THREAD MILLING TOOLS

MTECS Small Diameter, Short Solid Carbide Thread Mills

The MTECS (Mill Thread Endmills Carbide Short) Features
solid carbide thread mills are used for the production • Minimum thread size: M1.4x0.3
of small internal threads. These thread mills feature a (.044”0 bore diameter) up to M20x2.50
short 3-tooth cutting zone with 3 flutes and a released • 2xD and 3xD threading lengths
neck between the cutting zone and the shank. • High cutting speeds
This unique tool design offers very precise profiles • Short cycle time
and a high performance IC908 submicron carbide • Low cutting forces due to the short contact profile
grade with PVD titanium aluminum nitride coating. resulting in accurate and parallel thread
The very short profile exerts a low force which • Prevents oval threads near thin walls
• No more dealing with broken taps
minimizes tool bending. This facilitates parallel and • Reliable threading in blind holes
high thread precision for the entire length.
• Excellent performance on hardened steel,
high temperature alloys and titanium

Compared to taps, the SOLIDTHREAD is more accurate,
thread machining is substantially faster and there is
no danger of a broken tap being stuck in the hole.
