For plumbers and heating engineers, their BSP dies deliver clean threads on pipe work, whilst their UNC and UNF dies cater to automotive and machinery applications requiring imperial threads.

Available in both individual dies and comprehensive die sets, Sirius products are compatible with standard die stocks and holders, integrating seamlessly into your existing toolkit. Their button dies feature adjustable cutting for achieving precise thread fits on critical assemblies.

Frequently Asked Questions

Are Sirius dies suitable for stainless steel?

Yes, Sirius HSS dies are designed to cut threads in stainless steel, though proper cutting fluid should be used to extend tool life and ensure clean thread formation. For extensive stainless work, consider their cobalt-enhanced variants where available.

What's the difference between button dies and circular split dies?

Button dies (also called round adjustable dies) can be slightly opened or closed to adjust thread fit, making them ideal for precision work. Circular split dies have a fixed size and are typically more economical for standard threading applications.

How do I choose the correct die size?

Select a die that matches both the thread diameter and pitch required. For metric threads, this is shown as M8 x 1.25, for example. Always verify the threading standard (metric, BSP, UNC, etc.) matches your application requirements.
