DC DCONMS THREAD MILLING

60°
MTECI (Mill Thread Endmills Carbide I) solid carbide thread mills for the production of small
internal threads. These thread mills feature a Single-Point cutting head design and a released
neck between the cutting zone and the shank. This family can machine Thread lengths up to
5 x DC (thread length = 5 x cutting diameter of endmill).
MTECI products are recommended for internal deep thread milling and can be used for
external deep thread milling. This family can also machine threads near thin walls.

This unique tool design offers very precise profiles and a high performance. The very short
profile exerts a low force which minimizes tool bending. This facilitates parallel and high
thread precision for the entire length.
MTECI endmills are available with cutting diameters 0.72 mm up to 16 mm. This line offers a
solution for partial profile 60° and full profiles for ISO standards.
