Baer Heli Coil Tap – M16 x 2, Spiral Flute Tap (STI) designed to work in perfect harmony with Heli-Coil wire thread inserts. This precision tap cuts clean, true host threads that are ready to accept a durable coil insert, delivering trustworthy repairs and reinforced joints in metal components.

Engineered for reliability and long service life, this tap is crafted from premium high-speed steel (HSS) and finished to stand up to the demands of repeated use. The spiral-flute design enhances chip evacuation and reduces binding, making it ideal for through-holes and challenging materials alike. When paired with Heli-Coil inserts, it creates a hardened, wear-resistant thread that resists pulling and stripping under load.

What makes this tap essential

• Direct compatibility with Heli-Coil inserts – precisely cuts the matching host thread to ensure optimal insert engagement and strength.
• Spiral flute for efficient cutting – self-cleans as you drill, promoting deeper taps with less resistance and smoother operation.
• Metric M16 x 2 sizing – ideal for reinforcement and repairs in structural fastener areas where a robust, standardized thread matters.
• Durable construction – built from high-grade HSS with a finish designed to withstand frequent use in automotive, machinery, and manufacturing settings.

Practical use cases

• Repairing stripped or damaged threads in engine blocks, transmission housings, crankcases, and aluminum components where an insert is preferred for longevity.
• Creating reliable, serviceable threads in equipment housings and brackets that endure vibration and repeated assembly/disassembly.
• Reinforcing critical fastener locations in rebuilds or retrofits where replacing the entire component isn’t feasible.

How to get the best results

1. Choose the correct drill size for your Heli-Coil insert kit to match the M16 x 2 thread.
2. Use cutting fluid or light oil to reduce heat and extend tool life during tapping.
3. Align the tap carefully with the hole axis and apply steady, even pressure while turning clockwise.
4. After tapping, install the Heli-Coil insert according to the kit instructions to achieve a reinforced, durable thread ready for repeated use.

Care and storage: Keep the tap clean of chips, wipe with a dry cloth after use, and store in a protective case to prevent nicks and corrosion. Proper maintenance ensures the tool stays precise and dependable for future repairs.
