PREMIUM CARBIDE GRADES AND TABLES

We offer a variety of carbide for you to purchase directly from us, which is yet another way we strive to be your preferred go-to resource. We would be happy to discuss your purchase and help you determine the grade of carbide needed. We offer only the highest quality carbide available on the market today. We won’t waste your time with inferior materials. We understand the value of quality and performance, and use these grades to manufacture our own high-performance cutting tools.

The raw material that is used to manufacture your tool is just as important as the design of the tool itself. By using inferior materials, the tool life will be significantly decreased. We will never try to profit by using sub-par materials. We put 100% into every tool and the results speak for themselves.
