Hex Shank
Adjustable Countersink with Tapered drill bit
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
2) Hex Shank 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) Countersink Set are available on request.
