Product information

BaerCoil HSSG Tap with pilot nose for spark plugs M 18 x 1.5 STI (oversized for wire thread inserts) - length: 120 mm

BaerCoil® Combi screw tap are mainly used for thread repair in connection with wire thread inserts. With this BaerCoil® tap, the old thread can be cut in one operation, without pre-drilling, into an oversize thread as a holding thread for wire thread inserts of dimension MF 18 x 1.5. Only through holes up to a maximum thread depth of 2 x D can be produced with this.

The holding thread for MF 18 x 1.5 thread inserts is also called STI thread (screw thread insert) or STI thread (Screw Thread Insert) and has an oversize so that the normal starting thread MF 18 x 1.5 is restored after installation of the thread insert.

internal thread can be cut without canting and operated with tap wrenches, ratchets or other holding tools with square drive.
The screw tap is used in pre-cut threads to expand them into holding threads for wire thread inserts. Pre-machining with a core drill bit is not necessary.

This internal tap offers a clear advantage over short machine taps or machine taps, as the work step of core drilling and tool changing is eliminated. The high time saving also significantly increases the efficiency at thread cutting.
With the straight flutes, the chip is mainly absorbed by the chip flutes and is not removed during cutting. To prevent the chips from sticking, it is recommended to remove the chips from the flutes with a brush, compressed air or similar after each thread cutting.
