Baer Heli Coil Tap – Wire Thread Insert – Bottoming Tap (STI) – Metric – M30 x 2 is your go-to precision tool for clean, reliable thread repairs and reinforcements. Built to endure demanding machining work, this tap delivers consistent pitch control and accurate depth when installing Heli-Coil wire thread inserts in metric M30 x 2 holes.

Why this Baer Heli Coil Tap stands out

  • Durable HSSG construction combines toughness and wear resistance to handle tough materials and repeated use without dulling or wandering off-axis.
  • Bottoming (STI) design reaches the final thread depth, ensuring full engagement in blind holes so inserts seat securely from top to bottom.
  • Metric M30 x 2 specification provides precise, standardized threading suitable for repair, reinforcement, and restoration tasks where a robust, high-strength internal thread is critical.
  • Optimized for insert seating geometry creates clean threads that match Heli-Coil inserts, promoting smooth installation and long service life of the repaired joint.
  • Tough, reliable performance built for automotive, manufacturing, and equipment maintenance environments where dependable thread repair is non-negotiable.

This tap is designed for professionals and serious hobbyists who need durable, repeatable results when restoring stripped threads or reinforcing critical joints. With the Baer Heli Coil Tap, you can confidently repair mounting holes, brackets, housings, and other components that demand a proven, press-fit thread solution.

Practical use cases and tips

  • Use with compatible Heli-Coil wire thread inserts to restore strength in damaged M30 x 2 threads, restoring clamping force and load-bearing capability.
  • Prepare the hole with the correct pilot drill size, then chase the threads before using the bottoming tap to the full depth for a clean seat.
  • Apply a light cutting fluid and maintain steady, straight alignment to minimize chatter and maximize thread form quality.
  • Inspect the repaired hole after tapping and every few insert cycles to ensure consistent engagement and prevent loosening under load.

Whether you’re restoring critical engine, transmission, or structural components, the Baer Heli Coil Tap (M30 x 2) delivers the reliability you need. It’s the right choice when the goal is durable, serviceable threads that stand up to vibration, torque, and daily wear—backed by a design that prioritizes precision, stability, and long-term performance.
