Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M10 x 1.25

The Baer Heli Coil Tap is the reliable, precision tool you need for flawless thread repairs and reinforced is optional, reinforcements. Engineered for durability and consistent performance, this metric bottoming tap (M10 x 1.25) is designed to work seamlessly with Heli-Coil wire thread inserts, delivering clean, square-cut threads that seat inserts securely every time.

Key features that matter in real-world work

• Metric precision, built to last: M10 x 1.25 threads cut with tight tolerances, ensuring repeatable results across metal, aluminum, and steel components.
• Bottoming tap design: Full-depth threading to the bottom of the hole, enabling proper seating of coil inserts and maximum engagement for load-bearing repairs.
• Durable HSS-G core: High-speed steel construction with a robust ground finish for extended use in workshop settings and on tough materials.
• Clean, accurate threads: Flank geometry and cutting edges engineered to minimize chatter and reduce the risk of cross-threading during installation.
• Versatile compatibility: Ideal partner for standard Heli-Coil repair kits and metric insert systems, simplifying repairs in automotive, machinery, and maintenance applications.

Why choose this tap for your repairs

When threads are stripped or worn, a coil insert restores strength, torque tolerance, and service life without a full component replacement. The Baer Heli Coil Tap guarantees the precise thread form your insert needs, enabling you to:

• Repair damaged threaded holes in engine blocks, housings, brackets, and fastener points with confidence.
• Restore critical alignment and load paths in machinery where consistent torque and pull-out resistance are essential.
• Prepare clean, true threads that prevent insert seating issues and ensure long-term reliability.

Practical use cases

• Automotive maintenance: repairing stripped mounting holes in cylinder heads, engine blocks, or transmission housings.
• Industrial equipment: reinstating threaded cavities in pumps, gearboxes, and hydraulic manifolds.
• Machining and fabrication: restoring tapped holes in steel fixtures, aluminum brackets, and weldments.
• DIY and precision projects: anytime you need durable, repairable threads that last longer than standard taps alone.

How to maximize results

• Follow the insert kit’s guidance for the correct drill size to match M10 x 1.25 inserts, then use the Baer Heli Coil Tap to cut the full-depth threads.
• Lubricate during tapping to reduce friction and extend tool life.
• Clean the hole after tapping to remove chips before installing the coil insert.
• Install the wire thread insert with the proper driver tool for secure, vibration-resistant performance.

With the Baer Heli Coil Tap in your toolkit, you gain a reliable, repeatable solution for repairing and reinforcing threaded holes. Precision-made, durable, and purpose-built for Heli-Coil inserts, this tap helps you finish jobs stronger and faster—so you can get back to work with confidence.
