Solid Carbide Thread Mills<br />
For 1/16” thru 2” NPT &<br />
NPTF Taper Pipe<br />
Solid carbide thread mills are<br />
designed to produce internal NPT<br />
and NPTF pipe threads to a close<br />
tolerance on thread dimensions and<br />
limits of size, and with excellent<br />
surface quality on the thread flanks<br />
to consistently achieve tight, leakfree<br />
joints. Emuge’s advanced NPT<br />
and NPTF thread mills are<br />
manufactured with a premium<br />
micro-grain carbide substrate, PVD<br />
coated, and finished ground with<br />
precise cutting geometry to ensure<br />
long tool life, low cycle times, and<br />
superior finished threads in all<br />
materials up to 58 Rc.<br />
Insert Thread<br />
Milling Method<br />
(Gigant-ic)<br />
For 3/4” NPT-API thru 20”<br />
Taper Pipe<br />
Emuge’s indexable partial profile<br />
insert thread mills can produce NPT<br />
and API taper pipe threads with<br />
excellent fit, form, and finish for<br />
thread sizes 3/4"thru 20". Reference<br />
carbide insert table shown in the<br />
Gigant-ic section of this brochure<br />
for selecting proper body/insert<br />
combinations.<br />
Multiple flute design with<br />
precise symmetrical spacing<br />
and constant rake angle<br />
optimizes cutting performance<br />
and thread quality.<br />
Ground with high profile<br />
correction ratio which allows for<br />
enlarged cutter diameter to<br />
eliminate tool deflection and<br />
improve chip removal.<br />
