Product Description
The Heli-Coil® 3697-4 is a replacement tool punch engineered for use with manual and pneumatic tang break-off tools. Designed specifically for 1/4" tanged insert tooling (such as model series 3695-4 and 4238-4), this precision component drives efficient driving tang removal following insert installation in 1/4-20 UNC and 1/4-28 UNF tapped holes. Constructed from hardened alloy steel, it provides outstanding impact resistance and long operational durability, ensuring clean, square tang breaks without damaging the installed internal wire threads.
Replacement Tool Punch acts as the primary impact contact pin within tanged insert break-off tooling.
Hardened Alloy Steel Construction delivers high wear resistance and extended service life under repeated mechanical strikes.
Compatible with 1/4" Break-Off Tools designed specifically to fit 1/4" (1/4-20 UNC and 1/4-28 UNF) tang removal tool assemblies.
Precision Impact Tip transmits sharp, focused force to break driving tangs cleanly at the notch without thread distortion.
Essential Maintenance Part enables rapid tooling reconditioning to maintain high productivity and consistent assembly performance.
