TAPPER CHUCK
Most suitable for tapping gas threads, blind-end threads and light alloys. When normal rotation of machine is stopped at specified position, the Tapper Chuck runs idle after progressing by its elongation (4mm for ZL12 type). Simply rotate the machine in the reverse direction, and the tap depth will be made uniform within a high-precision.
