KOMET KUB Quatron® Continuous Drilling to 3×D
The KOMET KUB Quatron® is supplied as standard
in drilling depths up to 4×D with combination
shank DIN 6536 HE and 6595 and also with ABS 50
connection.
A high overall rigidity and square inserts guarantee
dimensional stability and accurate drilling with the
KOMET KUB Quatron® at high feed speeds.
The four cutting edges on each insert make the
KOMET KUB Quatron® totally economic. The latest
coatings combined with tough, strong substrates
reduce friction and also ensure maximum tool life.
The KUB Quatron® from KOMET®, which has already
been successfully established in extreme technical
situations such as for interrupted cuts, angled castings
and rolling skins, is now available with the new insert
technology 21 system.
BENEFITS for you:
8
High stability and economy by using square inserts.
Free flow of chips and no wear on the tool body
because of the special surface treatment.
Can be used for difficult drilling conditions such as
cast angles, rolling skin or interrupted cut
Excellent bore quality with no withdrawal grooves.
Insert geometry 21:
Consisting of ultra fine grain carbide with highly positive
top rake, clearly reduced cutting edge rounding and a new
type of coating, it has been possible to halve cutting forces
compared to previous versions.
Maximum tool life with four cutting edges made up
of specific substrates and coatings.
Same insert internally and externally same coating,
same locking screw.
Intermediate sizes can be supplied within 4 weeks
e.g. U10 71940 (X 19,4 mm 2×D).
This reduces the stress on machine and on workpiece,
which allows significantly higher cutting parameters and, as
a result, increases in productivity.
