Product Description
1 1/2" metric fine and extra fine high speed steel round dies for cutting new external metric threads.
These UK made HSS circular dies are suitable for producing fine-pitch external threads on shafts, studs, bolts and engineering components. Metric fine threads have a smaller pitch than the standard metric coarse series, providing more threads over the same length.

- Die type: Circular die / round die
- Die outside diameter: 1 1/2"
- Use: Cutting new external threads
- Thread sizes available: M14 through to M20
- Thread pitches available: 1mm, 1.25mm and 1.5mm
- Thread direction: Right hand
- UK made high-quality tooling
