Baercoil STI Thread Taps
BaerCoil® Taps
The BaerCoil® tap dimensions are different in diameter than normal taps. They have a larger diameter than standard taps in order to hold the wire thread insert while maintaining the same dimension. STI- or EG taps are made according to exact standards and in high-performance high-speed steel (HSS or HSSE).
If a BaerCoil® thread insert is installed in a correctly cut receiving thread, the required thread tolerance for the installed screw is achieved.
Compatibility Important: BaerCoil® taps are compatible with wire thread inserts and taps from other manufacturers. They are often called “STI“ or “EG“ taps. Compatibility cannot be guaranteed, so it is always recommended to test from case to case.

BAERCOIL Thread Forming Tap
The thread is formed and not cut. Specialized BaerCoil® forming taps, which form and plasticize the material, are used for this purpose. The parent thread material is compressed to make it stronger.
Result: The thread into which the BaerCoil® insert is installed has a significantly higher load capacity.
The process of thread forming is faster and produces a better surface than thread cutting. Additionally there are no chips, and the tap has a longer life time.
