Print Files - Fingerboard Countersinking Collet
$7.00
This is a collet designed to be used with a 1/8” shank conical burr. It acts as both a depth stop and an adaptor to chuck the burr in a drill. It prevents the burr from going through the deck and makes sure your countersinks are consistent and even.
The burr that I use is can be found at McMaster Carr: https://www.mcmaster.com/8175A48/
