MTECS Small Diameter, Short Solid Carbide Thread Mills

The MTECS (Mill Thread Endmills Carbide Short) solid carbide thread mills are used for the production of small internal threads. These thread mills feature a short 3-tooth cutting zone with 3 flutes and a released neck between the cutting zone and the shank.

This unique tool design offers very precise profiles and a high performance IC908 submicron carbide grade with PVD titanium aluminum nitride coating. The very short profile exerts a low force which minimizes tool bending. This facilitates parallel and high thread precision for the entire length.

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.

Features:
● Minimum thread size: M1.4x0.3 (1.1 mm bore diameter)
   up to M20x2.50.
● 2xD and 3xD threading lengths.
● High cutting speeds.
● Short cycle time.
● Low cutting forces due to the short contact
   profile resulting in accurate and parallel thread.
● Prevents oval threads near thin walls.
● No more dealing with broken taps.
● Reliable threading in blind holes.
● Excellent performance on hardened steel,
   high temperature alloys and titanium.
