ST Series Single Flute Solid Carbide Thread Mill for Stainless Steel, Titanium & Nickel Alloy | High Heat Resistance

The ST Series Single Tooth Solid Carbide Thread Mill is specially engineered for stainless steel, titanium alloys, high-temperature alloys, nickel-based alloys, Kovar alloys, and non-magnetic stainless steels.
Designed for aerospace and precision machining applications, the ST Series offers exceptional heat resistance, anti-sticking performance, and superior lubrication during threading of viscous or hard-to-machine materials.

The large core diameter and optimized flute geometry significantly reduce breakage risk during deep hole threading, while the specialized nano coating enhances wear resistance, edge toughness, and tool life.
This series supports both rigST-hand and left-hand threads, ensuring versatility across CNC operations.

Key Features & Advantages

1. Material-Specific Design – Ideal for stainless steel, titanium, nickel, and high-temperature alloys.

2. Superior Heat & Wear Resistance – Special coating provides outstanding performance under high cutting temperatures.

3. Anti-Adhesion Geometry – Smooth cutting with excellent chip evacuation, minimizing built-up edge.

4. Large Core Diameter – Enhances rigidity and reduces risk of tool breakage inside holes.

5. High Lubricity Surface – Improves cutting stability and surface finish in sticky materials.

6. Right & Left-Hand Threading – Supports both thread directions with one tool.

7. Long Tool Life – Fine-grain tungsten carbide substrate ensures durability and edge sharpness.

8. Precision Machining Ready – Compatible with all major CNC thread milling paths and software.
