In the field of thread milling for high-hardness materials, tool requirements are extremely demanding. Tools must maintain stable cutting performance in HRC65 hardened steel and other high-strength alloys. At the same time, they must deliver high thread accuracy and long tool life.
The SAMHO HRC65-grade UNC / UNF / UNEF full-thread end mill is specifically engineered to meet these challenges. It features a high-rigidity solid carbide structure, combined with an ultra-fine grain carbide substrate and a high-performance coating system.
Advanced Technical Features
When machining HRC65-hardened steel and other high-hardness alloy steels, thread milling tools must deliver three key performance factors: wear resistance, chip resistance, and stable thread accuracy.
The SAMHO HRC65 UNC / UNF / UNEF full-profile thread end mill is specifically engineered for these demanding applications. It is designed for stable performance in hardened steels and precision thread forming under high cutting loads.
High-Performance Coating for Extended Tool Life
This tool uses a coating system developed for high-hardness machining environments. It provides strong surface hardness and thermal stability during cutting.
- High wear resistance: Maintains cutting edge stability during continuous thread milling in HRC65 hardened steel and high-strength alloys
- Strong anti-chipping performance: The coating bonds tightly to the carbide substrate, reducing delamination under heavy load and interrupted cutting
- Stable performance in harsh conditions: Suitable for deep thread milling, full-profile threading, and high-feed applications in hardened materials
High-Rigidity Geometry for Precision Thread Forming
The tool geometry is optimized for UNC, UNF, and UNEF full-profile thread standards. It is designed to ensure accuracy and consistency in both internal and external threading.
- Stable thread profile generation: Produces consistent thread geometry in high-precision applications
- Wide material adaptability: Suitable for mold steels, tool steels, and high-strength structural components
- Improved thread accuracy: Enhances pitch consistency and surface finish while reducing secondary finishing operations
Efficient Cutting and Low Heat Generation Design
The cutting edge and flute design are optimized for stable chip evacuation and reduced thermal load during machining.
- Lower cutting temperature: Reduces heat buildup when machining hardened steels
- Efficient chip evacuation: Prevents chip accumulation and reduces surface damage risk
- Stable machining process: Suitable for dry cutting and MQL (minimum quantity lubrication) environments
Ultra-Fine Grain Carbide and Precision Grinding Process
Manufactured from ultra-fine grain carbide with high-precision thread grinding technology to ensure consistent performance in demanding applications.
- High dimensional consistency: Ensures stable thread accuracy in batch production and automated machining systems
- Improved fracture resistance: Performs reliably in both continuous and interrupted cutting up to HRC65 materials
- Extended tool life: Reduces tool change frequency and lowers cost per part in production environments
Versatile Application Range
This tool series is widely used in the following machining environments:
- Internal and external thread machining in mold steels and quenched steels
- Thread milling of high-hardness steel components (HRC50–65)
- Precision thread forming of high-strength alloy steel parts
