Accupro 777816 DA200 CAT40 Collet Chuck 3 in Projection

Product Description

The ACCUPRO 777816 is a Double Angle (DA200 series) collet chuck with a CAT40 taper shank, designed for CNC machining centers where tool-holding accuracy and coolant delivery are critical. It provides a 3-inch projection from the spindle face and holds a total indicator reading (TIR) of 0.0002 inches, making it suitable for precision milling, drilling, and reaming operations. The through-coolant design supports both through-spindle and DIN flange coolant delivery, directing fluid directly to the cutting edge. This chuck is installed by machinists and CNC setup technicians in production and job-shop environments.

This collet chuck is suited for CNC vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The DA200 collet series accommodates a range of tool shank diameters, with a minimum collet capacity of 3/64 inch and a maximum of 3/8 inch. The 3-inch projection makes it a practical choice for operations requiring clearance between the spindle nose and workpiece or fixture. It is balanced to 20,000 RPM, supporting high-speed machining strategies where vibration and runout control directly affect surface finish and tool life.

Key Features

• DA200 Double Angle collet system with CAT40 taper shank for secure, repeatable spindle engagement
• 0.0002-inch TIR for high-precision tool positioning and reduced runout
• 3-inch projection from spindle face for clearance in complex fixturing setups
• Through-coolant compatible via through-spindle and DIN flange coolant paths
• Balanced to 20,000 RPM for use in high-speed machining applications
• Accepts DA200 collets ranging from 3/64 inch to 3/8 inch shank diameter

Compatibility

Compatible with CAT40 spindle-interface machining centers using the DA200 Double Angle collet series. Collets sold separately and must conform to the DA200 standard.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machining center spindle before installing or removing the chuck. Ensure the CAT40 taper and spindle bore are clean and free of chips or coolant residue before seating the chuck. Torque the retention knob to the machining center manufacturer's specification using the appropriate spanner or retention-knob wrench.
