The Baer Heli Coil Tap is your precision partner for restoring and reinforcing threaded holes with wire thread inserts. This Spiral Flute STI tap is specifically engineered for the metric M14 x 1.25 sizing, the standard pitch used by helicoil-style inserts, so you can trust a perfect fit every time.

Designed to work seamlessly with common wire thread inserts—Helicoil, Recoil, Perma-Coil and other premium brands—the tap’s geometry is optimized to produce clean, true threads that accept the insert securely and align perfectly with the bolt or stud that will thread into them. The spiral flute design isn’t just for show; it actively evacuates chips as you cut, reducing clogging and helping you reach full thread depth in fewer passes. A proper bottoming chamfer and consistent lead ensure a square, accurate thread form that minimizes cross-threading and maximizes insert engagement.

Across a wide range of materials—ferrous and non-ferrous—the Baer Heli Coil Tap delivers dependable results when repairing damaged threads or reinforcing soft housings. Whether you’re servicing engine blocks, transmission housings, aluminum blocks, or steel components, this tap creates the robust internal threads that your helicoil insert needs to perform under load. The M14 x 1.25 thread pitch is a staple in many repair and reinforcement scenarios, making this tool a trusted addition to professional shops and well-equipped home workshops alike.

Practical guidance for best results:

• Pre-bore or pre-tap with the correct insert-size drill to ensure precise hole dimensions before tapping.
• Lubricate the tap and work slowly to maintain cutting control and thread accuracy.
• Align the tap perpendicular to the workpiece to avoid misalignment and cross-threading; back off to break chips as needed.
• Test with a helicoil insert or the intended screw to confirm proper engagement and depth before final assembly.

Why choose Baer for thread repair and reinforcement? This Heli Coil Tap emphasizes durable construction and precise geometry tailored to the STI insert system. The result is repeatable, reliable thread formation that supports strong, long-lasting inserts, reducing downtime and extending the life of critical components.
