Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - BS. Brass - 3/8 x 26

Baer Heli Coil Tap — Wire Thread Insert — Bottoming Tap (STI) in 3/8 x 26, crafted to deliver precise, durable thread repairs and reinforcements. Built to handle the demands of professional repair work, this tap ensures clean, true-cut threads that form a solid foundation for Heli-Coil inserts.

Designed for reliability in blind holes, the bottoming geometry reaches to the final depth, producing consistent thread engagement every time. When paired with Heli-Coil wire thread inserts, it creates reinforced threads that resist vibration, prevent pull-out, and extend the life of critical components in automotive, machinery, and everyday equipment repairs.

• Bottoming precision: cuts threads to the full depth of blind holes for dependable insert engagement and long-lasting repairs.
• 3/8 x 26 size: matched to common Heli-Coil insert applications, enabling straightforward substitution and repair workflows.
• Durable construction: crafted from high‑quality tooling steel with a robust finish to withstand repeated use in tough materials.
• Square-drive shank: designed for secure, accurate wrench engagement, reducing chatter and improving control during tapping.
• Optimized for wire thread inserts: specifically aligned to create the ideal threads for Heli-Coil reinforcements, restoring original strength and load-bearing capacity.
• Versatile material compatibility: suitable for applications across common substrates where thread repair and reinforcement are needed, from aluminum to steel.

Use cases you’ll encounter with the Baer Heli Coil Tap include reviving stripped threads in engine blocks, intake manifolds, brackets, transmission housings, and other components where a retrofit with a Heli-Coil insert is the most practical long-term solution. The result is a repair that not only restores the original fit but often exceeds it in resistance to fatigue and vibration over the life of the part.

What makes this tap stand out is its focus on consistency and longevity. The bottoming design minimizes the risk of incomplete threads, while the 3/8 x 26 threading aligns with readily available inserts, reducing downtime in repair shops and on the bench. When you need repeatable results—every time—this tool delivers.

Practical tips for best results: - Use a sharp, clean drill and ensure the hole is properly deburred before tapping. - Lubricate during tapping to reduce wear and produce smoother thread cuts. - Tap in a steady, clockwise motion with light to moderate pressure; back off periodically to clear chips. - After tapping, inspect threads for straightness and cleanliness before installing the Heli-Coil insert. - Follow insert manufacturer instructions for seating depth and installation torque to achieve optimum retention.
