The All Purpose Quick Release Step Bit Set contains three commonly used bits sized 1/2-Inch, 3/4-Inch, and 7/8-Inch plus cutting oil. These Dual Spiral Flutes help pull the step bit through the material for faster cutting. The aluminum titanium 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 is designed to nest neatly within MODbox™ toolboxes and on the MODbox™ Case Adapter Side Rail Attachment.
