These sets of soft jaws are available in two sizes, 100 and 125mm to suit the same size chucks fitted to the Axminster Engineer and CNC Technology Series machines. Supplied as a set of three, they simply replace the standard hardened jaws supplied with the chuck.
Soft jaws have many uses, the ability to be machined on the lathe perfectly concentrically to grip thin materials or tubes, "wrap" around thin section washers or spacers by shallow boring, or to grip any peculiarly shaped items. They also leave much less marking on the workpiece than found when using hardened jaws.
100mm set suits the C4, SC4, KC4 and iKC4 lathes; the 125mm set suits the C6, SC6, KC6S and iKC6 lathes.
