Baer Heli Coil Tap is the premium tapping solution you reach for when thread integrity matters. This M12 x 1 metric bottoming tap is purpose-built to create clean, installation-ready threads that pair perfectly with Heli-Coil wire inserts, delivering durable, repair-grade strength in a wide range of applications.

• Premium HSS-G construction delivers long wear life and dependable performance in steel, aluminum, and other common metals. The tool is engineered to resist galling and maintain precise thread profiles through repeated use.
• Bottoming (STI) geometry taps every last thread to the bottom of blind holes, ensuring full engagement of the coil insert and maximum load-bearing capacity where it’s needed most.
• Metric accuracy ensures compatibility with standard M12 x 1 Heli-Coil inserts, making it a trusted choice for automotive, machinery, and industrial repair work.
• Precision-ground finish provides consistent thread pitch and pitch diameter, resulting in smoother tapping, fewer misthreads, and reliable coil installation every time.
• Designed for repair, not replacement — ideal for restoring stripped or damaged threads in critical components, from engine blocks to control housings, without compromising surrounding material.

Who benefits from the Baer Heli Coil Tap? technicians, machinists, and shop floor specialists who routinely repair damaged threads and restore service life to components. It’s particularly valuable when Heli-Coil wire inserts are the chosen solution for reinforcing soft or high-load threads, providing renewed strength and resistance to future wear.

Common scenarios include rebuilding stripped M12 x 1 holes in automotive engines, airflow components, hydraulic manifolds, and precision machinery housings. In these contexts, the bottoming tap guarantees a complete thread depth, enabling the insert to seat securely and perform under real-world stresses.

Practical tips for best results (without overcomplicating the process): use appropriate cutting fluid, maintain a steady, perpendicular tapping motion, and keep chips cleared to prevent binding. After tapping, prepare the hole for the insert, then install the Heli-Coil with the accompanying tooling to achieve a clean, reinforced thread path.

Choose the Baer Heli Coil Tap for a dependable, engineer-approved solution that enhances repair quality, extends component life, and keeps your equipment running smoothly. It’s the right tool for professionals who demand consistency, durability, and precision in every threaded repair.
