The Square 6 shoulder milling cutter with trigonal inserts has six
cutting edges with three different insert geometries and three different
pitches, and can be used for general machining operations including face
milling, contouring, plunging, slotting, and square shoulder milling.
The cutter bodies come in a diameters from 1.5" to 6.0", and
are nickel-coated and pre-hardened. The bodies come in coarse pitch for
unstable conditions, normal pitch, and close pitch for strong machines,
cast iron materials, and high metal removal rates. The inserts can be
set to a true 90[degrees] setting angle. The inserts lock into place
with a center screw placed in the same direction as the cutting forces.
All inserts can be indexed two-by-three times to offer six cutting
edges. There are three insert geometries available, including ME09 for
stainless steel, M13 for steel and cast iron, and MD15 for harder
materials and high cutting speeds. Each of the insert styles feature two
different corner radii. The R0.8 is appropriate for normal conditions,
but the R1.6 can handle tougher cutting applications. Seco Tools
