LMT-Fette is pleased to announce the introduction of
Bohlerit’s new high-speed turning
grade LC215H. This new grade features a highly wear resistant
P10-P15 substrate that is
gradient sintered to provide exceptional edge toughness.
LC215H is a multi-layer MT-CVD
coated grade featuring TiN, TiCN, and Al2O3 for excellent
heat and wear resistance.
With its excellent balance of wear resistance and toughness,
LC215H grade is excellent for
turning of carbon and alloy steels up to 40 Rc. Additionally
LC215H is also LMT’s number
one choice for the turning of tool steel and high-speed
steel. Due to its excellent heat
resistance, LC215H performs exceptionally at cutting
speeds as high as 1500 SFM. LC215H
should be used in applications where LC215B has been
proven to lack wear resistance or
As stated above, LC215H’s primary application is
in the high-speed machining of carbon
and alloy steels, as well as the turning of various tool
steels. However, LC215H performs
exceptionally in any tough steel applications where the
work piece material features alloying
elements such as tungsten, vanadium, chromium, or molybdenum.
exceptional heat resistance as a result of the multi-layer
MT-CVD coating featuring Al2O3.
The primary advantages of LMT-Fette’s new LC215H
are in its unique ability to handle
highheat turning conditions, in difficult turning operations
such as heat-treated work
pieces, high alloy steels and tool steels, or at cutting
speeds in excess of 1000 SFM,
Additionally, the insert toughness, as a result of the
gradient sintered substrate, offers
exceptional versatility. These two features combined
make LC215H the new standard for
turning of difficult steels, and ultra-high-speed turning
of carbon and alloy steel.
