Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M20 x 2

The Baer Heli Coil Tap is your dedicated solution for impeccable thread repairs and reinforcements with metric precision. Designed as a bottoming tap for M20 x 2, it delivers clean, accurate threads that are perfectly suited for installing Heli-Coil wire thread inserts and repairing damaged holes in a wide range of metal applications.

Why this bottoming tap stands out

• Bottoming engagement for complete depth: The tap geometry reaches the full thread depth, making it ideal for blind holes and ensuring every insert seats squarely.
• Metric accuracy you can trust: Specifically engineered for M20 x 2 threads, so you’ll get consistent pitch, fit, and strength with every use.
• Durable, shop-ready construction: Built to withstand repetitive tapping in busy workshop environments, delivering reliable performance project after project.
• Optimized for Heli-Coil inserts: Precisely cut threads create a secure, vibration-resistant anchor for wire thread inserts, restoring original clamping force and load-bearing capacity.
• Versatile repair or reinforcements: Ideal for restoring stripped or damaged threads in automotive components, machinery housings, brackets, and other metal assemblies.

Practical use cases

• Repairing stripped threads in engine blocks, cylinder heads, or intake manifolds where a strong, durable repair is essential.
• Reinforcing mounting holes in aluminum or steel brackets that experience frequent disassembly and reassembly.
• Preparing blind holes for secure fastener installation in fabrication, automotive, or industrial equipment projects.

How to use with confidence

1. Align the hole and choose the correct drill size for your M20 x 2 tap guidance.
2. Lubricate the thread-formation area to reduce friction and improve finish quality.
3. Carefully advance the tap with steady, even pressure, using a T-handle or tapping machine until the full thread depth is engaged.
4. Clean the hole and inspect the newly cut threads, then install the Heli-Coil insert for a robust, reusable thread.

Who benefits most

• Professional machinists and technicians who need repeatable, repair-ready threads tied to standard insert systems.
• DIY enthusiasts tackling critical thread repairs on vehicles, equipment, and home projects where reliability matters.

With the Baer Heli Coil Tap, you’re not just cutting threads—you’re restoring integrity and extending the life of essential components. Invest in a tool that makes precision, durability, and compatibility with Heli-Coil wire thread inserts a predictable part of every repair workflow.
