The Cutting Tools are indispensable to process the parts such as automotive, industries and aircraft. From ceramics to new materials, we offer various kinds of tools with a wide range of line-up.

We offer the various kinds and the shapes to suit your applications.

Ceramics series（Alumina-based Ceramics）HC1・HW2

Application

Semi finishing and/or finishing operation for gray cast iron, engine liner, tube scarfing etc.

Features

This series is mainly composed of high purity alumina with high density and fine grain. It is hard and chemically stable at high temperature.

This series has a good wear resistant at high speed finishing of gray cast iron.

Ceramics series（Alumina TiC-based Ceramics）HC2・HC4・HC6・HC7・ZC7

Application

Semi finishing and/or finishing operation for gray cast iron and ductile. Even for hard turning available.

Features

Adding TIC compound to high purity alumina composition, so that it gains more toughness.

This series keeps the hardness and toughness at high temperature, so that it matches to machining after sintering material.

Ceramics series（Whisker-based ceramics）WA5・WA1

Application

Cutting heat-resistant alloys, such as inconel, waspaloy, etc., and gray cast iron.

Features

This grade has a higher level of wear resistance, toughness and flaking resistance by adding SiC whiskers to major compose of alumina.

Ceramics series（Silicon nitride-based ceramics） SX6・SX7・SX9・SP9

Application

SX6 & SP9 is suited for rough operation in turning and milling for gray cast iron. And SX7 & SX9 is suited for high speed machining for heat-resistant alloy, Inconel.

Features

This grade has a higher level of wear resistance, toughness and flaking resistance by adding SiC whiskers to major compose of alumina.
