Series 700 D, 700 E, 700 F, 700 G - Large Tap Extension

These jumbo-size tools have a standard length of 6 and 12 inches (other lengths available on special order) and employ the exclusive RITMAR Collet Grip which enables them to be used for extension tapping with machine tools, as well as by hand, and permits dull or broken taps to be changed quickly and easily without the use of hand tools.
