FEATURES
Features of EHHRE-TH3
- Approximate radius makes much thinner chip than real radius
- Vibration-free peripheral clearance geometry
- Newly developed coating “TH3” for hardened steel machining
Feature 1 : New Cutting Edge Geometry – Approximate radius makes much thinner chip than real radius
Effect : Composite R geometry on bottom cutting edge could create thinner chips than conventional radius geometry (real R), and it enables to reduce cutting force.
Furthermore, by making the bottom edge a high helix shape, it improves the chip flow. And achieves excellent chip discharging performance.
Feature 2 : Peripheral clearance geometry to reduce vibration
■ Vibration-free peripheral clearance geometry
■ Effect to suppress vibration at corner milling

Feature 3 : Newly developed coating “TH3” for hardened steel machining
■ Features and performance
・High hardness coating with excellent wear resistance and heat resistance
・Has excellent thermal shock resistance enables to suppress sudden chipping
・Long tool life when cutting high-hardness materials (50HRC or higher) such as hardened steel
■ Target steel grade
・Hardened steel (especially 50HRC or higher), high-speed steel
