THREAD MILLING DC 3.2.4 MTECQ OAL DCONMS

MTECQ (Mill Thread Endmills Carbide Q) Family - solid carbide thread mills with coolant hole
and reduced neck diameter between the cutting zone and the shank, recommended for
internal deep thread milling and can also be used for external deep thread milling.
This family can machine thread lengths up to 3.2 x DC (thread length = 3.2 x cutting
diameter of endmill).
The coolant holes improve tool life in all thread milling applications. In blind holes where
the chips of especially soft materials (stainless steel and high-temp alloys) tend to be re-cut
and stick to the machined area, the coolant stream coming from the bottom in an upward
direction flushes them out of the hole very efficiently.
MTECQ endmills are available with cutting diameters from 12 mm up to 20 mm. This line
offers a solution for full profiles for ISO standard.
