Parlec EXT750 Collet Chuck Double Angle DA200 Straight Shank

Product Description

The PARLEC EXT750 is a straight-shank collet chuck designed for precision machining applications using the Double Angle DA200 collet system. It accepts collets from 0.0313 to 0.3906 inches in capacity, covering a broad range of tooling diameters for milling, drilling, and reaming operations. The chuck features through-coolant capability, delivering cutting fluid directly to the tool tip for improved chip evacuation and tool life. With a TIR of 0.0004 inches, this chuck is suited for applications where runout control is critical. Licensed machinists and CNC setup technicians are the primary installers of this type of tooling component.

This collet chuck is intended for use in machining centers and CNC milling applications where the DA200 Double Angle collet system is specified. The straight shank measures 0.75 inches in diameter with a shank length of 5.50 inches, making it compatible with standard straight-bore tool holders and spindle adapters. The overall length of 7.186 inches and a projection of 1.686 inches suit it for setups requiring moderate reach. Through-spindle coolant delivery supports high-speed cutting operations in production environments.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the collet chuck. Ensure the mating spindle bore and shank are clean and free of chips or debris before seating the chuck. Verify coolant line connections at the spindle interface before resuming through-coolant operation.
