The Baer Heli Coil Tap is a purpose-built tool designed to cut precise internal threads that accept wire thread inserts. Specifically engineered for spiral coil (STI) installations, this tap creates the robust receiving threads you need when repairing stripped or damaged holes. With its metric form, this tap locks into place for consistent engagement, delivering reliable results in a range of materials and applications.

• Precisely oversized for insert compatibility. The tap is designed to generate threads that match the outer profile of standard wire thread inserts, ensuring a snug, secure seating every time.
• Spiral Point (gun nose) geometry. The cutting edges are positioned to push chips forward and keep debris out of the hole, making through-hole tapping smoother and reducing the risk of cross-threading.
• Metric reliability: M14 x 1.25 pitch. This specific size and pitch are common for automotive, machinery, and maintenance work, providing a dependable port for helicoil-type inserts.
• Single-tool solution for repair and reinforcement. Use this tap to restore damaged threads or create a durable core for a helicoil or similar wire insert, extending service life and load-bearing capacity.
• Versatile for tough environments. Ideal for repair in metal housings, engine components, transmission casings, and other critical assemblies where strong, repeatable threads matter.

Why choose this Baer Coil Tap? It’s built to support real-world repairs where standard taps fall short. The STI-oriented design focuses on producing clean, accurately sized threads that align perfectly with the insert you’re seating, minimizing rework and downtime. For technicians, machinists, and hobbyists who demand repeatable outcomes, this tap offers dependable performance that translates to fewer failures and longer-lasting fixes.

Practical use cases:

• Repairing stripped M14 x 1.25 threaded holes in engine blocks, cylinder heads, or transmission housings.
• Preparing through-holes in aluminum or steel brackets that will receive helicoil-type wire inserts for heightened durability.
• Restoring critical threads in chassis components where vibration resistance and restoring torque are essential.

Tips for best results:

• Follow the insert manufacturer’s guidance for hole size and drill depth to ensure proper seating of the wire insert.
• Use appropriate cutting oil or spray to reduce friction and extend tap life during tapping.
• Keep the tap aligned with the hole to avoid cross-threading and errant cuts, especially in deeper or harder materials.
• Deburr the hole after drilling and before tapping to prevent chip interference and ensure clean thread engagement.
