CVD (Chemical Vapor Deposition) Diamond Coated Drills

The overall carbide is drilled in a process after CVD diamond coating. This is a cost-effective product, but the edge sharpness is affected by the thickness of the coating. In addition, because the carbide part of the base and the hardness of the diamond coating part of the different, this product absorbs the impact of poor energy performance. Anti-chipping performance is also very limited.
