An adapter that lets you use your own 6.35 mm hex shank pilot bits or metal drills while a step driver bit stays attached to the power tool.
- Use hex shank pilot bits and metal drills without removing the step bit from the power tool.
- Saves the trouble of changing bits and speeds up screw driving.
- Also fits commercially available #1 and #2 step bits (body diameter 4.4-5.0 mm only).
- Available in three colors.
