Techniks 154750 Hydraulic Tool Chuck Taper Shank

Product Description

The TECHNIKS 154750 is a hydraulic tool chuck with a taper shank designed for precision toolholding in CNC machining applications. It features a 38 mm (1.5000 inch) nose diameter and accepts a 3/4 inch hole diameter, making it suitable for holding straight-shank cutting tools with consistent radial clamping force. The taper shank interface provides rigid, repeatable positioning in compatible spindle tapers. Through-coolant capability allows cutting fluid to pass directly through the chuck body to the tool tip, supporting high-speed and deep-cavity machining operations. Weighing 2.7 pounds, this chuck is installed by CNC machinists and toolroom technicians.

This hydraulic chuck is intended for use in CNC machining centers and mill spindles where accurate tool runout and vibration damping are required. The through-coolant feature makes it well suited for drilling, reaming, and finish milling operations where coolant delivery at the cutting edge improves tool life and surface finish. The 3/4 inch shank diameter accommodates standard straight-shank tooling commonly used in production and job-shop environments.

Key Features

• 38 mm (1.5000 inch) nose diameter for compatibility with standard toolholder setups
• 3/4 inch hole diameter accepts straight-shank cutting tools
• Taper shank interface provides rigid, repeatable spindle engagement
• Through-coolant design delivers fluid directly to the cutting zone
• Hydraulic clamping mechanism distributes uniform radial force for low runout

Compatibility

Designed as an OEM-style hydraulic toolholder replacement for CNC machining centers and mill spindles accepting taper shank chucks with a 3/4 inch bore and 38 mm nose diameter.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before removing or installing any toolholder. Ensure the spindle taper and chuck taper are clean and free of chips or coolant residue before seating. Follow the machine tool manufacturer torque and drawbar specifications for securing the taper shank.
