TWINCUT 45 Degree “Advantage”
Double Negative/high positive! A contradiction of terms? NO! LMT-USA
has done the seemingly impossible by combining the free cutting
action of a high positive cutting edge with the extreme strength
and stability of a thick, negative insert and double negative
mounting system. The advantages of this type of system over a
standard all positive cutter are many fold.
The actual insert cutting edge is stronger because it has the
support of solid carbide behind it. The cutter body itself is
stronger because it has more material behind the insert, giving
it better support. The negative cutter configuration also stabilizes
the setup by actually pushing the work piece down against the
table instead of trying to pull it out of the jaws (the way an
all positive cutter would). Additionally, the relieved face and
outer diameter make this an excellent choice for low horsepower,
high speed, blind pocketing work. The face and outer diameter
make this an excellent choice for low horsepower, high speed,
blind pocketing work. The face relief enables this tool to plunge
as deep as .100” or take ramp cuts to the full cutter depth
of .281”. Through the use of helical interpolation, we have
actually drilled large diameter holes, ramping in at extremely
high feed rates using very little horsepower.
Adding to the already numerous benefits of this tool is the fact
that this cutter system uses only one sixe of insert over the
entire range of one to six inches in diameter.
