Kennametal 1605106 Hydraulic Chuck CAT40 1 Inch Bore

Product Description

The KENNAMETAL 1605106 is a hydraulic tool chuck with a CAT40 taper shank, designed for precision toolholding in CNC machining centers. The chuck grips cutting tools through hydraulic clamping pressure, providing high concentricity and vibration damping compared to conventional collet or set-screw holders. Key specs include a 1.000 inch (25.40 mm) bore diameter, 4.625 inch (117.48 mm) projection, and a maximum balanced speed of 15,000 RPM. Through-coolant capability delivers cutting fluid directly to the tool tip. This holder is installed and serviced by CNC setup technicians and toolroom machinists.

The 1605106 is suited for high-speed milling, drilling, and reaming operations on CAT40-spindle machining centers in both production and job-shop environments. The hydraulic clamping mechanism makes it appropriate for finish-critical operations where runout must be minimized. The 15,000 RPM rating supports high-speed machining strategies. Through-coolant support suits deep-cavity and long-reach applications where flood coolant is insufficient. This chuck is used in aerospace, automotive, die-mold, and general metalworking applications.

Key Features

• CAT40 taper shank for direct spindle mounting on standard CAT40 machining centers
• 1.000 inch (25.40 mm) bore diameter with 1.810 inch clamping depth for secure tool retention
• Hydraulic clamping delivers high concentricity and vibration damping for finish-critical cuts
• Balanced to 15,000 RPM for high-speed machining compatibility
• Through-coolant design channels cutting fluid to the tool tip
• 1.960 inch (49.78 mm) nose diameter and 7.317 inch overall length suit a range of workpiece setups

Compatibility

Designed as a direct-mount hydraulic toolholder for CAT40-spindle CNC machining centers. Compatible with cylindrical-shank cutting tools with a 1.000 inch shank diameter.

Installation Notes

CAT40 toolholders must be installed and torqued using the machining center spindle and the appropriate drawbar retention system per the machine tool manufacturer specifications. Power down and lock out the machining center spindle before handling or changing toolholders. Through-coolant fittings must be verified for proper sealing before operation to prevent coolant bypass. Tool clamping pressure should be set and verified per the hydraulic chuck manufacturer service guidelines before running the spindle.
