Fit, function & longevity of the TA Series Tapping Arm comes from simple yet durable design and our tap arm systems come at a very practical price. Precision machining and hand fitting of components during assembly make ETA tap arms the Swiss watch of tapping arms. TA Series Tapping Arms are designed, machined and assembled in the United States by Americans. We back this statement with a 3 year warranty against wear-out. These floating tap arms offer the most flex ability in a tap arm. It's easy to adjust our tapping machine to float up and out of the way between holes or when not in use or you can set the float tap arm to suspend perfectly in any position. Threads are formed or cut without torque reaction because the tap arm keeps the tool from spinning. Bilz tap chuck and Bilz tap adapters used in our tapping arm systems are interchangeable with T.M. Smith, Flexarm, Collis, Universal, Lyndex, 3Arm, Accupro, Centaur, Emuge, Erickson, Parlec, and others.
