Quick change tool post and holders for manual lathes of 8 to 20 inch swing, in piston type and wedge type, with six holder families. Size goes by the lathe swing, not by the tool: a QCTP — or just a toolpost — is bought to the machine, and the commonly used 250 series numbering lines up with the AXA, BXA, CXA and CA size classes; below those sits an 8 inch size that is wedge type only. A piston type post pushes the holder outward against one dovetail face, while a wedge type draws it evenly against both, which clamps more uniformly. Wedge covers all five sizes, piston the four larger. Holders cover turning and facing, boring, parting and knurling, plus Morse taper drilling holders in MS2, MS3 and MS4, and take tool bits from 3/16 to 1 inch. Changing tools is a lever throw instead of a re-shim, which is the point of the system. Model numbers, swing ranges and holder dimensions are in the chart below.
