HRC65 Three-teeth Thread Cutter(Metric)

HRC65 Three-Tooth Thread Milling Cutter (Metric)

High-Efficiency Threading Solution for Hardened Steel Applications

This high-performance thread milling cutter is engineered specifically for internal and external metric thread milling on hardened steels ranging from HRC46 to HRC68. Constructed from ultra-fine grain carbide and featuring a robust three-flute design, it offers outstanding chip evacuation, rigidity, and precision. Ideal for use on CNC machining centers operating in dry cutting or MQL environments.

Purpose-Built for Hardened Steels (Up to HRC65)
Designed to mill threads in heat-treated mold steels, tool steels, and alloy steels. The tool maintains edge sharpness and structural integrity even under high-frequency, high-load cutting conditions.

Three-Flute Configuration for Superior Chip Evacuation
The open three-tooth layout ensures efficient chip removal and minimizes heat accumulation, especially during deep-thread milling operations. This design reduces tool wear and enhances thermal stability during continuous cuts.

Dual-Direction Threading for Increased Flexibility
Capable of milling both right-hand and left-hand internal and external metric threads, reducing the need for multiple tools and setups. One tool covers a broad range of applications.

Variable Helix Geometry for Vibration Control
The unequal helix angle design suppresses cutting chatter and harmonic vibrations, resulting in smoother finishes and improved thread accuracy—ideal for use in high-precision industries such as mold and aerospace manufacturing.

Ultra-Fine Carbide Substrate for Toughness & Wear Resistance
Manufactured from premium-grade micro-grain carbide, this tool delivers a balanced combination of hardness and fracture resistance—well-suited for high-speed dry threading of hardened materials.

Five-Axis CNC Ground for Precision and Repeatability

Each tool is ground using advanced 5-axis CNC technology to ensure strict dimensional tolerances, perfect tooth symmetry, and exceptional consistency—critical for batch production requiring tight thread tolerances.
