Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M22 x 1.5 The Baer Heli Coil Tap is the precise, high-performance tool you turn to when you need reliable, repair-grade threads for Heli-Coil wire thread inserts. Engineered for durability and designed to deliver clean, repeatable results, this bottoming tap creates full-depth threads that ensure the insert seats perfectly and stays locked in under load. Key advantages that set this tap apart: - Precision HSSG construction for long-lasting wear resistance in tough materials, from aluminum to hardened steels. The ground, heat-treated steel keeps its edge through demanding job sites, reducing the risk of deformed threads. - Bottoming (STI) geometry for complete thread depth. This tap reaches the final thread, allowing Heli-Coil inserts to sit flush and function as if they were original threads — ideal for high-stress environments. - Metric accuracy for M22 x 1.5 threads. The tap is tailored to standard metric specs, making it the go-to choice for repairing or reinforcing holes that require a robust, reliable 22 mm diameter thread with a 1.5 mm pitch. - Consistent results across applications. Whether you’re repairing stripped holes in engine blocks, cylinder heads, or heavy machinery housings, this tap delivers reproducible threads that support durable insert installation and lasting performance. Who benefits most: - Technicians and machinists performing thread repairs or reinforcements in automotive, industrial, and aerospace maintenance. - Shops that rely on quick, repeatable insert installations to extend component life and maintain equipment uptime. - Anyone needing to restore original thread integrity in worn or damaged holes without resorting to oversized taps or costly replacements. Use cases and practical guidance: - Prepare the workpiece with a clean hole and the correct drill size for M22 x 1.5 prior to tapping. - Use appropriate cutting fluid to minimize heat, improve chip evacuation, and extend tool life. - Align the tap carefully with the hole and apply steady, even pressure while turning clockwise to cut a clean, true thread. - After tapping, test with a compatible Heli-Coil insert to verify seating depth and thread engagement before installation. - Store the tap clean and dry to preserve edge geometry and prevent corrosion between jobs. Material advantages translate to real-world outcomes: - Durable HSSG tooling means fewer tool changes, less downtime, and consistent thread quality across multiple repairs. - Full-depth, bottoming geometry reduces the risk of partial threads that can compromise insert performance, giving you stronger, more reliable repairs.
