Use Conditions

P 10(YT15)

Quality Ht for high speed turning and treading operations with medium and small chip section. Can be used for light rough machining of carbon steel and for finishing operations. Discontinued cutting should be avoided.

P 20(YT14)

To be used for turning operations with medium and large chip section on rigid machines. Can be used for finishing operations as well.

P 30(YT5)

Suited for low and medium speed turning operations. Medium and large chip section in little favorable working conditions. This quality is tit for universal applications.

M 10(YW1)
M 20(YW2)

Quality suited for finishing and light rough machining of alloyed and stainless steels in good working conditions. Small and medium chip section.

K 10(YG8A/YG8X)

Quality used for turning hard cast iron and light alloys such as brass, glass, porcelain, very hard hardened steel, tool steel, stainless steel, manganese steel, stellite, etc. Any vibration or stress whatever should be avoided while machining.

K 15(YG6)
K 20(YG8/YG8N)

General use quality, particularly efficient in machining of cast iron, copper, brass, etc..even with discontinued cuttin
