NPT Thread Mills

Carbide Thread Mills for NPT & NPTF Threads from Vardex & YG-1

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. We stock the full range of Vardex NPT/NPTF solid carbide thread mills from Vargus - the market leader in threading technology.



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.
