Subject [PC8100 Series] Turning Inserts for Hard-to-cut Materials Registered 2016-06-16

KORLOY has launched high performance PVD coated turning inserts for hard-to-cut materials such as heat resistant alloy and 
stainless steel.

Heat resistant alloy(Inconel, etc.) causes high cutting force and temperature on cutting edges when being operated resulting 
from its properties of high strength at high temperature and low heat conductivity. In addition, it accompanies chipping, 
breakage or notch wear in accordance with depth of cut due to thermal shock and work hardening. Thus, it is so important to 
select the most proper chip beaker and grade depending on your cutting velocity and cutting length and the other factors.

PC8105 (S05) is a grade used for finishing heat resistant alloy and stainless steel with its characteristics of wear resistance in 
continuous operation at high speed and high temperature.
PC8110 (S10) is an universal grade used for medium cutting to finish of heat resistant alloy and stainless steel with its 
characteristics of wear resistance and chipping resistance in continuous operation at mid to high speed and high temperature.
PC8115 (S15) is an universal grade used for finish, medium cutting and roughing of heat resistant alloy and stainless steel 
with its characteristics of wear resistance and chipping resistance in various machining conditions.

VP chip breakers designed as high-positive minimize cutting heat and prolong tool life when machining hard-to-cut materials 
as well as they perform excellent chip control in various cutting conditions.

The harmony between the PC8100 grade series and VP chip breaker series provides strong resistance to wear and chipping, and 
excellent chip control at high temperature. It is the best solution for turning application of hard-to-cut materials due to its 
high cutting efficiency and stability.
