Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M6 x 1

The Baer Heli Coil Tap is the dedicated bottoming tap you reach for when a trusted thread repair becomes non-negotiable. Engineered for durability and precision, this metric M6 x 1 bottoming tap (STI) delivers clean, true-thread formation every time you prepare a hole for a Heli-Coil wire thread insert.

Key advantages that matter in real-world repairs:

• Bottoming precision for full-depth threads. The tapping geometry reaches all the way to the bottom of blind holes, ensuring a complete, uniform thread with no undercut—perfect for secure insert engagement.
• Durable HSS construction. Built to withstand repeated use across steel, aluminum, and other common substrates, so one tool performs reliably in the shop and in-field repairs.
• Optimized for inserts. Specifically designed to pair with Heli-Coil wire thread inserts, providing accurate thread form and consistent insert seating for reinforced, load-bearing threads.
• Consistent thread pitch and fit. Metric M6 x 1 threads are formed with tight tolerances to ensure smooth insertion of the coil insert and predictable torque during installation.

Who benefits most from this tap? Technicians, machinists, and DIY enthusiasts tackling stripped or undersized threads in mechanical assemblies, automotive components, or equipment housings. It’s ideal for reinforcing critical mounting points, repairing damaged internal threads, or preparing holes to accept high-strength inserts that restore original performance and longevity.

Practical use tips to get the best results:

• Lubricate the tap with a light cutting fluid to reduce friction and extend tool life.
• Align the tap squarely to the hole and use steady, clockwise turns with gentle back-off to break chips and prevent cross-threading.
• Tap to the full depth of the hole for blind applications, then install the Heli-Coil insert per the kit instructions to achieve a secure, wear-resistant thread.

Designed to be the go-to solution when thread integrity matters, the Baer Heli Coil Tap combines reliable performance with the precision you need for long-lasting repairs. Add it to your toolkit and experience repeatable results that you can count on, whether you’re refurbishing a motorcycle frame, a machine housing, or a precision component.
