NPT Button Dies – Metric OD are designed for cutting accurate National Pipe Taper (NPT) external threads on pipes, fittings, threaded rods and precision components. Featuring a metric outside diameter (OD), these round button dies provide reliable thread cutting performance for engineering, plumbing, hydraulic, pneumatic and maintenance applications. Manufactured from high-quality tool steel or HSS (depending on the product specification), they are suitable for producing new tapered pipe threads or restoring damaged external NPT threads with accuracy and consistency. Available in a range of NPT sizes, these button dies are ideal for professional workshops and industrial use.
