THR QM 3.5*0.6*D4

Description

THR QM 3.5×0.6×D4 micro thread milling cutter is a precision solid carbide thread mill engineered for producing M3.5 × 0.6 fine-pitch internal threads in modern CNC machining operations. Designed for micro threading, precision tapping replacement, and accurate thread profiling, this tool delivers reliable results in small and medium-sized threaded holes where conventional taps may fail.

Manufactured from ultra-fine grain solid carbide with a wear-resistant coating, this micro thread mill provides excellent edge sharpness, heat resistance, and long tool life when machining stainless steel, alloy steel, aluminium, brass, copper, titanium, hardened steel, and engineering plastics. The optimized flute and cutting geometry ensures smooth chip evacuation, reduced cutting forces, and vibration-free threading, even in blind holes or thin-walled parts.

The 3.5 mm thread diameter and 0.6 mm pitch make this tool ideal for automotive components, electronics, medical devices, aerospace micro parts, hydraulic fittings, and precision mechanical assemblies. The D4 shank ensures strong rigidity and secure clamping in CNC tool holders, allowing stable high-speed machining with low run-out.

Unlike traditional taps, the THR QM micro thread mill allows right-hand and left-hand thread cutting, easy adjustment of thread size via CNC programming, and produces clean, burr-free threads with excellent surface finish. It also eliminates the risk of tap breakage inside the hole, reducing scrap and machine downtime in high-value production parts.

This tool is compatible with CNC machining centers, VMCs, high-speed milling machines, and Swiss-type lathes, delivering consistent thread quality and accurate pitch in both prototype and mass production.

The THR QM 3.5×0.6×D4 is widely used by CNC cutting tools manufacturers, industrial cutting tools suppliers, and precision machining workshops that demand high-accuracy thread milling, long tool life, and reliable CNC performance.
