Description
Baer Heli Coil Tap – the dedicated wire thread insert preparation tool designed for impeccable thread repairs and reinforcements. Built to endure tough jobs, this Spiral Point Tap (STI) is engineered to cut precise, reliable threads for M14 x 1.5 holes, creating the perfect foundation for standard helicoil inserts and long-lasting repairs.

Why the Baer Heli Coil Tap stands out

- Consistent thread depth and alignment — designed to produce uniform threads that align perfectly with the helicoil insert, minimizing rework and ensuring consistent torque performance.
- Versatile across common maintenance tasks — ideal for repairing damaged threads in a variety of metals and components when paired with the appropriate drill size and helicoil system.
Ideal applications
Use the Baer Heli Coil Tap for repairing stripped or worn threads where a helicoil insert is required.
