The short structural type makes this tap usable by machine and hand.
Compared to the machine tap, the short machine tap has a short shank. This allows you to cut internal thread by hand without jamming and can be operated with tap wrenches, tool ratchets or other holding tools with square drive.
The thread can be cut in a pre-drilled core hole and does not require any preparatory work by a taper tap (n. 1) or intermediate tap (n. 2).
This internal tap clearly offers the price advantage over the hand tap set, as you no longer need two or three screw taps for thread cutting, but only one screw tap. The high time saving in this process also significantly increases efficiency at thread cutting.
 
With the direction of the spiral flute opposite to the cutting direction, these taps are particularly suitable for through holes up to 2.0 times the diameter. Due to the high cutting forces that hit the trapezoidal profile, the screw tap can break on longer threads. For longer threads, we recommend using a multi-part screw tap set

Our taps and dies are produced to the highest quality standards, to ensure precise quality threads. Wide range of hand, machine and rolling taps, dies and tools for cutting professional threads on various materials.

Correct lubrication is important for successful thread cutting and to decrease the wear of taps and dies. We recommend using our lubricants. We also have holding tools for taps and dies: Tap wrenches, die holders, die guides and more
