In high-hardness material machining, cutting tool performance requirements are extremely demanding. Tools must maintain stable cutting in hardened steel up to HRC65. At the same time, they must deliver excellent wear resistance and precise thread accuracy.
The SAMHO HRC65 RC/PT full-thread end mill is engineered specifically for these conditions. It is designed for efficient thread machining in difficult materials such as hardened steel and high-hardness alloy steels.
This tool series features a high-performance carbide substrate combined with advanced coating technology. This significantly improves resistance to chipping and wear under high temperatures and heavy cutting loads. As a result, tool life is extended and machining stability is improved.
Advanced Technical Features
High-Adhesion Nanocomposite Coating for Extended Tool Life
This tool features a high-adhesion nanocomposite coating developed for machining high-hardness materials. It delivers stable performance even in HRC65 hardened steel applications:
- Excellent Wear Resistance: Reduces tool wear during continuous cutting of hardened steel and extends tool life
- Strong Edge Integrity: Minimizes micro-chipping under heavy loads and interrupted cutting conditions
- High Thermal Stability: Maintains coating adhesion and oxidation resistance at elevated cutting temperatures
Full-Profile Thread Design for Single-Pass Accuracy
Engineered for RC/PT tapered pipe threads, this design ensures precision and reliability in demanding applications:
- Full-Profile Cutting: Produces complete thread geometry in a single pass, eliminating multi-pass errors
