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.
Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools.
Standard extension pipe taps are used for internal deep-hole drilling of pipes and pipe fittings. ideal for hard-to-reach-areas in general purpose applications..
Taper chamfers are known as a starter tap. They have a longer chamfer and require a less aggressive cutting action. They are 7 to 10 threads.
