Your Global Craftsman Studio, for You and the World

In the automotive and aircraft industries, demand for leading-edge materials and technologies continues to grow. The Advanced Materials & Tools Business Company applies technological expertise accumulated over years to meet these needs. We supply customers around the world with cemented carbide products, which are essential to parts processing, and sintered parts—key components for engines and transmissions.

Business Summary

Sintered ProductsSintered Products

The Advanced Materials & Tools Business conducts its business in two primary categories; cemented carbide products and sintered parts.
The cemented carbide products department provides an extensive lineup of cutting tools used in processes including lathe turning, milling, and drilling, as well as abrasion-resistant tools and construction tools. The department manufactures these products in Japan and overseas, sells them in global markets, and has a leading share of the Japanese market.
We are also undertaking the recycling of tungsten, a rare metal, and focusing on the recovery of used cemented carbide tools.
In the sintered parts department, we produce sintered parts for automobile engines and transmissions at five locations around the world, helping to meet the growing need to increase fuel efficiency for eco-cars and other vehicles and shift toward the use of electric cars.


Targets and Strategy


In the Advanced Materials & Tools Business, by the early 2020s we aim to garner a world market share of more than 10% for cemented carbide products and attain the top rate of sales in the industry for sintered parts. Targeting the automotive, aircraft and medical industries, which are focus areas for this business, we aim to reinforce our product supply capabilities, as well as our ability to resolve problems. We are also working to increase sales to major customers in various industries. As we expect overseas demand for both cemented carbide products and sintered parts to continue growing, we are aggressively strengthening and expanding our overseas production, technical and sales bases.
