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. 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. Movement of ETA tapping arms is virtually effortless. Threads are formed or cut without torque reaction because the tap arm keeps the tool from spinning. Once set up properly, the tap arm machine also guides the tap and keeps it in perfect alignment with the hole.
