BAER HSSG Hand Tap Finishing (No. 3) UNC No. 4 x 40
The hand tap finishing tap (No. 3) enables you to cut a finished thread. It is advantageous to shape the thread beforehand with a taper tap (No. 1) or intermediate tap (No. 2) in order to better distribute the cutting power.
The finishing tap (No. 3) can optionally also be used without a pre- or intermediate tap (No. 2) as it already cuts a fully usable thread. However, the short chamfer makes it more difficult to get straight into the hole and the tool life time is reduced compared to using multi-part hand tap sets
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 into a pre-drilled core hole. Due to the short chamfer of the finish tap, it can be used universally for through holes and blind holes.
