Kennametal 2508153 Hydraulic Chuck CAT40 0.5 Inch

Product Description

The KENNAMETAL 2508153 is a hydraulic tool chuck designed for CAT40 taper shank spindles. It uses hydraulic clamping force to grip cutting tools with a 0.5 inch (12.70 mm) bore diameter, delivering consistent radial accuracy and vibration damping during milling, drilling, and reaming operations. With a projection of 169.93 mm and an overall length of 238.18 mm, this chuck suits applications where extended reach is required. It is balanced to 15,000 RPM and supports through-coolant delivery, making it compatible with high-speed machining centers used in production and job shop environments. The unit weighs 3.77 pounds.

This chuck is intended for use on CAT40-spindle CNC machining centers in both horizontal and vertical configurations. The 36.07 mm clamping depth and 19.56 mm nose diameter support secure tool engagement across a range of shank diameters within the 0.5 inch bore. Through-coolant capability allows coolant to be directed to the cutting zone, extending tool life and improving chip evacuation in deep-pocket or high-feed operations. It is suited to production environments where runout control and balanced high-speed performance are priorities.

Compatibility

Designed for use with CAT40-spindle CNC machining centers requiring a 0.5 inch bore hydraulic chuck with through-coolant capability.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machining center spindle before mounting or removing the chuck. Ensure the CAT40 taper and spindle bore are clean and free of chips or coolant residue before seating the chuck. Follow the machining center manufacturer guidelines for drawbar torque and tool change procedures.
