Overview

• High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials
• 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
• Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes
• They have 3 to 5 threads
• 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.
• 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.
