Product Overview

3-Teeth Solid Carbide Thread End Mills for Aluminum is specifically engineered for high-efficiency, high-precision internal thread milling in aluminum and non-ferrous metals. Featuring an uncoated or ultra-smooth thin-film finish (such as DLC - Diamond-Like Carbon), the cutting edges are extremely sharp and mirror-polished. Combined with the low cutting-force advantages of the 3-teeth design, it completely eliminates the common headaches of metal sticking and Built-Up Edge (BUE) during aluminum machining.

Key Advantages & Technical Features

Razor-Sharp Edge Optimized for Aluminum: Tailored to the soft and gummy nature of aluminum alloys, the cutting edges undergo specialized polishing to deliver effortless shearing and a mirror-like thread surface finish.

Anti-Sticking & Seamless Chip Evacuation: The 3-teeth configuration minimizes tool-workpiece contact, drastically reducing frictional heat. Paired with wide, polished flutes, it ensures chips are evacuated instantly at high RPMs without welding to the tool.

Elimination of Chatter and Deflection: The 3-teeth design paired with a relief neck offers optimal rigidity. It prevents thin-walled aluminum parts from deforming and eliminates tool chatter during deep-hole micro-threading.

Ultimate Tool Versatility: A single 3-teeth thread mill can produce various thread diameters of the same pitch, making it exceptionally efficient for both through-holes and bottoming out blind-holes.

Applications

Perfectly suited for precision threading in aluminum alloys (e.g., 6061, 7075), pure aluminum, die-cast aluminum, copper, brass, magnesium alloys, as well as plastics and other non-ferrous materials.
