Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M7 x 1

Meet the Baer Heli Coil Tap—the precision tool you reach for when threads need to be repaired, reinforced, and trusted to hold. This metric M7 x 1 bottoming tap is engineered to work with Heli-Coil wire thread inserts, delivering clean, durable internal threads that data-safe fasteners can bite into with confidence.

Why this tap stands out:

• Bottoming geometry for true depth. The bottoming design reaches the full depth of blind holes, ensuring the insert seats perfectly and screws engage fully from the first turn.
• Metric precision: M7 x 1. Tailored for common metric assemblies, this tap creates threads that match standard fasteners and Heli-Coil inserts for reliable, repeatable results.
• Rugged, long-lasting construction. Machined from high-speed steel with a durable finish (HSS-G style), it stays sharp longer and resists wear in demanding shop environments.
• Optimized for coil inserts. Pairing with Heli-Coil wire thread inserts, this tap delivers reinforced threads that resist stripping, extending service life in softer metals and high-use components.
• Versatile in function and material compatibility. Ideal for repairing stripped threads in aluminum, steel, and cast alloys, as well as creating robust, insert-ready holes in new assemblies.
• Professional-grade reliability. Built for machinists, repair technicians, and serious DIY enthusiasts who demand consistent accuracy and durable results, time after time.

Practical use notes: maintain proper alignment, apply appropriate cutting oil, and tap with steady, even pressure to avoid breakage. After tapping, clean the hole, install the Heli-Coil insert, and you’ll have a threaded hole that behaves like new—strong, repair-ready, and ready to perform.
