The RIDGID 458R (83037) Precision Ratcheting Flare Tool is designed to form 45 degree SAE flares with minimum effort. A reversible ratchet is built into the feed screw handle, enabling it to turn easily and require less motion and effort than a standard handle. The flare tool is also equipped with a hardened steel flaring cone, which is eccentrically mounted in the needle bearings. The cone produces a rolling action for an even metal flow, resulting in uniform flare walls without galling. A clutch automatically releases to iron and smooth the flare after it is completed. The 458R Flare Tool will flare steel, stainless steel, hard copper and brass tubing through a wall thickness of 0.035″ (0.9 mm).
