PARTING

JT-Type J-Type
Based on the J-type chipformer with a • First choice for soft materials, parting tubes,
T-land reinforced frontal cutting edge. small diameters and thin-walled parts
• Provides a solution for the intermediate range • Cutting edge with positive rake
between the strong and negative C-type configuration • Low-to-medium feed
and the positive edged J-type chipformer. W insert

• Can be used on a wide range of materials. f ≈ 26 [mm/rev]

• Same manner as the J-type, but it can be used
at higher feeds due to its reinforced edge.
