The Premium Electrician's 3/8-Inch Hex Step Bit Set 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 straight flutes help pull the step bit through the material for clean cuts. The aluminum titanium nitride coating is 10 times more durable than steamed black oxide for longer bit life. The durable 3/8-Inch hex shank provides a firm, positive grip. 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.
