PCD Turning Tools are high hardness, strong thermal conductivity and good wear resistance of diamond can obtain highmachining precision and machining efficiency in high speed cutting.

The high hardness of diamond is combined with the toughness of steel or alloy, and the performanceof PCD/PCBN tool is greatly improved with special treatment.

   The advantages of PCD/CBN super hard cutting tool have excellent effect on turning ream and milling.


1. The PCD or PCBN Turning Tool can cut the material from different direction.
2. The PCD or PCBN turning tool can realize fast speed turning, hard material turning, and dry turning.
3. According to the need of our customers, we can design and manufacture the diamond turning tool with different specifications, by changing the sizes of the cutter arbor, rake angle, clearance angle, tool cutting edge angle, tool minor cutting edge angle, nose angle, cutting edge form and the width of the chamfering.

Flexible in order quantity:

Samples can be provided before mass production, and MOQ can be discussed accordingly.
