Baer Heli Coil Tap is the precision tool you need for impeccable thread repairs and reinforcements with wire thread inserts. Designed for metric M20 x 1.5 applications, this bottoming tap (STI) delivers true, full-depth threads that helicoil inserts can bite into with confidence, even in challenging materials and hard-to-reach blind holes.

Why this bottoming tap matters

The bottoming geometry reaches the entire thread length, ensuring clean, square threads from top to bottom. This creates a reliable seat for helicoil inserts, reducing the chances of partial engagement and improving the insert’s pull-out resistance under load. Crafted for durability and consistency, it’s the tool shop owners, machinists, and automotive technicians reach for when reliability isn’t optional.

Key benefits

• Deep, full-depth threads for maximum insert engagement and lasting performance.
• Metric M20 x 1.5 compatibility aligns with common helicoil insert standards for larger, fine-pitched repairs.
• Precise, burr-free thread formation helps inserts seat smoothly and stay secured over time.
• Durable, professional-grade construction built to withstand repeated use in demanding environments.

Ideal use cases

Perfect for repairing damaged or stripped threads in metal housings, engine components, and various machinery where a helicoil insert is the chosen solution for restoring strength and service life. Use this tap to create the ideal foundation for a durable insert, delivering reliable engagement and long-term torque resistance.

Practical guidance

• Prepare the hole to the correct pilot size for M20 x 1.5 helicoil inserts.
• Apply appropriate cutting lubricant and maintain steady, even pressure to achieve clean threads.
• Clean chips regularly to prevent binding and ensure a smooth tapping action.
• Install the helicoil insert per manufacturer instructions to maximize performance.
