SPEED AND FEED
Compared to traditional HSS Twist Drill Bits
speed can be increased by 40 - 60 % and feed
by 10 - 20 % without reducing the life time of
the drill bit significantly.

LESS HEAT
TiN is also a poor conductor of heat, so
the heat generated during the drilling
process is diverted into the chips and
coolant and less into the drill bit.
