20C Dead Length Assembly without Inner Collet

Hardinge® Dead-Length Step Chucks will accommodate larger chucking diameters. Shoulders and faces can be machined to exact length, regardless of OD variations with the Hardinge Dead-Length Step Chucks. The low-cost step chuck has a soft face and pilot hole to permit boring to size in the machine spindle for exacting concentricity. The step chuck is pinned to the outer collet to maintain location and original bored accuracy. Dead-Length Step Chucks can be used on all machines and attachments with a 5C/16C spindle and draw bar. The outer collet, solid stop, spring and nut are inter-changeable between the Dead-Length Collet and the Dead-Length 2" Step Chuck. The complete assembly is a one time purchase; after that, buy the step chuck only.
