Arrived and ready for local postage

The Big ACCU-820 Auto Tapper is a precision-engineered tapping attachment designed for smooth, consistent thread production in lathes and drilling machines. With its Morse Taper No. 3 shank and integrated reversing clutch, it automatically backs the tap out once the desired depth is reached, reducing operator input and protecting both the tap and the workpiece.

The included side stabilising arm keeps the attachment aligned during operation, improving accuracy and reducing the risk of deflection. This unit comes with four quick-change collets to cover a variety of tap sizes, making it suitable for a range of threading tasks.
