Kennametal 1605103 Hydraulic Chuck CAT40 0.5 in Bore

Product Description

The KENNAMETAL 1605103 is a hydraulic tool chuck designed for precision CNC machining operations. It features a CAT40 taper shank for direct spindle mounting and accepts a 0.5 inch (12.70 mm) bore diameter. The chuck delivers a 3.75 inch (95.25 mm) projection and a 1.25 inch (31.50 mm) nose diameter, keeping the cutting tool close to the spindle centerline while maintaining rigidity. It is rated to 15,000 RPM and includes through-coolant capability, making it suitable for high-speed drilling, reaming, and milling where coolant delivery at the tool tip is required. This type of toolholder is installed and serviced by CNC machinists and toolroom technicians.

This hydraulic chuck is suited for use in CNC machining centers equipped with CAT40 spindle interfaces. It is appropriate for both roughing and finishing operations where vibration damping and precise tool runout control are critical. The through-coolant feature supports applications involving deep-hole drilling or extended flute cutters where flood coolant alone is insufficient. It is commonly installed in production and job-shop environments running ferrous and non-ferrous materials at moderate to high spindle speeds.

Key Features

• CAT40 taper shank for direct compatibility with CAT40 spindle interfaces
• 0.5 inch (12.70 mm) bore diameter accepts standard half-inch shank tooling
• 95.25 mm (3.75 inch) projection for reach into deep features or fixtures
• Rated to 15,000 RPM for high-speed machining applications
• Through-coolant design delivers coolant directly to the cutting edge
• 1.25 inch (31.50 mm) nose diameter with 1.42 inch clamping depth for secure tool engagement

Compatibility

Designed for use with CAT40 spindle-equipped CNC machining centers. Accepts tooling with a 0.5 inch straight shank within the specified clamping depth of 1.42 inches.

Installation Notes

Installation and removal should be performed by a qualified CNC machinist or toolroom technician using a proper CAT40 toolholder tightening fixture and torque wrench. Power down and lock out the spindle drive before changing toolholders. Verify through-coolant port alignment with the machine spindle coolant supply before operation. Inspect the taper and bore for debris or damage prior to each installation to maintain runout accuracy.
