Description
When you need dependable, repair-ready threads, the Baer Heli Coil Tap is your go-to tool for precise, durable results. Designed for metric M6 x 1 applications, this spiral point tap expertly creates clean internal threads that welcome Heli-Coil wire inserts and reinforced fasteners, restoring strength where it matters most.

Key features that set the Baer Heli Coil Tap apart:
- Metric compatibility: Specifically engineered for M6 x 1 threads, ensuring a perfect fit for standard Heli-Coil inserts and common panel, chassis, and machinery components.
- Spiral Point (STI) geometry: Optimized to push chips forward, reduce binding, and deliver smooth, straight cutting action in through-holes and plates alike.
- Built for durability: Constructed with robust tooling metallurgy and precise ground geometry to withstand repeated use in steel, aluminum, and other common substrates.
- Consistent thread depth and alignment: Delivers uniform threads that improve insert seating, torque tolerance, and long-term holding power.
- Repair and reinforcement ready: Perfect for restoring stripped or damaged threads and providing reliable anchors for high-stress fasteners.
Ideal for a wide range of applications—from automotive and industrial equipment to home workshop repairs—the Baer Heli Coil Tap empowers technicians and DIYers to recover critical joints without the cost of replacement parts. Use it to prepare a hole for a Heli-Coil insert, rebuild damaged threads in thin-walled components, or create reinforced threads in new assemblies that demand durability under vibration and load.
How to use (quick guide):
- Secure the workpiece and select the correct hole size for your M6 x 1 thread.
- Lubricate lightly to minimize tool wear and ensure a clean cut.
- Start the tap square to the workpiece and apply steady, even pressure as you cut threads through the material.
- Break or deburr the hole edges, then clean away chips before seating the Heli-Coil insert.
- Verify the thread engagement with a matching fastener to ensure proper torque and holding power.
Compared to generic taps, the Baer Heli Coil Tap is purpose-built for precision thread repairs and insert-ready threads. Its design prioritizes straightness, chip evacuation, and repeatable performance—so you get reliable results, time after time, even in challenging materials or damaged holes.
