Customer Service: Problem Solved.

Got a machining problem? We’re here to help you.

Welcome to our new interactive website. You can view our videos, do a quick feeds and speeds calculation, read our blog, and join our mailing list to receive our latest information on the manufacturing and use of precision carbide cutting tools.

You’ll hear from us and our customers about troubleshooting, custom tool solutions, new process designs, re-manufacturing, process re-engineering, and state-of-the-art equipment. We will also share the latest developments coming out of our prototyping labs, like the GTS Monroe Edge. Most importantly, you can send us messages about specific problems you want us to help you solve.

We are passionate about what we do. We want to be a helpful resource. We want your input and feedback. Join our online machine tooling community and help us make it a valuable resource for everyone involved.

Sincerely yours,
