Product Description
The HELI-COIL 18551-04-15 is a high-precision power tool front end assembly (FEA) designed specifically for the automated installation of #4-40 UNC tangless wire thread inserts. Engineered to integrate directly with Heli-Coil electronic and pneumatic driver systems, this durable steel front end assembly provides optimal support and guidance for strip-feed and fine-thread inserts, ensuring accurate depth placement, efficient insert pre-winding, and seamless driver reversal without generating foreign object debris or damaging parent materials.
Power Driver Compatibility attaches directly to Heli-Coil electronic and pneumatic power driver units for rapid, high-volume insert installation.
Optimized for Strip-Feed Inserts engineered to guide fine-thread and strip-fed tangless inserts smoothly into pre-tapped holes without jamming.
Tangless Drive Pre-Winding cleanly engages the drive notches of #4-40 UNC tangless inserts to facilitate rapid, non-destructive insertion.
Hardened Steel Construction built from high-grade tool steel components to withstand continuous torque loads and minimize industrial wear.
Precision Alignment Mechanics ensures exact concentricity with host material tapped holes to prevent cross-threading and reduce operator fatigue.
