Taper
Drill Countersink with Stop Collar
1) Tapered drill bit is precisely machined from
High Speed Steel and as such is likely to stay
sharp some ten times longer than similar bits
made from carbon steel.
2) Countersink/Counterbore is machined from high
carbon steel, features four very sharp cutting
flutes for precise and tear free boring and is
adjustable along the length of the drill bit by
means of two set screws.
3) Stop Collar that is adjustable by means of
two set screws. By adjusting the stop collar you
are able to control the counterbore depth. When
counterboring and plugging is not desired, you
are also able to produce a perfect countersink
by setting the stop collar just behind the
cutting flutes.
4) Hex Shank are available on request.
5) Drill Bits Set are available on request.
