Product information

BAER HSSG Hand Tap Set (3pcs.) non serial form M 2.5 x 0.45

The hand tap set in conical design consists of three taps and enables you to cut a finished thread with significantly reduced risk of breakage. The advantage of three-piece hand taps 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 pilot and intermediate tap (No. 2) have no marking with one or two rings. The taps all have a fully formed thread profile, but the lead lengths differ: The taper tap (No. 1) in form A has a gate length with 6 - 8 threads and the intermediate tap (No. 2) with form D has 3.5 - 5 threads. The finishing tap (No. 3) with form C has a gate length of 2 - 3 threads and can thus cut the deepest usable thread and also enables blind holes to be cut almost to the bottom. The division of work between the three 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 chamfer of the finish tap, the hand tap set can be used reliably and universally for through holes and blind holes.
As a rule, three-piece hand taps- sets are used for regular threads with coarse pitch, as the thread profile area is larger than for fine threads and the force effects on the taps are greater.
