Unibit extension

06 Mar 2005 Unibit extension

I bought two unibit extensions – one from home depot, and the other from Avery. Neither worked due to the small size of the fitting on the end. I actually have not needed a unibit extension, until last night, when drilling the hole for the brake lines to pass through the gear box to the gear leg.

I created my own extension by grinding off the three round parts of the unibit shank, and jamming the unibit into a 9mm socket. This allowed me to extend the unibit as much as I needed.

The grinding on the unibit was minimal, and will not affect the drill chuck’s ability to grip it.
