Uniweld’s UDFT Deluxe Flaring Tool is specifically designed to meet R-410A flaring specifications and all 45° flares for tubing. The internal breakaway clutch that disengages when a flare is completed prevents over-flaring and crushing the copper tubing. The 3/4?-12 point reversible ratchet wrench included reduces the amount of effort required to manually flare in a confined workspace. The 3/8? square drive can be used with a cordless electric drill for faster flaring. Features an eccentric off-center cone that spins on an axis and rolls out a perfectly uniform 45° flare with a burnished flare surface.
