PCD・Diamond End Mill

Cutting processing of highly fragile materials, such as a hard metal alloy…PCD end mill/diamond coating series that changed an impossibility to a possibility.

PCD End Mill

PCD (polycrystalline diamond) is adopted as a tool material. Many technical elements, such as a special cutting edge, provide the finishing quality and know-how for processing of the new generation and were developed to realize a nano-level finished surface by cutting work.

DIAMOND COATING End Mill

A cemented carbide end mill where the cutting edge surface is coated with diamond crystals. The end mill where the cutting edge can easily be designed and the shape most suitable for machining a hard and fragile material was developed. In addition, various types of technical developments for avoiding the peeling of the diamond coating that protects tools realized commercial products.
