Techniks 22403 CAT40 Drill Chuck 1/32 to 1/2 Inch

Product Description

The TECHNIKS 22403 is a CAT40 integrated SPU drill chuck designed for use in CNC machining centers and milling applications. It accepts drill shank diameters from 1/32 inch to 1/2 inch, covering a wide range of twist drills and cutting tools commonly used in metal fabrication and general machining. The integrated SPU design combines the chuck body and arbor into a single unit, reducing runout and improving rigidity compared to two-piece assemblies. This chuck is installed and serviced by machinists and toolroom technicians maintaining CNC tooling inventories.

The TECHNIKS 22403 is suited for use in production machining environments where a CAT40 spindle taper is standard. It is appropriate for vertical machining centers, drill presses with CAT40 spindles, and similar equipment requiring reliable, repeatable tool holding across varied drill diameters. The 1/32 inch to 1/2 inch capacity range makes it a versatile toolholder for shops running mixed drilling operations without frequent chuck changes.

Key Features

• CAT40 taper shank for direct spindle mounting on compatible machining centers
• Integrated SPU construction eliminates separate arbor for improved concentricity
• Capacity range of 1/32 inch to 1/2 inch accommodates common drill shank sizes
• Single-piece design reduces tool assembly time during setup

Compatibility

Designed as an OEM-style toolholder replacement for CNC machining centers and drill applications using a CAT40 spindle taper interface.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CAT40 toolholder procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the chuck. Use the appropriate CAT40 retention knob and follow the machine manufacturer torque guidelines for drawbar engagement. Inspect the taper seat and chuck body for contamination or damage before each installation.
