HRC65 Full Tooth Thread Cutter(UNC, UNF, UNEF)

HRC65 Full-Tooth Thread Milling Cutter (UNC / UNF / UNEF)

High-Precision Threading Solution for Hardened Steels

Engineered for CNC thread milling applications, this full-tooth thread milling cutter is specifically designed to machine American-standard 60° threads — including UNC, UNF, and UNEF — in heat-treated steels up to HRC65. Constructed from ultra-fine grain carbide, this tool delivers outstanding wear resistance, thermal stability, and anti-chipping performance. Ideal for dry or MQL environments.

Optimized for Hardened Materials (HRC46–68)
Built to handle high-strength steels such as tool steel, alloy steel, and mold steel post heat-treatment. Maintains sharp cutting edges and geometric stability even under heavy load and high-frequency operations.

Full-Tooth Geometry — Single-Pass Internal & External Threading
The full-tooth profile allows for one-pass threading of both internal and external features. Compatible with a wide range of UNC/UNF/UNEF pitches, reducing cycle time and increasing precision while eliminating secondary finishing operations.

Dual-Direction Threading — Left & Right-Hand Compatibility
One cutter for both left-hand and right-hand threading simplifies tool management, reduces tool change time, and increases flexibility in complex assemblies or varied setup conditions.

Capable of Machining Large Threads with the Same Pitch
Precision toolpath programming enables this tool to process larger-diameter threads with identical pitch — ideal for custom or oversized components such as structural parts, heavy-duty fasteners, and large mold bases.

Variable Helix Design — Minimized Chatter, Enhanced Finish
An unequal helix angle helps reduce harmonic vibration and chatter during machining. This leads to smoother threads, improved sealing performance, and reduced burr formation.

Ultra-Fine Carbide Substrate — High Hardness & Fracture Resistance
Made with high-toughness micro-grain carbide that balances extreme hardness with excellent chip resistance. Suitable for high-speed, dry-machining applications in demanding materials.

Precision 5-Axis CNC Ground — Consistency in Every Cut
Each cutter is finished using high-precision 5-axis CNC grinding, ensuring exact tooth form, symmetry, and repeatable performance — even in large-scale, high-tolerance production runs.
