We pursue the endless possibilities of our products
and strive to meet your needs.

Sanyo Tool was founded in 1964, and has attracted customers in a wide range of fields including automotive, aviation, and construction. Since our founding, we have fostered a deep-seated sense of trust in all aspects of our tungsten carbide and diamond cutting, grinding, and machining tools, from design and development through manufacturing.

No matter how good the tooling machine is, if the cutting tool is not precise, it won’t turn out quality products. From the beginning, our motto has been “Products should be made from the heart”, and we strive to deliver quality products that incorporate the ideals of Precision, Durability, and Cost Performance.

Automation has progressed beyond NC and MC, into the stage of FMS, and in an industry where demands for precision and quality of the tools are extremely strict, Sanyo Tool has maintained a superb reputation among our customers.

We constantly endeavor to upgrade our equipment and further refine our skills, in order to ensure the continued trust and meet the expectations of our customers.
