Powermatic OSS10 Oscillating Spindle Sander 1hp, 1-PH - PM1-266

Powermatic OSS10 Oscillating Spindle Sander 1hp, 1-PH - PM1-266

Upgrade your woodworking game with the Powermatic OSS10 Oscillating Spindle Sander. Engineered for precision and ease, this versatile sander is a must-have for woodworking enthusiasts and professionals alike.

Most notable on the OSS10 is the "stay-flat" table design. Instead of featuring a tilting table, like many competitor machines, the OSS10 features a 0-45° tilting spindle. This allows the table and, therefore your material, to stay flat. It also reduces user fatigue over time by supporting the material weight.

Ergonomically-placed controls on the front of the OSS10 make adjustments easy. The large handwheel allows you to set angles, while the dial lets you choose variable oscillation speed. Both speed and angle are displayed on the digital readout.

Comes standard with a 3/4" spindle and sanding sleeve. Also includes five rubber drums with sanding sleeves (sizes 1", 1-1/2", 2", 3", and 4"), as well as four spindles with sanding sleeves (sizes 5/8", 1/2", 3/8", and 1/4").
