Designed for bottoming operations, this tap brings the full thread depth to blind holes, ensuring flawless engagement with Heli-Coil inserts and reinforced fasteners across a variety of metals.

• Rugged, real-world durability — built from high-quality HSS-G to resist wear in steel, aluminum, and other common base materials, so you can rely on consistent performance project after project.
• Optimized for wire thread inserts — its geometry is tuned for smooth cutting and precise thread formation when paired with Heli-Coil inserts, reducing chatter and producing defect-free threads.
• Bottoming tap (STI) design — enables full-depth threading in blind holes, eliminating undercutting and ensuring the insert seats securely from top to bottom for maximum pull-out resistance.
• BA - 6 x specification — clearly labeled for compatibility with standard insert kits and applications that rely on exact sizing for reliable repairs and reinforcements.
• Versatile repair tool — ideal for repairing stripped threads in automotive components, machinery housings, brackets, and other critical parts where strong, repeatable threads are essential.

Why this tap matters — when you’re restoring threaded connections that see high load or frequent disassembly, a bottoming Heli-Coil tap ensures the new threads anchor the insert securely, preserving structural integrity and extending the life of the component. It’s the difference between a temporary fix and a durable repair you can trust for years of service.

Practical tips for best results

• Pair with the matching drill size and insert kit to achieve optimal thread geometry for BA - 6 x entries.
• Use light, steady cutting fluid or lubricant to reduce heat and prolong tool life during tapping.
• Clean and deburr the hole before tapping to prevent binding and ensure smooth insert seating.
• After tapping, inspect the threads and test the insert fit to confirm full-depth engagement and even seating.
