Features
1. The service life of welding the PCD/PCBN external grooving tool is 10 to 15 times that of the average tungsten carbide grooving tool and coating grooving tool.
2. The processing precision of the PCD/PCBN external grooving tool can reach 3 micrometers.
3. The PCD/PCBN external grooving tool features small vibration of the tip. It can also avoid the easy breaking of the set screw and the trouble of repeatedly adjusting the blades.
4. We can manufacture welding PCD/PCBN external grooving tool of various specifications according to the need of our customers.

Application
The PCD external grooving tool is used to groove and cut various materials including copper, aluminum, copper alloy, aluminum alloy, tungsten carbide and nonmetal work pieces such as composite material.
The PCBN external grooving tool is used to groove and cut hardened steel, hard cast iron, grey cast iron and iron series metal work pieces.
