Techniks 23654 SBL6 CAT40 Collet Chuck 3 in Projection

Product Description

The TECHNIKS 23654 is an SBL6 series collet chuck with a CAT40 taper shank, designed for use in CNC machining centers that require precise, repeatable tool holding. It features a 3-inch projection from the gauge line and accepts SBL collets ranging from 3/32 inch to 1/4 inch in diameter. At 5.68 inches overall length and 1 pound, this chuck is built for light-tooling applications where clearance and reach matter. Machinists and CNC setup technicians working with small-diameter end mills, drills, or reamers will find this chuck a direct-fit solution for CAT40-spindle machines.

This collet chuck is suited for vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. The SBL6 collet series is commonly used in high-speed applications requiring close-tolerance tool concentricity. Typical installations include production milling, drilling, and light contouring operations where small-diameter tooling must be held securely. The 3-inch projection makes this chuck useful when machining around fixtures or workholding that limits access to the cutting zone. No through-coolant capability is present, so external coolant delivery is required for flood or mist applications.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle interfaces
• SBL6 collet series accepts tooling from 3/32 inch to 1/4 inch diameter
• 3-inch projection provides reach over fixtures and complex workholding setups
• 5.68-inch overall length for predictable tool-length offsets during setup
• Lightweight at 1 pound, reducing spindle load in high-cycle applications
• No through-coolant - compatible with external coolant delivery systems

Compatibility

Designed as an OEM-style replacement and standard tooling solution for CNC machining centers with CAT40 taper spindles using the SBL collet system.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the chuck. Use a calibrated torque wrench and the appropriate spanner wrench for the collet nut - never use impact tools on collet nuts. Verify tool runout with a dial test indicator after mounting to confirm concentricity before cutting.
