Rubber Bench & Pedestal Grinder Wheel – Aluminum Oxide

Whitby Abrasives Rubber Bench & Pedestal Grinder Wheels are designed for gentle grinding, deburring, polishing, rust removal, blending, and finishing on metal, steel, aluminum, and other materials. This series is available in 3", 4", and 6" diameters with grit options from 80 to 240, covering everything from initial stock removal to fine surface finishing. The 3" wheel uses a fixed 3/8" arbor; the 4" and 6" wheels feature an adjustable arbor to fit most standard bench and pedestal grinder spindle sizes.

The unique rubber-based composition mixed with aluminum oxide grain delivers effective abrasive action while maintaining a gentle touch on the workpiece. Unlike conventional vitrified grinding wheels, the rubber matrix allows some give during contact, which reduces the risk of distorting part geometry during deburring, minimizes heat buildup, and makes these wheels well-suited for finishing passes, light rust removal, and surface blending where a more aggressive wheel would cause damage.

Compatible with bench grinders and pedestal grinders from Makita, DeWalt, Milwaukee, Bosch, Craftsman, Black+Decker, Tacklife, and other brands with standard spindle configurations. Each wheel is reinforced for structural integrity at operating speeds and provides consistent abrasive performance across its full service life. Suitable for metalworking shops, automotive repair, welding shops, maintenance teams, and hobbyist workshops.

Follow the tool manufacturer's instructions and ANSI B7.1 abrasive wheel safety practices.

Frequently asked questions

Q: What are these grinding wheels for?
A: Fast stock removal, weld grinding, edge beveling, and surface prep on metal and stainless steel.

Q: Can I cut with a grinding wheel?
A: No — use a cut-off wheel for cutting. Grinding wheels are for grinding.

Q: What tool do these fit?
A: Standard angle grinders matching the diameter and arbor listed.

Q: What is a depressed-center wheel?
A: The offset center lets you grind at an angle while keeping the nut clear of the work.
