4. NAVAC NTF66 45-Degree Flaring Tool – Eccentric Cone, Internal Clutch
The most common buyer complaint about this manual tool involves the physical strain during high-volume jobs, but the internal clutch prevents over-tightening remarkably well. I find manual control reassuring when working with delicate aluminum lines.
It bridges the gap between cheap generic sets and high-end power tools. You trade battery convenience for absolute tactile feedback.
Users rely on the built-in clutch to prevent cracked tubing from excessive force.

5. Hilmor 1838952 Orbital Flare 3/16” – 3/4”, HVAC and Refrigeration Flaring Tool for Copper, Aluminum, Steel and Brass, Gray/Black
Compared to the manual NAVAC model above, this unit leans into a much heavier orbital rolling action designed for rugged commercial environments. I consider this the tank of the group, built specifically to survive drops and abuse.
It handles multiple metals including steel and brass with ease. You will carry a heavier tool in your bag, but the durability justifies the extra weight.
Professionals praise the multi-metal capability for heavy-duty industrial applications.
Users report that the orbital rolling motion creates exceptionally smooth flare walls.
Some feedback notes the bulkier frame feels heavy in a crowded tool belt.

Choosing Between Them
If you want the absolute best performance, choose the NAVAC NEF6LM for its unmatched speed on the jobsite, though premium power tools demand a hefty upfront investment. For budget-conscious buyers, the Super Stars 5-in-1 Kit offers solid value, while heavy-duty users should look directly at the Hilmor Orbital for rugged multi-metal work.
Keep in mind that motorized tools require strict charging routines to remain useful on remote service calls. If you stick with manual options, prepare to invest some physical effort into every single line you prep.
