Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - UNC - No. 10 x 24

The Baer Heli Coil Tap is the precision tool you reach for when thread integrity matters. Designed specifically for creating strong, repair-ready threads with wire thread inserts, this bottoming tap (STI) is sized for UNC No. 10 x 24 applications, delivering reliable engagement every time.

• Bottoming clarity for blind holes: Full-depth threading to the very bottom of the hole ensures the Heli-Coil insert seats perfectly, delivering consistent load-bearing capacity and long-term durability.
• UNC No. 10 x 24 compatibility: Precisely matched to standard fasteners used in automotive, machinery, and equipment, reducing guesswork during repairs or reinforcements.
• Dedicated for wire thread inserts: Engineered to pair with Heli-Coil inserts, providing clean, metal-to-metal engagement that resists pull-out and thread wear under service loads.
• Durable, repeatable performance: The tap’s robust geometry minimizes chip buildup, improves alignment, and extends tool life through demanding workshops and field jobs.
• Versatile repair solution: Ideal for restoring stripped or damaged threads in aluminum, steel, and other common substrates, turning tired holes into reliable fastener anchors.

Use cases and scenarios

Automotive repair: restore damaged cylinder head or engine block threads without resorting to oversized heli-coils or costly replacements. Industrial equipment: reinforce critical mounting holes that routinely endure vibration and dynamic loads. Hobbyist projects: salvage worn threads in metal enclosures, brackets, and fixtures with professional-grade results.

Why this tap matters

In any scenario where a secure, reusable thread matters, the Heli Coil Tap enables you to prepare precise threads that accept high-strength inserts. Compared to generic taps, this bottoming design delivers complete thread depth and consistent performance, reducing the risk of insert failure and ensuring repairs stand up to real-world use.

To get the best results, pair this tap with the corresponding Heli-Coil inserts and use standard cutting fluid to minimize friction and heat. Maintain clean, deburred holes and follow rated depth guidelines to maximize insert longevity and thread strength.
