ST Series 3 Teeth Solid Carbide Thread Mill for Stainless Steel & Titanium | OEM Factory

Professional Thread Milling Solution for Difficult-to-Machine Materials

The ST Series 3 Teeth Solid Carbide Thread Mill is specially engineered for machining titanium alloys, stainless steels, heat-resistant alloys, and nickel-based materials.
Equipped with a special anti-adhesion coating and optimized cutting edge geometry, it ensures stable cutting performance, superior wear resistance, and extended tool life even under high-temperature conditions.
Ideal for the aerospace, medical, and precision engineering industries where surface quality and tool reliability are critical.

Key Features

1. Specialized Coating for High-Temperature Alloys – Designed to reduce built-up edge and friction when cutting titanium, Inconel, and stainless steel.

2. Reinforced 3-Teeth Edge Design – Enhances tool rigidity, improves chip evacuation, and minimizes risk of breakage inside the hole.

3. Superior Wear & Chipping Resistance – Guarantees long service life and consistent thread accuracy in high-load machining.

4. Excellent for Tough-to-Machine Materials – Suitable for titanium alloys, nickel-based alloys, Kovar, and non-magnetic stainless steels.

5. Bidirectional Threading Capability – Capable of machining both right-hand and left-hand threads for flexible production needs.

Key Features

• Factory-direct OEM/ODM service available

• Custom coatings and dimensions supported

• Consistent quality with ISO9001-certified production

• Technical support for optimized cutting parameters
