HRC65 Thread Mill

Precision Full-Profile Threading Solutions for 46–68 HRC Hardened Materials

Product Overview:

SAMHO’s HRC65 Full-Tooth Thread Mills are engineered specifically for the most demanding threading operations in ultra-hard materials. By combining a sub-micron grain carbide core with advanced variable helix geometry, these tools deliver micron-level accuracy for RC (PT/BSPT) tapered pipe threads. Designed for high-performance CNC machining, they excel in dry cutting or MQL environments, ensuring a flawless thread finish even in materials up to HRC 68.

Core Technical Features

Optimized for Ultra-Hard Materials (Up to 68 HRC)

Specialized Sub-Micron Carbide Substrate: Specifically designed for quenched steels, hardened die steels, and high-strength alloys. The ultra-fine grain carbide core provides the perfect balance of hardness and fracture toughness, resisting edge chipping under the intense mechanical loads of high-hardness milling.

Full-Tooth Profile for High-Efficiency One-Pass Threading

Accurate Internal & External Threading: The full-profile cutting edge allows for complete thread formation in a single pass. This significantly reduces cycle times compared to single-point tools and ensures superior thread quality for both larger diameters and deep-hole applications.

Variable Helix Design for Chatter Suppression

Anti-Vibration Geometry: Featuring an unequal helix geometry, this tool dampens harmonic vibrations and chatter. This ensures a stable cutting process, resulting in improved surface finishes, better dimensional consistency, and a 20–30% extension in tool life—critical when machining hardened metals.

Advanced Nano-Coating Technology

Extreme Heat and Wear Resistance: Our proprietary nano-coating increases thermal stability and surface hardness. This enables stable performance during high-speed dry cutting or in low-lubrication (MQL) environments, acting as a thermal shield for the tool’s cutting edge.

Industry Applications

• Hydraulic & Pneumatic Systems: Perfect for processing RC (PT) tapered pipe threads in high-pressure fittings and valve bodies.

• Die & Mold Industry: Essential for threading hardened mold bases and inserts (HRC 50+) without the need for additional heat treatment.

• Aerospace & Energy: Precision threading for high-strength fasteners and high-pressure containers where thread integrity is a safety-critical requirement.
