Please note that these are high quality professional standard dies that with correct care and use will give many years of service. Not to be confused with the cheaper and inferior 'market stall' quality tools that are available from some sources and are good for a couple of jobs and completely useless when used with certain materials.

All our taps and dies are manufactured from HSS (High Speed Steel) or HQS (a manufacturers brand name for HSS with improved toughness properties)
We do not stock low grade carbon steel taps and dies.

These dies are suitable for working with a large range of ferrous and non-ferrous metals including stainless steel.

Please note that piano wire in the manufactured state is usually relatively very hard and so if you are cutting threads on this material, we strongly recommend that the material  is annealed (softened) where the thread is to be cut to preserve die life. Failure to anneal the material can lead to rapid dulling of the die cutting teeth and even failure of the die. 
Effective annealing of steel piano wire can usually be achieved by simply heating to cherry red and allowing to cool slowly.
