Straight Shaft Arbors for Abrasive Wheels and Brushes
Mount cutoff wheels, grinding wheels, and other abrasive discs to the straight shaft on bench-top motors, grinders, and buffers. Arbors are also known as mandrels.
Tapered Shaft Arbors for Abrasive Wheels and Brushes
Use these arbors to mount buffing wheels, grinding wheels and other abrasive discs to the tapered shaft on bench-top motors, grinders, and buffers. Arbors are also known as mandrels.
Shafts on the right side of a buffer or grinder rotate the wheel in a counterclockwise direction.
Shafts on the left side of a buffer or grinder rotate the wheel in a clockwise direction.

Adapters for Toolroom Grinding Wheels
Use these adapters to mount toolroom grinding wheels to most surface grinders. Adapters consist of a hub, nut, and lock washer.
Use the optional wrench to tighten or loosen the adapter nut.
The optional puller threads into the adapter and applies pressure to the end of the spindle to pull the adapter off the taper.
