Kennametal 1605102 Hydraulic Chuck CAT40 3/8 in Through Coolant

Product Description

The KENNAMETAL 1605102 is a hydraulic tool chuck designed for precision CNC milling and machining applications. It features a CAT40 taper shank and accepts cutting tools with a 3/8 inch (9.53 mm) bore diameter. Hydraulic clamping delivers consistent, vibration-dampening grip on the tool shank, supporting tight tolerances and extended tool life. The chuck is rated to 15,000 RPM and includes through-coolant capability, directing cutting fluid directly to the tool tip for improved chip evacuation and thermal management. The nose diameter is 1-5/32 inches (29.72 mm) with a projection of 3-3/4 inches (95.25 mm).

This chuck is suited for high-speed machining centers running milling, drilling, or reaming operations where runout control and vibration reduction are critical. Through-coolant support makes it appropriate for deep-pocket milling and long-reach applications where flood coolant alone is insufficient. It is installed and serviced by CNC machinists and tooling technicians in production shops, job shops, and aerospace or automotive manufacturing environments.

Key Features

• CAT40 taper shank for standard CNC machining center spindle interface
• 3/8 inch (9.53 mm) tool bore with 1.22 inch clamping depth for secure hydraulic grip
• Rated to 15,000 RPM for high-speed machining operations
• Through-coolant design directs fluid to the cutting edge for improved thermal control and chip removal
• Overall length of 6.437 inches (163.50 mm) with 3-3/4 inch (95.25 mm) projection
• 1-5/32 inch (29.72 mm) nose diameter for clearance in tight workpiece geometries

Compatibility

Designed for use with CAT40 spindle-equipped CNC machining centers accepting hydraulic-style tool chucks with a 3/8 inch bore diameter and through-coolant capability.

Installation Notes

Installation and tool changes should be performed by a qualified CNC machinist or tooling technician with the machine powered down and spindle locked. Use the appropriate CAT40 pull-stud torque specification as defined by the machine tool builder before seating the chuck in the spindle. Do not exceed the rated 15,000 RPM without confirming the tool assembly has been dynamically balanced to an acceptable G-grade per ISO 1940 standards. Verify through-coolant connections and seals are intact before pressurizing the coolant circuit.
