Klein Premium 3-Piece Electrician's Quick Release Step Bit Set QRSTSPRO

The Premium Electrician's Quick Release Step Bit Kit contains 3 step bits sized 7/8-Inch, 1-1/8-Inch, and 1-3/8-Inch for creating hole cutouts in panels and j-boxes to accommodate most commonly used 1/2-Inch, 3/4-Inch, and 1-Inch conduit. Dual Spiral Flutes help pull the step bit through the material for faster cutting. The aluminum titanium nitride coating is 10 times more durable than steamed black oxide for longer bit life. Impact rated, the 1/4-Inch hex shank provides a firm, positive grip and allows quick and convenient usage with an impact driver and a drill. The compact, modular case comes with cutting oil and is designed to nest neatly within MODbox™ toolboxes and on the MODbox™ Case Adapter Side Rail Attachment.
