Irwin Hanson NC Plug Tap - High Carbon Steel

The Irwin Hanson NC plug tap in high carbon steel is a hand tap for cutting internal threads in the National Coarse (UNC) thread series. Use it in a tap wrench to thread drilled holes in a range of materials. It is a good choice for general-purpose shop, maintenance, and repair work.

Key Features:

• High carbon steel construction gives the tap a hard cutting edge and good wear resistance for hand tapping.
• NC (National Coarse) thread form is the most common standard thread series for fasteners.
• Plug chamfer has a moderate taper on the first few threads. This makes it easier to start than a bottoming tap and cuts threads close to the bottom of a hole. It is the standard choice for most through holes and for blind holes that have enough depth.
• Hanson quality comes from a brand that has made taps and dies for many years and is trusted by machinists, mechanics, and tradespeople.

Use a suitable cutting fluid and back the tap out regularly to break chips. This gives cleaner threads and longer tap life. Choose the tap that matches the thread size and pitch you need.
