PRODUCT DETAILS
The GT Series 3 Teeth Solid Carbide Thread Mill is a universal solution for thread milling across multiple materials such as 45# steel, stainless steel, P20, and cast iron.
With a high-performance coating and reinforced cutting-edge geometry, this tool ensures long tool life, excellent wear resistance, and stable performance under demanding machining conditions.
Its 3-flute design improves chip evacuation and reduces vibration, minimizing the risk of tool breakage inside holes. Suitable for both right-hand and left-hand thread milling, the GT Series provides maximum flexibility for various industrial applications including general machining, mold manufacturing, and component threading.
Universal Coating Design – Optimized for 45# steel, stainless steel, P20, and cast iron.
3 Teeth Geometry – Enhances chip evacuation and machining efficiency.
Anti-Chipping & Long Life – Wear-resistant carbide and advanced edge stability reduce tool failure.
Reduced Breakage Risk – Strong cutting edges prevent tool breakage in deep or narrow holes.
Bidirectional Threading – Capable of machining both right-hand and left-hand threads.
