This precision tool provides smooth, uniform flares with minimum effort. The new ratcheting feed screw handle turns easily and requires less motion and effort than a standard handle. Hardened steel flaring cone, eccentrically mounted in needle bearings, produces rolling action for even metal flow, giving uniform flare walls without galling. For aluminium, soft copper, steel, stainless steel, hard copper and brass. Type: 45° SAE Flares.
