Techniks 23659 Sbl Collet Chuck CAT40 8 in Projection

Product Description

The TECHNIKS 23659 is an SBL collet chuck with a CAT40 taper shank designed for CNC machining centers and milling applications. It accepts SBL6 series collets with a capacity range of 3/32 inch minimum to 1/4 inch maximum, making it well suited for small-diameter end mills, drills, and reamers. The chuck delivers an 8-inch projection from gauge line, with an overall length of 10.68 inches. At 1 pound, it adds minimal weight to the spindle assembly. Licensed machinists and CNC setup technicians are the primary installers of this toolholder.

This collet chuck is intended for use in CAT40-spindle machining centers in production and job shop environments. The 8-inch projection provides extended reach for deep-cavity milling, tall-fixture work, and applications where standard-projection toolholders cannot clear the workpiece or fixture. The SBL6 collet series supports a range of small-shank cutting tools commonly used in finish milling and precision drilling operations.

Key Features

• CAT40 taper shank for direct spindle mounting on CAT40 machining centers
• SBL6 collet series with 3/32 inch to 1/4 inch clamping capacity
• 8-inch projection for extended reach into deep cavities or tall fixtures
• 10.68 inch overall length for consistent gage-line reference
• No through-coolant configuration keeps setup straightforward for dry or flood-coolant applications

Compatibility

Designed for use with SBL6 series collets on CAT40 taper spindle machining centers. Accepts cutting tool shanks ranging from 3/32 inch to 1/4 inch diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC setup technician with the machine powered off and the spindle fully stopped. Use the appropriate CAT40 retention knob torqued per the machine tool builder specifications. Inspect the taper bore and shank for chips or contamination before seating the toolholder. Verify collet seating and runout with a dial indicator before resuming production cuts.
