Designed to produce a 2B class of fit (UNC/UNF) or 6H class of fit (Metric)
Spiral point forces the chips ahead of the tap - designed for through hole applications
Suitable for various steels (up to 35Rc) and stainless steel - not recommended for aluminum and other non-ferrous materials
The Titanium nitride (TiN) surface treatment has very low frictional properties and high surface hardness which significantly increases the tap wear resistance
