This page lists our range of Metric Dies from M2 to M6.

 Other thread forms also available including  Metric fine, BA, UNC, UNF, BSF, BSW, BSP, NPT, Model Engineer - please  e mail us with your requirements.

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.

We also list Die Holders to suit all our 13/16" Diameter Dies

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 complete failure of the die through fractured teeth. 
Effective annealing of steel piano wire can usually be achieved by simply heating to cherry red and allowing to cool slowly.
Please also be aware that commercially manufactured push rods are usually manufactured using a thread rolling process for which undersized rod diameters are used (the process forms a thread major dia larger than the original rod dia) so extending the thread on these rods using a die is difficult. Best results will obtained by making push rods using the correct dia rod diameter (2mm for M2 etc). Our Silver Steel rods, listed here, give excellent results.
