Baer Heli Coil Tap – Wire Thread Insert – Bottoming Tap (STI) – UNF – 1 x 14

Designed for precise, reliable thread repairs and reinforcements, this Heli Coil Tap is a trusted companion for machinists, technicians, and serious DIYers. Built to withstand demanding work in steel, aluminum, and castings, it delivers clean, accurate internal threads that pair perfectly with Heli-Coil wire thread inserts for long-lasting hole reliability.

• Bottoming tap geometry ensures full-depth threads in blind holes, delivering consistent engagement for insert installation and load-bearing performance.
• UNF 1 x 14 thread compatibility provides a fine-thread standard that matches common insert systems, helping you restore or reinforce critical holes with confidence.
• Durable construction built from high-quality tool steel (engineered for durability) to stand up to repeated use in a busy shop environment.
• Precise, controlled cutting designed to minimize chatter and reduce thread distortion, so repairs hold up under vibration, torque, and dynamic loads.
• Versatile application ideal for automotive, aerospace, machinery maintenance, and general repairs where damaged threads threaten performance or safety.

How it works

1. Prepare the hole by cleaning and deburring to ensure smooth cutting.
2. Align the Baer Heli Coil Tap with the hole and apply light, consistent cutting oil to reduce friction.
3. Turn the tap steadily to cut clean, bottomed threads to the full depth, creating the ideal seat for the Heli-Coil insert.
4. Follow with the matching Heli-Coil wire thread insert to restore original strength and distribute loads evenly.
