Description

Baer Heli Coil Tap — Precision Spiral Point Tap (STI) for Metric M16 x 2 Thread Repairs
The Baer Heli Coil Tap is the dedicated STI tool you reach for when you need flawless, repair-friendly threads that can accept Heli-Coil wire thread inserts with confidence. Designed specifically for metric M16 x 2 holes, this tap cuts true, repeatable threads that restore structural integrity and load-bearing capability in a variety of materials—from engineered aluminum to tough steels.
- Spiral Point (STI) geometry delivers forward-chip evacuation and cleaner thread engagement, reducing the chance of burrs and chatter even on tougher substrates. This means quicker, more predictable tapping with fewer reworks.
- Durable HSSE-grade steel built for repeated use in demanding shop environments. Sharp cutting edges stay true longer, helping you maintain consistent thread quality over time.
- Metric M16 x 2 precision ensures perfect compatibility with standard Heli-Coil inserts and mating hardware, making it the reliable choice for restoring stripped threads that must meet exact specifications.
- Repair and reinforcement in one step by creating the ideal foundation for a durable insert, so worn holes regain original strength and resist future cross-threading or failure under load.
- Versatile performance across automotive, industrial, and machinery applications—ideal for repairing threaded holes in engine blocks, housings, brackets, and precision components where dependable threads matter most.
- Professional-grade results for DIY and shops—achieve consistent, high-quality threads that turnout after installation, reducing downtime and extending component life.
How to use (quick guide):
- Drill the recommended pilot size for M16 x 2 holes, following insert kit guidelines. Ensure straight, centered alignment.
- Apply a light cutting fluid or oil to reduce heat and prolong blade life.
- Begin tapping with steady, evenly applied pressure. Maintain alignment and avoid twisting or misfeeding to prevent tool breakage.
- Tap to the full depth specified for the insert, then remove the tap and clean the hole of chips and debris.
- Install the Heli-Coil wire thread insert with the appropriate installer tool to complete the repair or reinforcement.
Why choose the Baer Heli Coil Tap for your thread-repair projects? It’s built to deliver predictable, repeatable results when you need to recover strength in worn holes without compromising precision. Whether you’re refreshing critical automotive threads, restoring machinery housings, or rebuilding structural components, this tap provides the reliability and consistency that professional shops and serious DIYers demand.
