Thank you for always using our website.

We are pleased to announce that we will be launching a new user site on February 2, 2026, aimed at improving convenience for our customers.
URL: https://mst-corp-contents.jp/en/

With the opening of the new site, the “Technical Information Download” and “Instruction Manual Videos” that you have been using will no longer be accessible.
All customers, including those who have previously registered as users, will need to complete a new user registration (re-registration).
After registration, please allow 1-2 business days before the site becomes available for use.

We apologize for any inconvenience this may cause and appreciate your understanding and cooperation.

*Note: The “MILL BORE Selection Tool” will continue to be available as before.
