BaerCoil HSSG Short Machine Tap M 36 x 1.5 STI (oversized for wire thread inserts)

BaerCoil® screw tap are mainly used for thread repair or thread reinforcement in connection with wire thread inserts. With this BaerCoil® short machine tap, a finished thread with oversize can be cut in one operation as a holding thread for wire thread inserts of dimension MF 36 x 1.5. Precise internal thread can thus be cut time-savingly by hand or semi-professionally by machine.
The holding thread for MF 36 x 1.5 thread inserts is also called STI thread (screw thread insert) or STI thread (in English Screw Thread Insert) and has an oversize so that after installation of the thread insert the normal starting thread MF 36 x 1.5 is restored.

Compared to the machine tap, the short machine tap has a short shank. This allows internal thread to be cut by hand without jamming and operated with tap wrenches, ratchets or other holding tools with square drive. The thread can be cut in a pre-drilled core hole. Pre-machining with a taper tap (No. 1) or intermediate tap (No. 2) is not necessary.

With the short chamfer and the straight flutes, the chip is mainly absorbed by the flutes and is not removed during cutting. To prevent the chips from sticking, it is recommended to remove the chips from the grooves with a brush, compressed air or similar after each thread cutting. This form of gating makes the screw tap reliable and universally applicable for both through holes and blind holes.
