Izawa Technol Laboratory CO., LTD, in Utsunomiya-city, Tochigi-prefecture, pursues the finest quality in its production of carbide hob cutters, carbide formed cutters and industrial fastener tools and more.

The reason why the carbide hob was originally adopted by the camera industry was because compared with the high-speed steel hob, the carbide hob had a greatly extended tool life. This fact alone greatly improved the operating rate and production efficiency of the machines. The carbide material is considered to be brittle compared to high-speed steel, however due to the fact that the processing machines used for small gears were extremely precise and with little vibration, the combination worked well, with no failure in the process. Simply said, the carbide hobs were ideal for the processing of small gears.
