Product Description

The PARLEC ER40-0281 is an ER40 series collet designed for use in ER40-compatible toolholders on CNC machining centers, milling machines, and drilling applications. It accepts workpieces and cutting tools up to 0.281 inches in diameter, with a minimum collet capacity of 0.242 inches, giving the tool a clamping range suited to a wide variety of standard shank tooling. The overall length is 1.811 inches. Machinists and toolroom technicians install this collet as part of a standard ER40 collet chuck system to secure end mills, drills, reamers, and similar tooling during cutting operations.

This collet is suited for general-purpose machining environments where ER40 toolholding systems are in use. It fits residential shop, production, and industrial CNC setups alike. The ER40 series is one of the most widely adopted collet standards in the industry, making this collet a common replacement and spare for shops running ER40 chucks on lathes, mills, and machining centers that require precise, repeatable toolholding at the 0.281-inch capacity range.
