hardened steels. As there are millions of these
cams produced each year, manufacturers are
eager to reduce machining cycle times to a
minimum. As OEMs need to remain flexible, to
react immediately to the frequently changing
market and when possible - to spend less
money - they prefer to invest in special cutting
tools rather than purchase new machine tools. In
order to minimize cycle time in this area, ISCAR
has developed a revolutionary concept– a single
innovative insert that is able to complete the
entire CAM machining process. The remarkable
TRIDEEP Drill insert is able to complete face turning, internal
rough turning, internal finish turning and
chamfering. The extremely durable, tangentially
clamped insert faces all 4 operations, including
CAM lobe profile, at the highest possible cutting
parameters with equal ease and completes the
CAM machining cycle within a few seconds.
For deep hole drilling in forged camshafts,
ISCAR offers a different approach – a deep drill
with an exchangeable carbide insert.

This new idea brings many advantages to OEMs. It
makes the process much more cost-effective when
compared to using conventional gundrills.

Special SUMOCHAM Step Drill The standard insert is always available in stock,
it has 3 cutting edges and it negates the need
for re-grinding. The insert has a positive pressed
chipformer and serrated cutting edges that
split chips into multiple small segments, which
reduces machining torque (i.e. enables it to work
with higher feeds) and improves chip evacuation.
In addition, a small wiper at the end of the
cutting edge provides a very fine hole surface.

ISCAR's TRIDEEP drilling line (GD-DH…) holds
IT10 tolerance field and covers a range of
Ø16-28 mm. A standard TOGT insert has three
serrated edges that create thin and short chip
segments for smoother cut. These efficient, cost
effective tools are highly recommended for deep
drilling camshaft applications and can be used
on both lathes and dedicated gundrill machines.
The GD-DH drills are available at 10, 15 and 25
drilling lengths to diameter ratios. As tailored
