Geometries |

Stellram offers the following geometries for milling. |
|
|
|
|
|
Geometry
-2C |
|
|
–2C
geometry has an open chip breaker that reduces cutting pressure
while maintaining insert strength. –2C is ideal for machining
low carbon steel. |
|
|
|
|
|
Geometry
-3M |
|
|
–3M
has the strength of a flat top “W” insert, however its helical
cutting edge helps to reduce machine power consumption. |
|
|
|
|
|
Geometry
-41 |
|
|
–41
is a general purpose geometry mainly applied to utility ground
inserts. This economical geometry is available with a number
of insert styles for use in all approach angles. The –41 geometry
has a strong cutting edge with a very high positive rake and
can be used with lower feed rates than the –41 geometry. |
|
|
|
|
|
Geometry
-42 |
|
|
–42
is a general purpose geometry for use on most materials. The
positive rake and T-land combine to create a strong cutting
edge. For 90° milling, the –42 geometry is the first choice
for tough operations. It is available on precision ground
insert styles – AP series, SDHT and MPHT in a number of coated
grades. High feed rates are possible with this geometry in
90° and 45° lead angle milling. |
|
|
|
|
|
Geometry
-421 |
|
|
–421
geometry is for medium finishing operations in high temperature
alloys, titanium, stainless steels, and difficult-to-machine
materials. The high positive rake angle prevents built-up
edges in these tough materials. RPHT and SDHT inserts are
available with the –421 geometry for 45° and 0° milling operations.
The –421 is a refinement of the –42 design, but its range
of application is more for finishing and for heat resistant
alloys requiring a sharper cutting edge. |
|
|
|
|
|
Geometry
-43 |
|
|
–43
is a general purpose geometry designed to handle tough, sticky
materials such as stainless steels and high temperature alloys.
It is applied to utility ground inserts with ground wiper
edges for excellent surface finish and closer axial runout
tolerance. ADKT, APKT and MPMT are available with the –43
geometry for use in Stellram’s 90° cutters. Its inclined cutting
edge provides a freer cutting action than the –42 geometry. |
|
|
|
|
|
Geometry
-44 |
|
|
–44
geometry is peripheral ground with a ground facet for producing
the best surface quality in most materials while reducing
cutting pressure and power consumption. |
|
|
|
|
|
Geometry
-441 |
|
|
– 441
geometry is a peripheral ground insert with a sharp cutting
edge for use on aluminum alloys, titanium alloys, copper and
brass. The –441 geometry provides freer cutting in 90° and
45° operations and reduces the “suction effect” associated
with higher helical geometries. |
|
|
|
|
|
Geometry
-45 |
|
|
–45
geometry is designed for roughing and semi-finishing. Available
with a number of grades, –45 geometry allows machining of
a wide range of materials. It is available on utility ground
inserts with ground wiper edges for good surface finishes.
The–45 geometry provides freer cutting in 90° and 45° operations
and reduces the “suction effect” associated with higher helical
geometries. |
|
|
|
|
|
Geometry
-46 |
|
|
 The 46 geometry is a free cutting geometry available in radius inserts for AP..16 style inserts.
Ground facets improve surface finish and peripheral grinding produces an accurate radius form and longer tool life.

Geometry -46 |
|
|
|
|
|
Geometry
-47 |
|
|
–47
geometry has similar cutting applications as the –45 geometry,
with a slightly lower cutting pressure and performs well with
heat resistant alloys. |
|
|
|
|
|
Geometry
-701/
-702 |
|
|
–701
geometry is highly suitable for finishing a wide range of
materials at low feed rates. A very high positive rake allows
a freer cutting action particularly in Aluminum. Titanium
can be finished when the –701 geometry is combined with grade
SFZ. This geometry is available with precision ground Stellram
insert designs. All of the inserts required in the superb
Aerostell™ cutter use the –701 geometry for its excellent
performance on thin-walled components. –702 has a progressive
edge condition allowing machining of harder materials. |
|
|
|
|
|
Geometry -721 |
|
|
 Very high positive rake for free cutting action in aluminum. Excellent for thin-walled components. Available on the
5702VZ cutters. |
|
|
|
|
|
Geometry
-J |
|
|
–J
is a flat top insert with a ground circumference. It is available
with various radius sizes. |
|
|
|
|
|
Geometry
-M |
|
|
–M
has a mini chip breaker allowing for low feed per tooth when
chamfering. |
|
|
|
|
|
Geometry
N |
|
|
–N
is specifically designed for machining steel and iron material.
This profile complements the –701 and –702 geometry series
and expands applications for VAZ cutters. |
|
|
|
|
|
Geometry
-RG..S |
|
|
–RG..S
is designed for finish machining of 3D molds. It is extremely
accurate and provides long tool life. The RG..S is capable of
machining a side wall that is close to 90°.

Geometry
-SN |
|
|
–SN
is our strongest in this range and is ideal for unstable cutting
conditions, long overhangs and very high feed rates. |
|
|
|
|
|
Geometry
...T |
|
|
…T
geometry is for general purpose applications, particularly
in 45° milling operations and is found on a wide range of
Stellram inserts. This design is nearly as tough as flat-top
inserts while providing excellent chip breaking ability. |
|
|
|
|
|
Geometry
-TN |
|
|
–TN
is similar to –SN, but has a smaller edge preparation, which
reduces machine power consumption.
|
|
|
|
|
|
Geometry
...W |
|
|
…W
– Stellram offers a number of flat-top inserts for numerous
milling applications in a wide range of materials. The flat-top
inserts are the best choice for toughness in 90°, 45° and
0° milling. This geometry offers a stronger cutting edge than
a chip-groove insert.
