About Sanding Abrasives

Arbors for Grinding Cones

The threaded head on these arbors holds a grinding cone.

Spiral-Wound Sanding Roll Arbors

The arbor’s shank attaches to hand-held drills and die grinders. Threads on the body hold the sanding roll in place.

Tight-Grip Spiral-Wound Sanding Roll Arbors

The extra-coarse threads on these arbors provide a stronger hold on the sanding roll.

Wheel Arbors

Attach cutoff wheels, grinding wheels, and other abrasive wheels to hand-held drills and die grinders.

Arbors for Sanding Pads for
Internal and Irregular Surfaces

Also known as cross- and square-sanding pad shank adapters, these arbors are required to attach sanding pads for internal and irregular surfaces to hand-held drills and die grinders.

Arbors for Rubber-Cushioned Abrasive Grinding Bits

Thread rubber-cushioned grinding bits onto one of these arbors to use them in drills and die grinders.

Arbors for Threaded-Stud Flap Sanding Wheels

Use flap wheels with a threaded stud in tools that accept a shank.

Arbors for Wheel Brushes

Mount cutoff wheels, grinding wheels, and other abrasive discs to the straight shaft on bench-top motors, grinders, and buffers.

Sanding Sleeve Drums for Threaded Shafts

Install a sanding sleeve on the threaded shaft of a bench or pedestal grinder using one of these drums.

Buffing Wheel Spindles for Hand-Held Power Tools

The shank on these spindles installs directly into grinder collets and drill chucks.

Flap Sanding Wheels with Threaded Stud

The threaded stud allows faster wheel changes but requires the use of an adapter in your tool.
