Lyndex-nikken SK16-1/2A Slim Chuck Collet 0.5 Inch SK16

Product Description

The LYNDEX-NIKKEN SK16-1/2A is a single angle slim chuck collet designed for precision CNC machining applications. Built to the SK16 collet standard, this collet accepts a 0.5 inch tool shank and delivers a total indicator runout (TIR) of 0.0002 inches, making it well-suited for high-accuracy milling, drilling, and light finish work. The body diameter measures 0.94 inches with an overall length of 1.77 inches. Machinists and CNC setup technicians install this collet into compatible SK16 slim chuck tool holders to secure cutting tools with consistent concentricity and minimal vibration at elevated spindle speeds.

This collet is intended for use in SK16-series slim chuck tool holders mounted on CNC machining centers. The slim chuck profile allows access in tight-clearance workpiece areas where standard chuck bodies would interfere. It is commonly used in production and job-shop environments running vertical or horizontal machining centers where high spindle speeds and close-tolerance finishes are required. The 0.0002 inch TIR specification supports repeatable tool positioning across multiple setups.

Key Features

• SK16 collet series for use with SK16 slim chuck tool holders
• 0.5 inch bore diameter accepts standard half-inch shank cutting tools
• 0.0002 inch TIR for high-precision concentricity
• 0.94 inch maximum body diameter suits slim-profile holder designs
• 1.77 inch overall length provides compact tool assembly stack height

Compatibility

Designed as an OEM-style replacement or production collet for SK16-series slim chuck tool holder systems. Compatible holder and collet series must match - confirm SK16 designation on the tool holder before installation.

Installation Notes

Installation is performed by CNC toolroom technicians or setup machinists. Before installing or removing this collet, power down and lock out the machine spindle per OSHA lockout/tagout procedures. Use the correct spanner wrench for the SK16 holder to achieve proper collet seating - do not use pipe wrenches or improvised tools that may damage the collet taper. Inspect the collet bore and holder taper for chips, burrs, or contamination before assembly, as debris will directly impact runout and tool life.
