Frequently Asked Questions

What are the advantages of PCD inserts over carbide?

PCD (Polycrystalline Diamond) inserts offer significantly higher wear resistance, up to 100 times longer tool life, better surface finish, and higher material removal rates—especially in non-ferrous metals like aluminum, copper, and composites.

Can CBN inserts be used for interrupted cuts?

Solid CBN inserts are best for continuous cuts. For interrupted cuts, Tipped CBN inserts (with CBN tip brazed to carbide body) are recommended due to their superior shock resistance.

Do you offer custom tool designs?

Yes, we provide full OEM/ODM services. Share your drawings or application details, and we’ll design and manufacture inserts tailored to your specific needs.

What industries use your cutting tools?

Our tools are widely used in automotive (engine blocks, transmission parts), aerospace (titanium and composite machining), energy (turbine components), and precision engineering sectors.
