Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - BSF - 11/16 x 14

The Baer Heli Coil Tap is the precise, professional-grade tool you rely on for flawless internal threading when installing wire thread inserts. Specifically designed for BSF threads and cutting 11/16 x 14, this bottoming tap ensures you reach full thread depth every time, even in blind holes, so your Helicoil inserts seat securely and perform under load.

• Robust construction: Crafted from high-quality steel with precision-ground flutes for clean, accurate thread formation and long-lasting durability in demanding projects.
• Bottoming design for full-depth threads: The bottoming geometry guarantees engagement to the bottom of the hole, delivering reliable insert retention and maximum pull-out resistance.
• BSF, 11/16 x 14 specification: Tailored for classic British Standard Fine threads, making it an ideal choice for repairing or reinforcing critical mounting points in automotive, industrial, and machinery applications.
• Optimized for Heli-Coil inserts: Pair this tap with Helicoil wire thread inserts to restore damaged threads or add durable reinforcement where threads are under heavy use or frequent disassembly.
• Machinist-friendly design: Shank compatibility with standard tapping handles and guides keeps your work aligned and consistent, reducing chatter and mis-taps.

Use cases span a wide range of projects—from restoring stripped threads in engines and transmissions to reinforcing threaded holes in aluminum housings and steel brackets. Whether you’re a professional machinist, a repair technician, or a serious hobbyist, this tap helps you extend component life, improve repair reliability, and reduce the cost of ongoing maintenance by restoring threads to their original strength.

What sets the Baer Heli Coil Tap apart is its combination of precision, durability, and kit compatibility. With a tool that cuts true BSF threads at 11/16 x 14 and a design optimized for clean engagement with Helicoil inserts, you’ll experience fewer reworks, quicker repairs, and more consistent results across projects.

Tips for best results: choose a quality cutting fluid, maintain a steady, perpendicular approach to the workpiece, and use a proper tapping guide to prevent wandering. After tapping, deburr the hole, clean any chips, and install the Helicoil insert according to the manufacturer’s instructions for a durable, vibration-resistant thread repair.
