TOOLING AND WORKHOLDING
· The KM-64 ·
drills include continuously thinned web technol-
ogy designed to reduce thrust requirements during
drilling. They also feature edge preparation that
protects the cutting area and prevents premature
chipping and flaking. A strong corner design
across the range also increases stability and
reduces the forces encountered when exiting the
workpiece, the company says.
The micrograin carbide substrate, along with
the TiAlN coating, is said to offer high wear resis-
tance and increased tool life, while the 140-degree,
split-point geometry provides centering capa-
bilities and low-thrust forces.
The company offers both solid- and coolant-
feed options to improve cutting efficiency and
chip evacuation.
