Frequently Asked Questions
Do you produce custom-size cutting tools?
Yes — send us a drawing or sample and we'll manufacture cutting tools in your required dimensions, geometry and coating. Standard lead time is 7-14 days.
Which coatings do you apply?
We offer TiN, TiAlN, AlTiN, TiCN and diamond-like (DLC) coatings. We recommend the right coating based on the workpiece material.
Is there a minimum order quantity?
No MOQ on standard products. For custom tools, pricing scales with quantity; single-piece production is also available.
Do you ship internationally?
Yes — we regularly export to 25+ countries, primarily Europe, China, Japan and Taiwan. We manage shipping and customs.
Can you re-coat used tools?
Yes — we can re-grind and re-coat your used tools to restore performance close to original specifications.
