Frequently Asked Questions

How often do shredder knives need to be replaced or sharpened?

Longevity depends on the material being processed, but our tungsten carbide inlaid knives offer significantly extended life over standard blades. We recommend regular inspection and rotation to maximize service life.

Can you manufacture knives for any brand of shredder?

Yes. We offer customized services and can manufacture rotor and stator knives to fit most major shredder brands. Please provide us with a drawing, sample, or machine model for a precise quote.

What is the benefit of a tungsten carbide inlay?

A tungsten carbide inlay provides a much harder and more wear-resistant cutting edge than standard tool steel. This results in a longer blade lifespan, cleaner cuts, and reduced operational costs, especially when processing abrasive materials.
