Column5: |
Rake Angle
“-” = Neutral Rake Angle
P = 5 Degree Positive Rake Angle. Recommended
for non-ferrous or gummy materials, like 1018 steel
or 318 stainless. By producing an insert form with
a positive shearing action, a freer cut is produced,
providing for lower horsepower consumption and
less application sensitivity.
C = Cam Ground - Good insert form recommended
for harder workpieces, including high
temperature alloys,M2 and D2. By
“Rounding”the relief of the form of the insert,
less chipping and cracking occurs as the insert
becomes stronger due to greater mass behind
the cutting edge of the insert. |

Column 6: |
Coating
“-” = Uncoated
C = TiN - General purpose, ‘Gold’ coating.
Recommended for straightforward applications
where adequate flood coolant is available.
Y = TiCN - General purpose, ‘Blue Grey’ coating. Highly
recommended for flood and coolant through
applications and slightly harder than TiN coating.
Z = Futura / TiAlN - “Violet” color high heat coating.
Recommended for cutting in abrasive and difficult
to machine materials. Harder yet than TiCN, this
coating works best in applications where high heat
is generated in the cut. Otherwise, we recommend
TiCN coating.
X = Hard Lube - “Dark Grey” color coating for high
heat applications. Recommended for dry cutting
conditions in tough materials and where long chips
are generated.
V = X treme - “Violet-Grey” color coating that is the
hardest coating available. Recommended for high heat,
dry cutting conditions in tough materials. |
