. Suitable for bench grinders, die grinders, and similar rotary equipment capable of accepting 4 inch diameter unitized wheels.

Installation Notes

Installation should be performed by a qualified metalworking technician or fabricator following the tool manufacturer's specifications. Always power down and disconnect the tool from its energy source before mounting or removing the wheel. Verify that the tool's rated RPM meets or exceeds the wheel's maximum operating speed before use. A unitized wheel mandrel with the correct arbor size is required and is not included with the wheel.
