It's incredible, the time you'd save if you didn't have to switch out your drill bit every time you switched from a bolt to a screw in. With the Duo Star Bit, that time wasted is thing of the past. You won’t have to change out your impact bit when you use the Duo Star so dropping those pesky things or finding them in your pockets later won’t be a problem. This 2-in-1 bit works with both standard 5/16" bolts and the classic T25 screw. So instead of botching that bit-switch and finding stray bits in the washing machine, use the Duo Star to make route-setting as smooth as the route itself.


Attach this bit directly to your impact driver for seamless setting and stripping.


- A patent-pending, dual-tipped bit to prevent changing bits while setting with different bolts
