Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - BSW - 7/16 x 14

Baer Heli Coil Tap — the trusted bottoming tap designed to work seamlessly with wire thread inserts for durable, reliable repairs and reinforcements. Sized for BSW threads at 7/16 x 14, this tap is built to form precise, true threads that accept helicoil inserts with confidence and ease.

Why this bottoming tap stands out

• Full-depth tapping for blind holes. The bottoming geometry reaches the full thread depth every time, ensuring clean, complete threads right to the bottom of the hole.
• Rugged, precise construction. Engineered for durability in challenging materials, delivering consistent threadforms that resist wear during repeated insert installations.
• Optimized for Heli-Coil style inserts. When paired with wire thread inserts, you get reinforced threads that tolerate higher loads and resist pull-out in critical components.
• Accurate size and form. Specifically matched to BSW specifications (7/16-14) to ensure compatibility with common British Standard Whitworth threads and related tooling.

What this tap can do for you

• Repair stripped or damaged threads. Restore strong engagement in soft metals, castings, and other common substrates where a repair is needed without replacing the entire part.
• Reinforce high-stress holes. Reinforcement with Heli-Coil inserts provides increased torque capacity and vibration resistance in automotive, machinery, and industrial equipment.
• Extend component life. Rebuilt threads reduce the need for costly replacements and downtime, delivering quick turnaround in maintenance scenarios.

Ideal for

• Automotive repair technicians tackling stripped cylinders, engine blocks, or bracket holes.
• Machinists and hobbyists performing equipment maintenance or restorations where robust, repeatable threads are essential.
• Industrial technicians refurbishing housings, tooling, and frames that see frequent disassembly.

Practical tips for best results

• Use appropriate tapping fluid and maintain steady cutting pressure to reduce heat and wear.
• Align the tap carefully with the hole axis to preserve thread accuracy and avoid cross-threading.
• 清洁 chips frequently to prevent binding and ensure a clean thread pattern for the insert.
• Pair with compatible Helicoil inserts for reinforced threads that resist stripping in high-load applications.

Engineered to deliver consistent performance in repairs and reinforcements, the Baer Heli Coil Tap helps you achieve professional, factory-like threads with confidence. Whether you’re restoring legacy equipment or bolstering new assemblies, this bottoming tap is a precise, dependable choice for 7/16-14 BSW threaded holes.
