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).
The tapping operation for STI holes is basically
the same as for the tapping of standard holes.
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 Bottoming Tap
The most popular and versatile type is the BAERCOIL bottoming tap. These can be used by hand or machine and for through or blind holes.

BAERCOIL Machine Tap
Machine Taps are used for higher production volumes.
Form B Tap
The Form B Tap is used for through holes.
Recommended for machine tapping through holes or blind holes providing that there is ample clearance beyond the threaded section to accommodate the chips
■ Modern design, shape and geometry incorporating short pod length
■ These taps provide for chip clearance by pushing the chips ahead of the tap
■ Spiral Point taps have straight flutes supplemented by angular cutting faces at the point
■ The shearing action of the angular cutting faces produce a fine finish on the threads
■ Shallower flutes achieve a stronger cross section which allows the tap to withstand high cutting force
■ Maybe successful for hand tapping on difficult to tap materials
■ High performance tap made from HSSE

Form C Tap
The Form C Tap with Spiral Flutes is used for blind Holes.
Recommended for machine tapping for all blind hole applications, particularly in soft materials such as copper, magnesium and aluminium which produce long stringy swarf.
Modern design, shape and geometry incorporating short pod length.
The shear action provided by the spiral flutes draws the swarf out of the hole allowing a greater depth of threading without the swarf clogging.

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.

BAERCOIL Pilot Nose Tap
Pilot nose taps have been developed for repairing damaged threads without the need for drilling prior to tapping.
This style of tap allows the use of the existing thread as a
guide in tapping a straight hole. These taps remove the requirement of drilling prior to tapping for the purpose of thread repair. Very suitable for repairing of spark plug threads.
