Recover damaged threads with confidence using the Baer Heli Coil Tap — a dedicated tool for wire thread inserts that’s precision‑toured for metric M20 x 2.5 threads. Designed to support reliable repairs and reinforcements, this Bottoming Tap (STI) delivers consistent performance when working with Helicoil‑style inserts across a range of metal applications.

Why this bottoming tap stands out

• Bottoming action for full-depth threads. The bottoming design provides a continuous cutting edge with minimal taper, enabling you to chase threads right to the bottom of a blind hole for a clean, true seating of the insert. This is essential for high‑load fasteners and repeatable assembly cycles.
• Metric accuracy for M20 x 2.5 threads. Tailored to standard M20 x 2.5 inserts, ensuring the resulting hole dimension matches insert and fastener specifications for a secure repair.
• STI tap design for Helicoil‑style inserts. STI taps are purpose‑built to create threads that perfectly accept standard wire inserts, returning the hole to its intended size and enabling reliable torque and pull‑out performance.
• Repair and reinforcement in demanding components. Use it to restore threads in precision housings, blocks, and assemblies where wear or damage would otherwise compromise service life and reliability. The tap’s geometry supports repeatable results across repair cycles.
• Durable, shop‑tested performance. Built to maintain thread geometry through multiple uses, helping you complete repairs quickly with consistent results.

Practical usage tips: prepare the hole with proper deburr and cleaning, choose the correct insert kit for M20 x 2.5, and follow a steady, controlled tapping motion to preserve alignment. When paired with the corresponding insert tooling, this Baer Heli Coil Tap accelerates repairs and extends the life of critical components.
