Features and Benefits
NPT (National Pipe Taper) refers to American National Standard Taper Pipe Threads. They are commonly used for general purpose applications and require a sealant.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
Titanium carbonitride (TiCN) is harder and more wear-resistant than TiN. It is commonly used on stainless steels, cast iron and aluminum alloys.
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
