Regal Cutting Tools - 1-1/4 - 8 UNS 4 Flute H5 Bright Finish High Speed Steel Hand Extension Tap - Plug Chamfer, 12" OAL

Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 threads.

Hand taps are used to cut threads in blind or through holes. They are used by hand or in general purpose machine operations.

Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.

High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
