BAER HSSG Hand Tap Set (2pcs.) conical UNEF 9/16 x 24
The hand tap set in conical design consists of two taps and allows you to cut a finished thread with significantly reduced risk of breakage. The advantage of two-piece hand tap sets is that the respective parts of a set share the cutting power. In contrast to normal hand taps sets, you can cut a complete thread with each individual screw tap in the conical version. In addition, the taper tap (No. 1) does not have a ring marking. The taps all have a fully formed thread profile, but the gate lengths differ: The taper tap (No. 1) in form A has a gate length with 6 - 8 threads and the finishing tap (No. 3) with form C has a gate of 2 - 3 threads and can therefore cut a deep usable thread and thus also enables blind holes to be cut almost to the bottom. The division of labour between the two screw tap makes it easier to cut a straight and clean thread by hand.
Compared to the machine tap, the hand 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.
Due to the short gate of the finish tap, the hand tap set is reliable and universally applicable for through holes and blind holes.
As a rule, two-piece hand taps- sets are used for fine threads, as the thread profile area is smaller than for coarse threads and the force effects on the taps are smaller.
