hrc65 3-tooth thread mill

Engineered for high-speed CNC applications, the SAMHO HRC65 Metric Series is the ultimate solution for threading heat-treated materials. Featuring a full-tooth profile for one-pass thread generation and the latest AlTiN nano-coating, these solid carbide cutters deliver exceptional dimensional accuracy and wear resistance in mold steels (H13, S136, SKD61) up to 65HRC.

One-Pass Efficiency: Full-form profile generates complete threads in a single CNC cycle.

Extreme Hardness: Purpose-built for hardened steels from HRC46 to HRC68.

Vibration Control: Variable helix geometry suppresses chatter for superior thread finishes.

Precision Manufacturing: 5-axis CNC ground with tolerances held to ±0.01 mm.

In the competitive world of mold and die manufacturing, reducing cycle time without sacrificing thread accuracy is critical. The SAMHO HRC65 Full-Tooth Metric Series is designed to replace traditional multi-pass threading, offering a faster, more stable solution for internal and external threading in the toughest materials.

Advanced Technical Features

Full-Profile Design for One-Pass Thread Forming
Unlike standard thread mills that require multiple passes, our Full-Tooth design generates the thread in a single pass:
- Maximum Efficiency: Drastically reduces machining time per hole
- Improved Form Accuracy: Perfect metric thread geometry with reduced tool pressure
- High Consistency: Ideal for batch production of large-diameter or deep metric threads
Engineered for Hardened Materials (HRC46–68)
Crafted from premium sub-micron carbide with advanced AlTiN nano-coating, optimized for heat-treated H13, S136, D2, and SKD61 mold steels
Variable Helix Geometry for Vibration Suppression
Unequal helix angles reduce harmonic vibrations and chatter:
- Cleaner Thread Profiles: Eliminates burrs and surface defects
- Enhanced Stability: Maintains smooth finish at higher feed rates
- Longer Tool Life: Protects cutting edge from oxidation and thermal breakdown
5-Axis CNC Precision with ±0.01 mm Tolerance
Ensures perfect tooth symmetry and repeatable micron-level accuracy, essential for go/no-go gauge compliance

Versatile Application Range

Standard & Fine Pitch: Covers Metric Coarse and Metric Fine threads
Dual-Direction Milling: Supports both Right-Hand (RH) and Left-Hand (LH) threading
Industries: Automotive, aerospace, high-precision mold manufacturing, and industrial equipment

Professional Usage Recommendations

Cooling Strategy: Optimized for dry machining or MQL (Minimum Quantity Lubrication); AlTiN coating resists heat and material adhesion
Setup: Use high-precision hydraulic or shrink-fit tool holders for maximum rigidity
Path Control: Helical interpolation recommended for larger diameters; full-tooth profile maintains thread pitch
