Baer Heli Coil Tap — Wire Thread Insert — Bottoming Tap (STI) — Metric — M14 x 1.5 is engineered to deliver precise, dependable internal threads for repairing and reinforcing critical holes. When integrity matters, this bottoming tap ensures clean, full-depth threads that pair seamlessly with standard HeliCoil wire thread inserts, delivering durable performance across a range of applications.

Why this Baer tap stands out

• Rugged HSS-G construction: built to resist wear and maintain accurate thread geometry through repeated use in steel, aluminum, and other common materials.
• Bottoming tap design (STI): taps to the very bottom of the hole for full-depth threads, essential for secure coil insert engagement and long-term reliability.
• Metric accuracy: M14 x 1.5 thread form compatible with the industry-standard HeliCoil inserts, making repairs predictable and repeatable.
• Efficient chip control: optimized flute geometry promotes smooth cutting and easy chip evacuation, even in blind holes.
• Durable finish: engineered finish provides wear resistance, extending tool life in demanding repair work.
• Repair-focused versatility: ideal for restoring stripped threads or reinforcing high-stress mounting holes in automotive, industrial, and machinery components.

Ideal use cases

When a thread has worn away or damaged a mounting hole, use this tap with a HeliCoil insert kit to recreate strong, vibration-resistant threads. It’s particularly valuable for engine blocks, housings, and structurally important brackets where reliable fastening is critical. The tool’s precision ensures alignment and stall-free operation, reducing the risk of cross-threading during installation.

Practical tips for best results

Prepare the hole cleanly and deburr the edge before tapping. Use the correct drill size and guides from your HeliCoil kit to ensure straight, concentric threading. Cut with the bottoming tap to the intended depth, then clean the threads and install the coil insert per the kit instructions. With proper technique, you’ll achieve durable, repair-ready threads that resist loosening in demanding service conditions.
