Short machine taps allow you to cut a finished thread with just one tool in one step, even by hand. Exact internal thread can be cut by hand or semi-professionally by machine to save time.
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 (No. 1) or intermediate tap (No. 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 also significantly increases the efficiency of thread cutting.
Due to the short chamfer and the straight flutes, chip is mainly absorbed by the flutes and is not removed during cutting. We recommend removing the chip from the flutes with a brush, compressed air or similar after each thread to prevent chip jamming. This chamfer form makes the screw tap reliable and universally applicable for through holes and blind holes.
