The Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - Metric - M30 x 1.5 is a professional-grade tool designed for precise thread repairs and reinforced, long-lasting threads. Built to support reliable insert installations, this bottoming tap ensures clean, accurate engagement when working with helicoil/METRIC inserts in a variety of metals.

Key capabilities that matter in the shop

• Full-depth tapping for blind holes. Bottoming taps cut threads all the way to the bottom of a hole, creating a solid seat for a helicoil insert and maximizing withdrawal strength. This is essential when you can’t access the back side of the part.
• Metric precision for M30 x 1.5 threads. The M30 x 1.5 size denotes a 30 mm nominal diameter with a 1.5 mm thread pitch, a common specification for robust, load-bearing assemblies.
• Optimized for helicoil/wire thread inserts. This tap is designed to work in harmony with standard Helicoil-style inserts, enabling repeatable, dependable thread repairs and reinforced threads.

Why this tap matters in real-world applications

When you’re rebuilding worn or striped threads in critical components—auto, machinery housings, or equipment with high vibration—the combination of a bottoming tap and a helicoil insert restores thread strength far beyond what a damaged hole can offer. The Baer Heli Coil Tap helps you achieve a precise, straight thread path that aligns perfectly with the insert, reducing the chance of cross-threading and improving overall assembly reliability.

Usage scenarios and best practices

• Repair degraded threads in aluminum or steel parts where fastener load matters, such as engine supports, brackets, or mounting points.
• Prepare a blind hole for a helicoil insert by drilling to the insert’s recommended size, then finish with a bottoming tap to ensure full-depth threads for optimal insert seating.
• Pair with the appropriate helicoil insert kit to restore original strength and ensure consistent load transfer through the repaired thread.

Designed for durability and long service life, this Baer Heli Coil Tap provides dependable performance across repetitive repairs and maintenance cycles. It’s the tool you reach for when precision, depth, and reliability are non-negotiable in threaded repairs.
