Baer Heli Coil Tap - Wire Thread Insert - Spiral Flute Tap (STI) - Metric - M6 x 1

The Baer Heli Coil Tap - Wire Thread Insert - Spiral Flute Tap (STI) - Metric - M6 x 1 is a precision tapping solution designed to create flawless internal threads ready for Heli-Coil style wire thread inserts. Engineered for durability and consistent performance, this spiral flute tap delivers clean, true threads that lock inserts in place and resist pull-out under load.

Why this tap stands out

• Sharp, durable construction: manufactured for repeated use in tough metals, with a robust flute geometry that maintains accuracy from first cut to the final pass.
• Spiral flute design: optimized for rapid chip evacuation and smoother cutting, reducing friction and the risk of cross-threading in hard-to-reach holes.
• Metric precision for M6 x 1 applications, ensuring compatible threads that accept standard Heli-Coil inserts with reliable engagement.
• STI compatibility: engineered for spiral-flute tapping workflows that professionals rely on for consistent results across diverse projects.
• Quality you can trust: built to maintain dimensional accuracy, delivering repeatable performance across automotive, industrial, and DIY repair tasks.

Ideal use cases

• Repairing stripped or damaged threads in aluminum, steel, and cast materials where insert-backed strength is essential.
• Reinforcing critical mounting holes on engine components, transmission cases, machinery frames, and automotive housings that endure high vibration and load.
• Repairs in soft metals where traditional taps risk chatter or chip buildup, ensuring clean, durable threads every time.
• Prep for wire thread inserts in applications requiring quick field repairs or permanent reinforcements that restore original thread strength.

How to get the best results

1. Prepare the hole: clean, deburr, and verify perpendicularity to ensure the tap cuts true threads.
2. Lubricate the tap to reduce friction and extend tool life during the cut.
3. Align the tap straight to the hole, apply steady, even pressure, and rotate clockwise with consistent hand or machine torque.
4. Back out periodically to break and clear chips—this helps maintain thread geometry and prevents binding.
5. Once tapping is complete, clean the hole thoroughly before installing the wire thread insert with the appropriate installation tool.
