MTECZ (Mill Thread Endmills Carbide Bore) - these are solid carbide thread mills with
internal coolant holes directed to the cutting edges along the flutes. The endmills should be
used on machines with coolant through the spindle, for applications of through hole, where
the tools with frontal cooling holes (MTECB) are inefficient. MTECZ also can be used for
production internal thread in blind holes and for external thread milling.
The coolant holes improve tool life in all thread milling applications. The coolant stream
flushes the chips from the cutting very efficiently, particularly in soft materials (stainless steel
and high-temp alloys) where the chips tend to be re-cut and stick to the machined area.
MTECZ endmills are available with cutting diameters from 7.6 mm up to 16 mm by metric
system or from 0.394 inch to 0.63 inch by imperial and United States customary systems.
This product line offers a solution for full profiles for most popular thread standards.
