Kennametal 1105989 ER32 Collet 0.6300 Inch 16.00mm

Product Description

The KENNAMETAL 1105989 is an ER32 series collet designed for use in ER32-compatible collet chucks on CNC machining centers, milling machines, lathes, and toolholding systems. It holds tooling at a nominal collet size of 0.6300 inch (16.00mm) with a total indicated runout (TIR) of 0.0008 inch (0.0203mm), making it suitable for precision machining applications where concentricity and repeatability are critical. Machinists and toolroom technicians install this collet to secure end mills, drills, reamers, and other round-shank cutting tools.

This collet is intended for use in production and toolroom environments where ER32 collet chucks are the standard workholding interface. The ER32 series is one of the most widely used collet standards in CNC milling and drilling operations, fitting both vertical and horizontal machining centers. The 1105989 is sized for 16.00mm shank tooling and is appropriate for both roughing and finishing operations where low runout is required for tool life and surface finish.

Key Features

• ER32 collet series - compatible with standard ER32 collet chucks
• Nominal collet size of 0.6300 inch (16.00mm) for round-shank tooling
• Low TIR of 0.0008 inch (0.0203mm) for precise concentricity
• Overall assembly length of 40.01mm supports standard gage-line projections
• Lightweight at 0.25 pounds for easy handling during tool changes

Compatibility

Designed for use with standard ER32 collet chucks and toolholders conforming to the ER32 collet interface specification.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing collets. Ensure the collet, chuck bore, and clamping nut are free of chips and debris before seating the collet. Torque the collet nut using an appropriate ER collet wrench to the chuck manufacturer specifications - do not use makeshift tools that can damage the nut or collet flange.
