NPT Thread Mills

NPT Thread Mills

National Pipe Thread Taper (NPT) is a American standard for tapered threads used on threaded pipes and fittings, popular in the oil and gas industry. NPT and NPTF hand taps produce a taper thread form whose diameter increases or decreases along the length of the thread.


Carbide thread milling produces a stronger than machine tapping, reduces cycle times and eliminate the risk of scrapping jobs due to tool failure.  Thread milling is highly recommended over tapping for stainless steel and exotic materials, especially in offshore and subsea engineering. Vardex NPT thread mills can be used for internal or external threads using the same thread mill. Please click on the link opposite to use the GENius thread milling programme to select the optimum tool for your application.  Order online today for next day delivery.
