Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M10 x 1.5

The Baer Heli Coil Tap is a precision STI bottoming tap engineered for flawless thread repairs and reliable reinforcement with BaerCoil wire thread inserts. Built to exact standards, this tap supports durable, insert-ready threads in metric holes, delivering repeatable results in a variety of materials.

What makes this tap stand out is its specialized geometry and alignment features, purpose-built to work with standard Helicoil-style inserts. These design elements help you achieve accurate thread formation on the first pass, minimize runout, and ensure the insert seats correctly for long-lasting repairs.

• Bottoming geometry for full-depth engagement. Creates threads right to the bottom of the hole, enabling clean, insert-ready threads every time. This is essential for blind holes and high-load applications.
• Insert-friendly geometry. The tap is designed to hold and align the wire thread insert during tapping, reducing walk-off and misalignment that can compromise warranty-worthy repairs.
• Metric size M10 x 1.5. Specifically matched to the most common insert size, ensuring compatibility with BaerCoil and other Helicoil-style inserts.
• Durable construction for shop-to-field reliability. Built to withstand repeated use in metals and engineered plastics, providing consistent performance across jobs.
• Designed for insert installations. When paired with the corresponding BaerCoil thread inserts, this STI tap forms threads that securely anchor the insert, delivering reinforced strength where original threads have worn or failed.

This tap is ideal for: repairing stripped threads in critical assemblies, reinforcing soft or fatigued holes, and restoring service life in automotive, aerospace-adjacent, machinery, and general fabrication environments. It’s particularly valuable when you need a trusted process to install wire thread inserts cleanly and predictably, without compromising surrounding material or hole geometry.

How to get the best results: use the drill size recommended by your insert kit for M10 x 1.5, apply a compatible cutting fluid, and tap to the insert’s recommended depth. After tapping, install the wire thread insert per the insert vendor’s instructions to achieve maximum pull-out resistance and load-bearing capacity.

In short, the Baer Heli Coil Tap delivers precise, insert-compatible threads with bottoming accuracy, helping you restore damaged threads and extend the life of critical holes with confidence.
