Features
1. The service life of the welding PCD/PCBN internal 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 internal grooving tool can reach 3 micrometers.
3. The PCD/PCBN internal grooving tool features small vibration of the blade. 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 internal grooving tools of various specifications according to the need of our customers.

Application
The PCD internal grooving tool is used to groove and cut various materials including copper, aluminum, copper alloy, aluminum alloy, tungsten carbide and nonmetal work pieces. For example, it can be used to process aluminum alloy piston.
The PCBN internal grooving tool is used to groove and cut hardened steel, hard cast iron, grey cast iron and iron series metal work pieces.
