Carmex Thread Mills Mini Type - Through Coolant - Metric - M2 x 0.4 - MT7

Carmex Thread Mills Mini Type with Through Coolant is a compact, high-precision solid carbide thread milling cutter designed for small-diameter internal threads. Built for micro-machining applications, it delivers clean M2 x 0.4 threads with reliable coolant delivery and chip control.

• Through coolant bore: internal coolant delivery provides high-pressure coolant through the tool into the pre-hole, aiding cooling and chip evacuation during the threading circle.
• Miniature M2 x 0.4 thread profile: specifically designed for small-diameter internal threads in tight spaces, ideal for precision components.
• MT7 shank: compatible with a wide range of CNC machines, offering solid rigidity for accurate threading.
• Solid carbide construction: exceptional wear resistance and long tool life for demanding micro-thread applications.
• Efficient chip control: the design promotes continuous chip washout as you thread, reducing recutting and improving finish.
• Distinctive edge geometry: feature-rich cutting edge with a purple-tinted appearance visible on the tool tip, signaling a precision-coated-like finish for dependable performance.

This mini thread mill is ideal for engineers and machinists working on compact assemblies—electronics housings, medical devices, and miniature fittings—where precise M2 x 0.4 threads must be produced reliably in confined work envelopes. The through-coolant design supports higher cutting speeds, steadier finishes, and longer tool life by keeping the cutting edge cooler and ensuring consistent chip removal throughout the threading cycle. In practice, it enables smoother thread formation, fewer defects, and quicker setup changes, helping you maintain tight tolerances across small components.
