Countersink Bits – More to Them Than You Might Think ...
Countersink Bits – More to Them Than You Might Think ...

Most countersinks are held with setscrews. One setscrew, as it’s tightened, causes the countersink to push against one side of the drill bit, forming a small offset opening. Or if the setscrew falls into the flute of the bit, it can move the countersink position when tightened. With two setscrews you can secure the bit in a more centered position.
