Kennametal 1949905 ER16 Collet 5/32 Inch 0.1563 Bore

Product Description

The KENNAMETAL 1949905 is an ER16 series collet with a 0.1563 inch (5/32 inch) bore diameter, designed for use in ER16-compatible collet chucks on CNC machining centers, milling machines, and drill presses. It delivers a maximum total indicator runout (TIR) of 0.0152 mm (0.0006 inch), providing the precision necessary for accurate tool holding in tight-tolerance operations. With an overall length of 27.51 mm and an overall diameter of 16.99 mm, this collet fits standard ER16 chuck bodies without modification. Machinists and tool-room technicians rely on this collet for consistent clamping force and minimal runout across high-speed cutting applications.

This collet is suited for light to medium-duty machining operations where a 5/32 inch shank cutting tool must be held securely. Typical applications include end milling, reaming, and drilling in production and job-shop environments. The ER16 series is widely used in both manual and CNC setups where compact tooling and precise runout control are required. It is appropriate for use on vertical machining centers, bench mills, and similar equipment equipped with ER16 collet chucks.

Key Features

• ER16 series collet compatible with standard ER16 collet chucks

• Overall diameter of 16.99 mm matching standard ER16 chuck taper geometry

Compatibility

Designed for use in standard ER16 collet chucks accepting 0.1563 inch bore collets. Verify chuck taper and clamping nut specifications against your equipment before installation.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Before changing collets, power down and lock out the spindle drive per OSHA lockout/tagout procedures. Seat the collet fully into the ER16 collet chuck before threading the clamping nut, and use a calibrated collet chuck wrench to achieve proper clamping torque as specified by the chuck manufacturer. Inspect the collet seating surface and chuck taper for burrs or debris before each use to maintain runout performance.
