Drill-Bit Countersinks with Drill Bit
These countersinks come attached to a high-speed steel jobbers’ bit for drilling and countersinking at the same time. They have a hex shank that fits in all quick-change and standard drill chucks. The bit is held in place with a set screw and can be adjusted up to 1” for different screw lengths. The 82° countersink angle is compatible with the profile of flat- and oval-head inch screws.
