The Baer Heli Coil Tap — Wire Thread Insert — Bottoming Tap (STI) in Metric M16 x 1.5 is a precision-engineered tool designed for durable, reliable thread repairs and reinforcements. Built for demanding metalwork, this tap delivers clean, accurate threads that form the foundation for strong helicoil installations in a wide range of materials.

Why this Heli Coil Tap delivers real value

• Exact metric performance with M16 x 1.5 pitch, ensuring perfect compatibility with standard Helicoil inserts for consistent repair results.
• Bottoming design allows full-depth threading in blind holes, guaranteeing a secure seat for the wire-thread insert and preventing premature pull-out under load.
• Durable construction typically crafted from high-speed steel (HSS) for excellent wear resistance, heat tolerance, and long service life in challenging alloys.
• Precision finish ground flutes and a tight tolerance profile for smooth cutting, reduced chatter, and clean thread creation in a single pass.
• Versatile utility ideal for automotive, machinery, and general repair applications where damaged, stripped, or weakened threads need restoration with a helicoil insert.

How it solves common threading challenges

When threads are damaged or stripped, the integrity of a fastener joint is compromised. This Baer Heli Coil Tap enables you to:

• Restore damaged thread surfaces in metals like aluminum and steel without replacing the entire component.
• Create dependable, shear-resistant threads that work in tandem with helicoil inserts to reinforce soft or fatigue-prone holes.
• Achieve flush seating for inserts, reducing protrusion and ensuring smooth, unobstructed bolt engagement.

Practical use cases

• Repairing stripped engine blocks, cylinder heads, and critical brackets where strong, reliable threads are essential.
• Reconstructing damaged mounting points on machinery housings, transmission components, and chassis brackets.
• Renovating threaded holes in DIY automotive projects, fabrication work, and precision equipment assemblies.

Tips for best results

• Match the tap size exactly to the helicoil insert you plan to use (M16 x 1.5) for optimal fit and performance.
• Apply a light cutting oil or penetrating lubricant to reduce heat and extend tool life during tapping.
• Ensure straight, perpendicular alignment to the hole to avoid cross-threading or tool breakage.
• Clean the hole thoroughly after tapping and install the helicoil insert according to the standard helicoil installation procedure for a secure, lasting repair.

Whether you’re a professional machinist or a serious hobbyist, the Baer Heli Coil Tap provides reliable, repeatable results when repairing or reinforcing threaded holes. Invest in a tool that helps you restore function, extend part life, and maintain the integrity of critical assemblies with confidence.
