3M 7000045789 Rubber Cushion Polishing Wheel

Product Description

The 3M 7000045789 is a mechanically expandable rubber cushion polishing wheel designed to securely hold coated abrasive bands and belts in place during grinding and finishing operations. Measuring 2 inches in diameter by 1 inch wide with a 1/4-inch arbor, this wheel uses a mechanical expansion mechanism that grips the interior of the abrasive band to prevent slipping under load. It is a component used in conjunction with abrasive band and belt consumables, not a standalone abrasive. Machinists, metalworkers, and fabricators rely on it for consistent contact and controlled material removal on a range of surface finishing tasks.

This rubber cushion wheel is suited for use with 3M Coated Abrasive Bands and Belts in bench-mounted or portable rotary tool applications. Its compact 2-inch by 1-inch profile makes it appropriate for detail work, deburring, blending, and light polishing on metal, wood, and similar materials. It is sold individually and is intended for professional and production environments where reliable abrasive retention is required throughout the service life of the consumable band or belt.

Compatibility

Designed for use with 3M Coated Abrasive Bands and Belts. Intended for rotary finishing tools and bench-mounted machines that accept a 1/4-inch arbor and accommodate a 2-inch diameter by 1-inch wide contact wheel.

Installation Notes

Installation is performed by machinists or fabricators using standard rotary tool setup procedures. Ensure the tool is fully powered off and unplugged before mounting or removing the wheel. Thread the arbor securely into the tool spindle and confirm the abrasive band is seated evenly over the expanded rubber before resuming operation. Follow the tool and abrasive manufacturer guidelines for maximum operating RPM to avoid wheel failure.
