1 4 EPP Series Performance, Reliability Square & Corner Radius End Mills FEATURES Extremely rigid design and thin coating layer provide highly accurate finishes Improved flute design provides exceptional chip evacuation EPP-CR: Four Flute, TH Coated Corner Radius End Mills EPP4: Four Flute, TH Coated Square End Mills EPP3: Three Flute, CS Coated Square End Mills

2 Introduction The EPP Series End Mills are ideal for the high-speed roughing, semi-finishing and finishing of a wide variety of materials, especially from pre-hardened steels (35HRC) to hardened steels. Their rigid design efficiently evacuates chips and provides excellent workpiece finishes. FeatureS 1. TH Coated EPP-CR and EPP4 for -, -Efficiency Machining of Hardened Steels The high hardness and oxidation resistance of the revolutionary TH Coating ensure excellent performance and long tool life in 40-55HRC hardened steels such as H13, D2, and A2 as well as pre-hardened steels. heat resistance makes TH Coated tools suitable for dry cutting. OXIDIZING TEMP (C ) TiN TiAIN TH HARDNESS 2. CS Coated EPP3 for -Efficiency Machining of Carbon and s Nano-crystal technology helps to reduce the friction-resistance of the coating while maintaining the hardness. This reduction in friction decreases tool wear and also makes dry cutting possible. COEFFICIENT OF FRICTION(μ) TiAIN TiN CS HARDNESS 3.
