ดอกสว่านหัวหกเหลี่ยม

The hex shank fits my drill chuck way tighter than the round ones I had before, no slipping at all. Made clean countersinks in a batch of cabinet hinges and every screw sat flush.

Countersunk a whole deck of screws this weekend and every single hole came out clean, no wobble or chatter from the hex shank in my driver. The six-sided grip really does stay put in the chuck, so I didn't have to re-tighten mid-project. Exactly what I needed for flush screw heads.

The 6-sided shank locks into my drill chuck without any wobble, so the countersink stays true even on hardwood. Cuts a clean, even taper around the screw hole every time, which is exactly what I needed for flush finishes.
