		Single Taper Flanged Collet Arbor Assembly (28) Application: • Used for most internal workholding applications. • Pull back clamping action contributes to the positive location of the workpiece against the workstop. • Repeatability: .0005" T.I.R. • Used for most internal workholding applications when the straight bore has an adjacent locating surface. • Inherent pull back clamping action contributes to the positive location of the workpiece against the workstop. • Workstops are designed for individual applications.




		Double Taper Flanged Collet Arbor Assembly (28) Application: • Used for parts with longer bores or stepped internal diameters. • Collets tend to conform to slightly tapered bores. • Ideal for gripping in blind bores. • Pull back action for positive location of the workpiece against the work stop. • Repeatability: .0005" T.I.R. • Work stops are designed for individual applications.




		Slow Taper Flanged Collet Arbor Assembly (32) Application: • Used for internal workholding of parts with longer bores. • Higher grip force compared to single and double taper arbors. • Longer collet length allows for greater expansion. • Pull back action for length control. • Repeatability: .0005" T.I.R. • Higher gripping force than single or double taper collets. • Work stops are designed for individual applications. • Stocked Size Range: On Availability




		Hi-Torque Flanged Collet Arbor Assembly (13) Application: • Used primarily for rough turning operations where high gripping forces are required. • Widely used for small diameters under .50 inch. • Permits gripping to the full length of blind bores. • Up to three times the gripping force of other collet arbors. • Pull back action for length control. • Work stops are designed to suit individual applications. • Repeatability: .0005" T.I.R.




		Between Centers Collet Arbor (8) Application: • Ideally suited for grinding, turning and inspection operations that require locating between machine centers. • Each end of the double taper collet conforms to the bore for positive gripping. • The extended arbor body is knurled to make handling easy. • Arranged with a flat for mounting a drive dog. • Pull back action for length control. • Whistle notch in the arbor body permits mounting of a work stop. • Repeatability: .0005" T.I.R. • Stocked Size Range: .25" to 7.00" dia • Max. Expansion: .006" to 030"
