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 taps are suitable for working with a large range of hard and soft ferrous and non-ferrous metals including stainless steel.
