Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M18 x 2.5 is a precision tapping tool designed for creating robust, long-lasting threads that accept Heli-Coil wire thread inserts with confidence. This bottoming tap is engineered to deliver full-depth threads in through-holes and blind-holes, ensuring your inserts seat cleanly and perform under demanding use.

  • High-Performance HSS-G construction: Ground, heat-treated high-speed steel for consistent thread formation and extended tool life in tough metals.
  • Metric M18 x 2.5 thread specification: Precisely sized for standard Baer Heli-Coil inserts and compatible components, delivering reliable engagement and torque transfer.
  • Bottoming tap design: Reaches the final thread depth, enabling complete engagement of the insert and minimizing the risk of pull-out in high-stress applications.
  • Optimized for the Heli-Coil system: Specifically paired with wire thread inserts to restore damaged threads or reinforce critical mounting points in automotive, machinery, and industrial equipment.
  • Versatile repair and reinforcement tool: Ideal for repairing stripped threads in aluminum, steel, and other common metals; supports enduring performance in repeated loading scenarios.
  • Use-case clarity: For repairs where a blind hole needs threads to run to the bottom or for creating new, durable threads in serviceable components that require frequent disassembly.

Whether you're a professional technician, machinist, or serious DIYer, this Baer Heli Coil Tap delivers predictable results, reduces downtime, and extends the life of critical assemblies. Pro-tip: keep cutting fluid or light oil on hand to reduce galling and extend tap life, and ensure the tap axis stays perfectly aligned with the hole axis to achieve clean, accurate threads.
