#10 Knurling, Facing and Turning Holder: For turning and facing as well as knurling. The holder is supplied with a set of high speed precision ground and lapped medium diamond knurls. Holder comes with two knurls.
#19 Adjustable Knurling Holder: Self-centering and is adjusted by means of a threaded spindle with left and right hand threads, providing the ideal near-vertical axis approach angle for a wide range of stock diameters. Spindle and cross-slide pressure are minimal, thus knurling of thin wall tubing is easily performed. It is designed for use in any standard turret tool post or other open-slot holder. It is also available in dovetail mounting (series 19) to fit Aloris tool posts. Precision ground 3/4″ O.D. x 3/8″ wide, high-speed medium diamond knurls are supplied unless otherwise specified.
