石川工具研磨製作所 Product Lineup

Since our founding, we have focused on the reuse of tools and aimed for technology that is half a step ahead of other companies. We have worked on improving technology, introducing the latest machinery, and developing human resources. Currently, we have progressed to not only regrinding cutting tools but also manufacturing special tools, supplying tools to various industries, and receiving high evaluations. We have established a handmade processing system using general-purpose tool grinding machines from our founding days, as well as a precision and complex processing system using CNC tool grinding machines, making us one of the top players in the regrinding industry in Japan. 【Business Activities】 ■ Design and manufacturing of carbide tools ■ Regrinding of various cutting tools *For more details, please refer to our catalog or feel free to contact us.

• End Mills

We are offering a "free test regrinding" so you can try our regrinding services. Please take this opportunity to experience the high quality of our regrinding. ● We perform regrinding as usual, regardless of carbide, high-speed steel, number of blades, or shape. ● We also accept specifications for dimensions and angles. ● You can also try various coatings along with the regrinding. ● We provide dimension recording and attach precision tables after regrinding. ● We will meet the usual delivery times just like regular regrinding.

• Hand polishing and filing

We are particular about quality and precision in our coating films.

• End Mills

S-TiN coating. It demonstrates excellent performance in cutting processes with material hardness of 55 HRC or higher.
