HT Series Single Tooth Solid Carbide Thread Mill for Alloy Steel, Stainless & Titanium | Factory Direct

The HT Series Single Tooth Solid Carbide Thread Mill is a high-performance universal threading solution for CNC machining of tough materials such as 40Cr, Cr12, SUS stainless steel, P20, S136, 718 mold steel, manganese steel, titanium alloy, and martensitic stainless iron.
Engineered for precision and stability, this tool is capable of machining 60° metric and UNC threads, both internal and external, including tapered and multi-pitch threads. The single-flute design ensures smooth chip evacuation and consistent thread profiles even in deep holes or hard-to-machine materials.

Perfect for manufacturers seeking a versatile carbide thread mill that performs reliably across various metals and machining setups.

Features & Advantages

1. Wide Material Compatibility – Suitable for alloy steel (40Cr, Cr12), stainless steel (SUS), mold steels (P20, 718, S136), titanium alloy, and cast/manganese steels.

2. Universal Threading Capability – Supports 60° metric, UNC, and tapered threads with adjustable pitch.

3. Single Flute Design – Delivers excellent chip evacuation, superior surface finish, and high tool stability.

4. Dual Direction Threading – Can machine both right-hand and left-hand threads with one tool.

5. High Precision & Long Tool Life – Made from ultra-fine grain tungsten carbide for maximum wear resistance and dimensional accuracy.

6. Excellent for Nut and Blind Hole Machining – Perfect for internal thread applications requiring clean entry and exit.

7. Optimized for CNC Centers – Compatible with most modern CNC thread milling toolpaths and controllers.
