HFF – Fine Finishing
For finish turning, producing smooth, accurate surfaces. Very good 
chip control, especially at low depths of cut.
HKR – Flat Top
Flat top geometry for machining cast iron. For finishing and 
roughing applications.
HMR – Light to Medium Roughing
For light to medium roughing of steels, difficult-to-machine high-
alloy titanium, and aluminum materials. High strength to deal with 
heavy chip deformation.
HRH – Roughing Heavy
For medium-duty to roughing. Outstanding chip control. High edge 
strength for interrupted cuts, forging skin, or scale. Preferred for 
all cast iron, such as gray, malleable, and nodular.
HUR – Universal Roughing
Roughing geometry, with smooth chip forming and improved 
coolant flow for increased tool life. Positive geometry reduces 
cutting forces, and improves depth-of-cut notching resistance. 
Ideally suited for stainless steel applications, and for smooth 
machining of steel.
HFP – Finishing Positive (Single-Sided)
For finishing to medium turning operations, with optimal chip 
control over a wide range of cutting conditions and workpiece 
materials.
HML – Medium Light
For finishing to medium machining, with a negative, 
stable cutting edge.
HMS – Medium High-Temp
For medium machining in high-temp materials. Utilizes a micro-
finished edge preparation to increase edge toughness. 
HUF – Ultra-Fine Finishing
For finishing, with a positive cutting edge for reduced cutting 
forces and superior surface quality. 
CCET – Finishing Positive (Single-Sided)
For finishing turning operations, with optimal chip control over a 
wide range of cutting conditions and workpiece materials. 
HFS – Finishing High-Temp
For finishing applications. Ground periphery with positive cutting 
edge. Ideally suited for high-temp alloys. Micro-finished edge on 
the ground periphery adds just a slight hone for improved edge 
integrity and reliability. 
HMP – Medium Positive (Single-Sided)
For medium to rough turning, with reduced cutting forces and 
improved chip control for high feedrates. Suitable for high metal 
removal rates. 
HMU – Medium Universal
A medium universal geometry with a soft cutting action due to its 
positive geometry. Has a versatile application range, and is suited 
for turning unstable components and for boring applications. 
HUM – Universal Medium
For medium-duty turning operations. Soft-cutting chip breaker. 
Used in applications producing varying chip sections, such as 
profile or copy turning. Good dimensional accuracy. For soft steel 
materials and stainless steels.
