| | | GK Self-Feeding (Pafix) Tap Holders provide automatic thread-length control. The tap holders eliminate the need to perfectly match the feed rate to the thread pitch, minimizing tool breakage and "pulled" or "squeezed" threads. The holders have a 5/s" (15.87mm) shank diameter that allows it to be mounted into a round shank tool holder: Thread length is controlled internally with an adjusting ring in .01" (.25mm) increments. A driver is used in the holder to accommodate the square of the tap shank, providing a positive drive. A collet is used to centralize and hold the tap in the holder Tap holders are supplied standard with the necessary collets and drivers. Replacement tap collets and drivers are sold separately The same unit is used for left- and right-hand industrial taps. The GKII and GKI2 models come with 3 tap collets and 4 drivers. The GK2I and GK22 come with 6 tap collets and 6 drivers. | | |
