Baer Heli Coil Tap — Bottoming Tap (STI) for Metric M22 x 2 thread repairs and reinforcements. When paired with Heli-Coil wire thread inserts, this precision tool restores damaged holes with rock-solid threads, delivering reliable performance in automotive, industrial, and machine-shop work.

Why this tap matters

Designed specifically for Heli-Coil inserts, the STI bottoming tap cuts clean, accurate M22 x 2 threads all the way to the bottom of the hole. This full-depth thread form ensures the insert seats squarely and remains secure under vibration and load. In practice, that means fewer strip-outs, longer service life for critical components, and easier future maintenance.

Key features that translate to real-world results

• Bottoming geometry for complete depth: engineered to reach the full thread length in blind holes, so your Heli-Coil insert seats properly and performs as intended.
• STI-optimized tapping for inserts: part numbers and tooling align with Helicoil STI systems, making alignment predictable and installation smooth.
• Metric precision, M22 x 2: sized for common high-strength applications where larger repair threads are required. (M22 x 2 is a standard size you’ll encounter in heavy machinery and automotive components.)
• Manufactured for durability: built from tough, high-speed steel formulations to resist wear and provide consistent cuts across multiple repairs. (Supports the long-term reliability you need in demanding environments.)
• Cleaner threads, quicker repairs: refined flute geometry minimizes burrs and chatter, helping you finish faster with professional-grade results.

Who should consider the Baer Heli Coil Tap

This tap is ideal for machinists, automotive technicians, and maintenance crews who regularly restore stripped or damaged threads in metals where insert reinforcements are preferred over oversized, costly replacements. It’s especially valuable when you need to:

• Repair stripped M22 x 2 holes in aluminum blocks, engine components, or chassis parts.
• Prepare holes for reliable Heli-Coil inserts that restore original strength and torque capabilities.
• Perform consistent, repeatable threading in production or repair environments where downtime matters.

Practical tips for best results

• Use appropriate cutting fluid and steady, straight torque to maintain alignment with the hole axis.
• Correct drill hole size and deburr before tapping to prevent threading defects.
• Follow with a Heli-Coil insert installation for a professional repair that restores original performance.
• Store taps in a clean, dry environment to preserve edge geometry and tool life.

For reference, industry guides and supplier catalogs discuss STI taps and M22 x 2 bottoming options designed for wire insert systems, underscoring the compatibility and precision you get with this tooling standard. This reinforces why a dedicated Heli-Coil STI bottoming tap is a smart, long-term choice for reliable thread restoration.
