• Durable cutting construction: Built for longevity, with a robust tooling grade (HSSG) that maintains sharpness and accuracy under demanding tapping tasks.
• Optimized for wire thread inserts: Creates the exact female threads that Heli-Coil inserts require to restore damaged threads or reinforce soft materials.
• Versatile, professional-grade performance: Suitable for automotive, machinery maintenance, and equipment repair where dependable thread repair is non-negotiable.

Practical use cases

• Repair stripped M22 x 2.5 threads in engine blocks, cylinder heads, and transmission housings.
• Reinforce threaded holes in aluminum, cast iron, and mild steel components to extend service life.
• Restore mounting points for sensors, brackets, and housings that experience repeated fastening cycles.

Tips for best results

1. Lock the tap squarely in the hole to maintain coaxial alignment and prevent cross-threading.
2. Use appropriate cutting fluid or tapping oil to reduce friction and heat buildup, especially in tougher alloys.
3. Tap at a steady pace with light, consistent pressure; back off slightly to clear chips and then resume to full depth.
4. Always pair the final hole with a matching Heli-Coil insert for optimal strength and vibration resistance.

The Baer Heli Coil Tap is more than a tool — it’s a reliability upgrade for your repair kit. When threaded holes must withstand routine service and heavy loads, choose a tap that delivers precision, durability, and confidence in every cut. Add it to your toolkit and restore thread integrity with professional-grade efficiency.
