It’s designed to speed up jobsite work and extend tool life without sacrificing accuracy.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the eccentric cone improve flare quality?\u003c\/h3\u003e\n\u003cp\u003eThe eccentric cone geometry centers and forms the tubing into a true 45-degree flare, minimizing uneven lip formation and potential seal problems. Because the shaping action is optimized for common HVAC tubing sizes, the result is a uniform flare face that mates cleanly with fittings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eProduces consistent 45° flares across specified tube sizes\u003c\/li\u003e\n  \u003cli\u003eReduces uneven edges that cause leaks\u003c\/li\u003e\n  \u003cli\u003eWorks with both soft and work-hardened copper\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the internal clutch protect against on the NTF66?\u003c\/h3\u003e\n\u003cp\u003eThe built-in clutch limits applied torque so the operator can’t over-tighten while forming the flare.
