Sioux Tools Introduces Keyless Chucks

The KEY to Saving Time… is NO KEY!


We’ve added keyless chucks to our high-quality drills. Change drill bits in and out with a twist of the hand to save time.


  • 1/2” and 3/8” chucks
  • 2-sleeve design allows safe tightening without using drill power
  • Internal locking mechanism helps keep drill bit tight
  • Hardened jaws for high torque bit holding. (Carbide inserts in 1/2” chuck)
