Parlec C50-18DC8 Collet Chuck DA180 CAT50 Taper Shank

Product Description

The PARLEC C50-18DC8 is a DA180 double angle collet chuck designed for CNC machining centers requiring precise tool holding on a CAT50 taper shank interface. It accepts collets ranging from 0.031 to 0.75 inches in capacity, covering a wide range of cutting tool shank diameters in a single chuck body. The chuck delivers a total indicator runout (TIR) of 0.0004 inches, supporting close-tolerance milling, drilling, and reaming operations. Through-spindle coolant is supported, directing fluid directly to the cutting edge for improved chip evacuation and tool life. Licensed machinists and CNC setup technicians are the primary installers of this toolholder.

This collet chuck is suited for production machining environments where DA180 series collets are the shop standard. The CAT50 taper shank seats in CAT50-compatible spindles commonly found on full-size vertical and horizontal machining centers. The 8.15 inches projection and 12.15 inches overall length make it appropriate for applications requiring reach into deep pockets or fixtures. Through-spindle coolant compatibility makes it a practical choice for high-speed cutting of ferrous and non-ferrous materials where coolant delivery at the tip is required.

Compatibility

Designed for use with DA180 series double angle collets. Requires a CAT50-compatible spindle. Collet capacity range of 0.031 to 0.75 inches covers standard cutting tool shank sizes used with this collet system.

Installation Notes

Installation and removal should be performed by a qualified machinist or CNC setup technician following the machine tool manufacturer's toolholder torque and drawbar procedures. Power down and lock out the machining center spindle before mounting or removing the toolholder. Inspect the taper shank and spindle bore for chips, nicks, or contamination before seating; any debris will affect runout and retention. Verify coolant passages are clear and that through-coolant fittings are properly connected before resuming cutting operations.
