The Baer Heli Coil Tap is the precise, reliable tool you need for impeccable thread repairs and reinforcement with Heli-Coil wire inserts. Designed for UNF 3/4 x 16 applications, this bottoming tap delivers clean, true threads all the way to the bottom of the hole, ensuring the insert seats correctly and performs under load from day one.

  • Bottoming design for full-depth threads: cut to the final depth so the Heli-Coil insert nests securely and provides maximum pull-out resistance in high-stress assemblies.
  • UNF 3/4 x 16 compatibility: optimized for finer-thread holes found in critical components where strength and precision matter.
  • STI-ready threading: creates the exact internal geometry required for reliable wire-thread inserts that restore damaged threads or reinforce high-load connections.
  • Durable, consistent performance: engineered to maintain accuracy across multiple jobs, producing repeatable results you can trust on every project.
  • Versatile application: ideal for automotive engine bays, machinery housings, and other metal parts where threaded reinforcements extend service life and reduce downtime.

Usage overview: Prepare the hole to the insert’s specification, align the Baer Heli Coil Tap and cut to full depth with controlled feed, then clean the hole and install the Heli-Coil insert for secure, long-lasting threads. This tap is purpose-built to deliver dependable results when you need to repair or reinforce threads that will see vibration, loads, and repeated assembly cycles.
