Features and Benefits
NPTF (National Pipe Taper Fuel) refers to Dryseal American National Standard Tapered Pipe Threads. They do not require a sealant due to being formed by metal to metal contact.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
Short projection pipe taps are used for shallow hole applications. They are ideal, for the internal threading of pipes and pipe fittings.
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
