Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M11 x 1.5

When threads fail, you don’t want guesswork—you want precision that restores strength. The Baer Heli Coil Tap is the bottoming tap designed for seamless integration with wire thread inserts, delivering reliable, high-performance repairs and reinforcements for internal threads. Engineered for durability and accuracy, this tap is your trusted partner for M11 x 1.5 applications across metal parts and assemblies.

Precision that lasts: why the Baer Heli Coil Tap stands out

Key features built for real-world use:

• Bottoming tap design (STI) ensures the cutting path reaches full thread depth in one clean pass, producing a precise, bottomed thread every time—ideal for secure insert seating.
• Metric M11 x 1.5 compatibility—perfect for restoring standard fastener threads and maintaining consistent torque and pull-out resistance in a variety of components.
• HSSG construction—high-speed steel ground for enhanced wear resistance, delivering longer tool life in demanding materials and repeated use.
• Optimized for wire thread inserts—designed to pair with Helicoil-style inserts, delivering stronger, more durable repairs that feel like the original threads.

Practical benefits you’ll notice on the shop floor

• Restore damaged threads in aluminum, steel, and other common metals with confident accuracy, reducing the need for costly part replacements.
• Improve repair longevity by creating a stable, reinforced thread that behaves like the factory spec under load.
• Minimize insertion issues—less cross-threading and easier alignment when seating a wire insert.

Who benefits most

• Machine shops, automotive repair facilities, and manufacturing environments where reliable thread restoration is critical.
• DIY enthusiasts tackling mid-tier repairs where professional-grade tooling makes a visible difference.
• Anyone working with common M11 x 1.5 fasteners who needs a durable, repeatable tapping solution.

Best-practice tips for peak performance

• Prepare the hole: deburr and clean to ensure smooth cutting and optimal insert seating.
• Apply a light cutting oil to reduce heat and extend tap life; maintain steady, perpendicular pressure for clean threads.
• Choose the correct insert size for M11 x 1.5 to achieve a snug, secure fit with maximum holding power.
• Follow manufacturer torque specs for the installed fastener to maintain thread integrity over time.
