THREAD MILLING TOOLS

MTECS Small Diameter, Short Solid Carbide Thread Mills

The MTECS (Mill Thread Endmills Carbide Short) solid This unique tool design offers very precise profiles and
carbide thread mills are used for the production of small a high performance IC908 submicron carbide grade
internal threads. These thread mills feature with PVD titanium aluminum nitride coating.
a short 3-tooth cutting zone with 3 flutes and The very short profile exerts a low force which minimizes
a released neck between the cutting zone and tool bending. This facilitates parallel and
the shank. 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.

Thread Mill vs. Tap

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
