Hand Taps -- A General Guide -- When To Use Which One

Standard Hand Taps

High Speed Steel Hand Taps with straight flutes are designed for general purpose hand tapping or in production machines where ground thread accuracy and performance are required. They are suitable for tapping most materials in through or blind holes. Hand taps retain chips in the flutes during use and work best on materials that produce chips and the swarf breaks easily. They are also known as Straight Flute Taps.

High Speed Steel Left Hand Taps are designed to cut threads with a left hand rotation and are commonly used in applications where left hand studs and fasteners are needed.
