BaerCoil Taps

To perform a thread repair or reinforcement with wire thread inserts, you usually need to pre-tap the hole. The correct choice of thread tap ensures that the receiving thread has the right dimensions for the insert. For best results, combine our BaerCoil wire thread inserts with BaerCoil thread taps – all from one source, in proven BAER quality.

Everything you need to know about BaerCoil thread taps

Whether for reinforcement or repair, the basis is a properly prepared internal thread. The hole is drilled and pre-tapped with an oversize tap (STI/EG), as wire inserts do not cut their own thread.

This ensures, for example, that an M4 thread remains M4 after repair. Our BaerCoil taps guarantee safe and precise results.

BaerCoil thread taps (EG/STI) – Our range

As always, BAER offers a wide selection of taps for many thread types – improving pull-out strength, reducing torque, and extending thread life.

Hand taps

Hand taps (cutting taps) with oversize are versatile, usable by hand or machine. They cut in one pass and are available for many standards: M, MF, UNC, UNF, BSW, BSF, BA, BSB, BSC, G, NPT, as well as 8-UN and automotive applications.

Machine taps

Machine taps are ideal for professionals and series production. Available in geometries for blind holes and through holes, covering M, MF, UNC, UNF.

Combination taps

Combination taps cut the oversize thread directly in the damaged hole, saving a pre-drilling step. Available for metric M and spark plug threads.

Thread formers

Our thread formers in HSSE-TiN displace material instead of cutting, creating smooth surfaces and stronger threads. Available for many metric sizes M.
