Description
The Baer Heli Coil Tap is the precision-bottoming tool you reach for whenever you need dependable thread repairs and reinforced holes with Heli-Coil wire inserts. Designed for No. 2 UNC applications and sized at 56 length, this bottoming tap (STI) drives threads to the very bottom of the hole, delivering a clean, true start every time.
Why this Baer tap stands out:
- Bottoming geometry for full-depth threads – ensures the insert seats correctly and evenly, maximizing grip and long-term durability.
- UNC No. 2 x 56 specification matched—easy to pair with common repair kits and standard insert systems.
- Rugged, precision-made construction designed for repeated use in steel, aluminum, and other common engineering alloys.
- Efficient, burr-free tapping supports quick workups in manufacturing and maintenance environments, reducing downtime.
- Heli-Coil compatibility ideal for restoring stripped threads or reinforcing high-stress holes where insert performance matters.
Ideal for machinists, maintenance technicians, and DIY enthusiasts, this tap helps you recover critical components—from engine blocks to housings and structural parts—without resorting to oversized repairs or costly replacements. It’s the reliable, purpose-built solution for thread repair and reinforcement that keeps assemblies moving with confidence.
Practical tips for best results: use the correct pre-drill size for No. 2 UNC, apply a light lubrication, maintain steady, straight cuts, and clean the hole thoroughly after tapping before inserting the Heli-Coil to ensure optimal engagement and longevity.
