NPTF 30° Helical Thread Mill
Engineered for precision and performance, our NPTF 30° Helical Thread Mills feature a high helix angle that reduces side cutting pressure and promotes smooth, controlled thread milling. Designed for full-profile, crest cutting, these tools produce tight, leak-free NPTF threads that meet dry seal standards. Made from premium submicron grade carbide, they offer exceptional strength and wear resistance. An optional AlTiN+ coating enhances heat resistance and enables higher cutting speeds, making these thread mills ideal for demanding applications where accuracy and durability are critical.
