Positive and Negative Inserts
• Screw-on inserts are the fi rst choice for
I.D. turning of all materials and O.D. turning
on small to medium lathes.
• Suitable for all workpiece materials.
Ceramic Inserts
• Ceramic inserts are a great choice for productive
machining of high-temp alloys.
• Negative rake inserts are also recommended for
the machining of hardened materials and cast irons.
• Available in fl at-top geometries with moulded and
ground peripheries.

Negative Inserts
• Negative style inserts are your fi rst choice for general
machining of all materials on medium to large lathes.
• Negative style inserts offer the best economy for high
metal removal rates.
• Available in fl at-top and chip-control geometries
with both moulded and ground peripheries.
• Suitable for all workpiece materials.
PcBN and PCD Inserts
• PcBN can be used for machining steels with a hardness
higher than 48 HRC.
• PcBN inserts can also be used for productivity improvements
in machining cast irons and high-temp alloys.
• PCD inserts are used for machining non-ferrous materials.
