DORMER PRAMET HAS THE TOOLS
Dormer Pramet’s family of solid
carbide milling cutters for difficult to
machine materials offers a variety
of options from roughing through to
finishing.
The S2 assortment includes a range
of neck options for deep milling
and multi-flute designs to support
numerous applications in tough
steels, titanium and nickel.
Its differential pitch cutters (S260,
S262, S264), for example, reduce
chatter and offer fewer tool offset
adjustments, providing effective chip
removal at high feed rates.
The trio of cutters - available in
diameters from 3mm-20mm -
feature an optimised cutting-edge
to reduce chipping and prolong
tool life. All have an AlCrN coating
for improved wear and oxidation
resistance.
In addition, the S264 milling cutter
has a robust corner chamfer on
the end teeth to further reduce
chipping and a roughing profile for
greater removal rates. Also, the
S262’s corner radius provides a
more precise finish and optimises
performance, especially in ramping
operations.
Meanwhile, Dormer Pramet’s six
to eight-flute cutters (S225, S226,
S227) feature a high helix angle to
keep the cutting edges constantly
engaged with the work-piece. This
results in clean, efficient machining
and a high-quality surface finish.
Several neck options are available to
support pocket milling, up to 8.8xD,
by preventing contact between the
shank and work-piece, eliminating
the risk of vibration and scouring.
To support general milling
applications, the company’s range of
four-flute cutters (S216, S217, S218,
S219) offer a reach up to 9xD. This
range also features an optimised
cutting-edge design and an AlTiN
coating for high hot hardness and
oxidation resistance. A special edge
treatment provides a smooth and
quiet machining process, further
prolonging tool life.
Finally, an assortment of ball nose
cutters (S229, S231, S233) are
available in 1.5mm-16mm diameters,
offering up to 8.3xD. As well as a
special edge treatment to support
smooth machining, its TiSiN
coating provides improved wear
and oxidation resistance in extreme
cutting conditions.
