We think the SIOUX Signature Series Random Orbital Sanders are the most comfortable on the market!  They have been designed with the latest ergonomic features for maximum operator comfort.

• 12,000 rpm state-of-the-art motor.
• The universal grip is COMPLETELY ADJUSTABLE and can be indexed in any one of 24 positions - allowing a perfect fit for any size hand. Perfect for right handed or left handed operators with small, medium, or large hands!
• The power lever has been designed with a contour to fit along the muscle at the base of the thumb - power is engaged when the hand is in a normal resting position.
• The rugged 12,000 rpm motor features dual vibration dampers and a one piece precision machined counterbalance enabling the tool to deliver the power you need while significantly reducing vibration.
• Available in six different configurations - you choose the pad size you need (either 5" or 6") and the orbit size (3/32"-fine,    3/16"-standard  or,    3/8"-coarse)
• Manufactured by Sioux Tools (a division of Snap-On®)
