Epoch Micro Serie Features & Usages Epoch Micro End Mill

• Micro-TH coating is super-smooth coating developed for micro-tool required higher accuracy. •Micro-TH coating realized higher performance even in micro-tool (under 0.1mm) due to less macro-particle. •The characteristic is the same of conventional TH coating.
