Introducing the Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M2.5 x 0.45. This precision tool is engineered to pair with Heli-Coil wire thread inserts, delivering clean, repeatable thread cuts for reliable repairs and reinforced fastener assemblies in metal and engineered plastics.

Why this tap stands out

  • Bottoming geometry ensures full-depth thread formation, allowing the Heli-Coil insert to seat flush and perform under load.
  • Made from high-speed steel (HSS-G) with precise grinding to hold tight tolerances for repeated use.
  • Metric size M2.5 x 0.45—fits standard M2.5 repair kits and accepts common M2.5 fasteners with confidence.
  • Designed specifically for use with wire thread inserts to repair stripped or damaged threads in metal components, improving torque resistance and longevity.
  • Long tool life due to hardened cutting edges and robust shank geometry, reducing downtime on the bench or in the workshop.

Who benefits most

Perfect for technicians, machinists, and hobbyists working on automotive panels, CNC-machined parts, electronics housings, or any assembly where a compact, high-strength thread is essential. When you need to restore threaded strength in blind holes, this bottoming tap ensures the insert seats precisely and the finished thread remains true over time.

How to use

  1. Confirm the correct drill size and Heli-Coil insert kit for M2.5 x 0.45 and prepare the hole accordingly.
  2. Using the Baer Heli Coil Tap, cut threads with a steady, controlled motion to the full depth to allow the insert to sit flush with the surface.
  3. Deburr and clean the hole to remove chips that could affect insert seating.
  4. Install the Heli-Coil insert with the appropriate installation tool until it sits flush or slightly below the surface, as required by your application.
  5. Test the repaired thread with a compatible screw to verify fit and seating, ensuring reliable torque and pull-out resistance.

Choose the Baer Heli Coil Tap to deliver reliable, durable thread repairs that resist wear and keep assemblies running smoothly. Built for precision, longevity, and consistent results, it’s the trusted choice for professional thread reinforcement with metric M2.5 x 0.45 threading.
