Lyndex-nikken SK6-1/4A SK6 Slim Chuck Collet 0.25 Inch

Product Description

The LYNDEX-NIKKEN SK6-1/4A is a single angle collet designed for use in SK6 slim chuck toolholding systems on CNC machining centers and milling machines. With a collet size of 0.25 inches, an overall length of 0.969 inches, and a maximum body diameter of 0.394 inches, this collet delivers precise, concentric clamping of cutting tools in compact, tight-clearance applications. It is installed by machinists and CNC setup technicians who require consistent tool runout performance in high-speed machining environments.

The SK6-1/4A fits SK6 slim chuck toolholders used in vertical and horizontal machining centers where reduced-diameter toolholding is required for deep-cavity milling, die and mold work, or close-wall machining. The slim chuck profile allows access to workpiece features that standard-diameter toolholders cannot reach. This collet is suited for light to medium-duty milling, drilling, and finishing operations using 0.25-inch shank tooling.

Installation Notes

SK6 slim chuck collets are installed and removed by qualified machinists or CNC toolroom technicians using the appropriate collet nut wrench and holder fixture. Always power down and lock out the machine spindle before changing collets. Inspect the collet bore and holder taper for chips, debris, or wear before seating the collet. Do not exceed the toolholder manufacturer's specified torque range when tightening the collet nut.
