Baer Heli Coil Tap is your go-to tool for impeccable thread repairs and robust thread reinforcements with wire thread inserts. Specially sized for BSP standards, this bottoming tap (STI) delivers precise 3/4 x 14 threads, creating a clean foundation for Heli-Coil style inserts and ensuring long-lasting, vibration-resistant joints in a variety of metals.

Designed for durability and precision, the Baer Heli Coil Tap features a bottoming geometry that reaches the full thread depth, even in blind holes. This means you won’t miss engagement at the deepest point, and you’ll achieve a consistent, repeatable thread every time. The result is reliable insert performance, reduced risk of cross-threading, and fewer re-taps in demanding maintenance scenarios. Key benefits you’ll notice in practice: - Exact BSP 3/4 x 14 thread form, matching standard Heli-Coil style inserts for quick, confident repairs. - Bottoming tap design ensures complete thread depth, so repairs hold up under load and torque. - Built to withstand repeated use across common substrates like steel, cast iron, and aluminum, making it a versatile addition to any shop or workshop. - Improves longevity of critical connections by providing true, repair-grade threads that resist stripping and pull-out. - Supports professional-grade thread reinforcement without resorting to epoxy or oversized holes. Usage in real-world tasks: - Repairing stripped or damaged BSP threads on machinery housings, hydraulic components, and plumbing fittings. - Restoring worn holes in automation equipment where a secure, insert-backed thread is essential for reliability. - Preparing holes for wire thread inserts in maintenance projects that demand durable, high-cycle performance. How this tap fits into your workflow: - Pair with the appropriate drill size for BSP 3/4 x 14, keep cutting fluid on hand, and maintain steady, perpendicular alignment during tapping. - Clean chips frequently and back off periodically to avoid binding; this preserves thread geometry and tool life. - After tapping, install the corresponding wire thread insert to achieve reinforced, load-bearing threads that resist fatigue. Ideal for professional machinists, automotive technicians, plumbers, and serious DIY enthusiasts who demand precision, durability, and repeatable results. With the Baer Heli Coil Tap in your toolkit, you can confidently repair damaged threads, extend the life of critical components, and maintain optimal performance across a wide range of applications. Invest in precision. Restore integrity. Choose Baer Heli Coil Tap for dependable BSP 3/4 x 14 thread repairs that stand the test of time.
