BAER HSSG Hand Tap Taper (No. 1) UNEF 1/4 x 32
The hand tap taper tap (No. 1) in conical design enables you to pre-cut a thread. The advantage of pre-cutting a thread is that the cutting forces on the subsequent finishing tap (No. 3) are reduced. The screw tap in form A has a gate length of 6 - 8 threads. In contrast to normal taper taps, taper tap (No. 1) in conical design can cut a complete thread profile up to the gate area. Due to the long gate, the screw tap is more suitable for through holes. In addition, the screw tap does not have a ring marking on the tap as is the case with normal taps. In combination with a finishing tap (No. 3) it is 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.
