3.2.2 MTECB
THREAD MILLING DC TP APMX OAL DCONMS

15°

MTECB (Mill Thread Endmills Carbide Bore) Family - solid carbide thread mills with coolant
hole, recommended for internal thread milling in blind holes and can also be used for
production of external thread milling.

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.
MTECB endmills are available with cutting diameters from 3.1 mm up to
20 mm by metric system or from 0.181 inch to 0.75 inch by imperial and United States
customary systems.
This line offers a solution for full profiles for most popular standards.
