THREAD MILLING TOOLS USER GUIDE

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
short 3-tooth cutting zone with 3 flutes and a released (1.1 mm bore diameter) up to M20x2.50
neck between the cutting zone and the shank. • 2xD and 3xD threading lengths
• 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
minimizes tool bending. This facilitates parallel and • No more dealing with broken taps
high thread precision for the entire length. • Reliable threading in blind holes
• 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.
