Product Description
1 1/2" National Pipe Thread high speed steel round dies for cutting new external tapered NPT threads.
These UK made HSS circular dies are suitable for producing new NPT threads on pipe fittings, adapters, connectors and engineering components. NPT uses a tapered 60-degree thread form and is commonly used on American-manufactured hydraulic, pneumatic and fluid-handling equipment.

| Thread Size | TPI | Die Outside Diameter | Thread Form | Material |
|---|---|---|---|---|
| 1/8"-27 NPT | 27 | 1 1/2" | National Pipe Taper | High Speed Steel |
| 1/4"-18 NPT | 18 | 1 1/2" | National Pipe Taper | High Speed Steel |
| 3/8"-18 NPT | 18 | 1 1/2" | National Pipe Taper | High Speed Steel |
For best results, use with the correct 1 1/2" die stock and a suitable thread-cutting lubricant. Begin the die square to the workpiece and periodically reverse it slightly to help break and clear the swarf.
Please note: NPT sizes refer to the nominal pipe size and do not equal the actual measured outside thread diameter.
