LMT-Fette is pleased to announce the helical-shaped,
extremely free-cutting geometry of
our new WPR-D Helical Ball Nose insert. The new insert
provides long tool life and excellent
surface finishes when machining complex work pieces.
The use of traditional inserts with
straight cutting edges typically results in unequal cutting
forces, as well as increased
vibration, shorter tool life and slower feed rates. The
WPR-D helical cutting edge results in
incremental entry of the cutter and significantly reduces
vibration for a soft, peeling cut.
The WPR-D insert cutting edge is designed to always be
under a load for increased
stability and further reduced vibration.
The new WPR-D Helical Ball Nose inserts are designed
to meet the demands of the growing
segment of high-speed machining in the die and mold market,
on tool steels up to 60 Rc.
The inserts, with their free-cutting action, consistently
proves to be a finishing tool of choice.
Super-fine carbide substrate combined with a unique helical
grind and PVD ALCrN coating
result in a new standard for semi-finishing ball milling
WPR-D Helical Ball Nose
inserts are designed for die and mold materials commonly
such as tools steels P20, H13, A2, and D2. WPR-D helical
inserts can also provide excellent
tool life in softer alloy materials, less than 45 Rc.
With its new enhanced coating, the
LC610Q insert grade is suitable for either wet or dry
The primary advantage of LMT-Fette’s
new WPR-D Helical Ball Nose insert is its ability to
freely, reduce vibration and extend tool life. The WPR-D
insert geometry exhibits a helical
cutting action, providing soft, peeling cutting to the
center of the insert, and in turn reducing
horsepower and increasing insert stability.
