Techniks 23658 Sbl Collet Chuck CAT40 6 Inch Projection

Product Description

The TECHNIKS 23658 is an SBL collet chuck with a CAT40 taper shank, designed for precision workholding in CNC milling and machining centers. It features a 6-inch projection and through-coolant capability, making it well suited for deep-reach applications where coolant delivery directly to the cutting tool is required. The chuck accepts SBL6 series collets with a clamping range of 3/32 inch to 1/4 inch, covering small-diameter end mills, drills, and reamers. The overall length is 8.68 inches. This tool holder is installed and serviced by CNC machinists and toolroom technicians.

This collet chuck is used in CAT40-spindle machining centers running small-diameter cutting tools where extended reach and coolant-through performance are priorities. The 6-inch projection allows access to deep features or tall workpieces without the need for extended-length cutting tools. Through-coolant support helps with chip evacuation and tool life in demanding materials. Typical applications include production milling, aerospace fixturing, and die-mold work where precise, repeatable tool runout is critical.

Key Features

• CAT40 taper shank for direct mounting in standard CAT40 CNC spindles
• SBL6 collet series with a clamping range of 3/32 inch to 1/4 inch
• 6-inch projection for extended reach into deep workpiece features
• Through-coolant design routes fluid directly to the cutting edge
• Overall length of 8.68 inches for consistent gage-line reference during setup

Compatibility

Designed for use with CAT40-taper CNC machining centers and accepts SBL6 series collets. Collet capacity range is 3/32 inch minimum to 1/4 inch maximum.

Installation Notes

Installation is performed by a CNC machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the tool holder. Use a properly rated CAT40 pull stud and torque the retention knob per the machine tool manufacturer specifications. Inspect collet seats and taper shanks for damage or contamination before assembly, as debris will affect runout and clamping force.
