Parlec ER25-0354 ER25 Collet 0.3543 Inch 9mm

Product Description

The PARLEC ER25-0354 is an ER25 series collet designed for precision workholding in CNC machining and milling applications. With a nominal collet size of 9.00 mm (0.3543 inches) and a minimum collet capacity of 8.0 mm (0.315 inches), this collet secures round shanked tooling with consistent clamping force. The overall length is 1.338 inches, fitting standard ER25 collet chucks used across a wide range of machining centers and manual mills. Installation and tool changes are performed by machinists and CNC operators as part of routine setup.

The ER25-0354 is suited for production and job-shop environments where ER25 toolholding systems are the standard. It accommodates cutting tools, drill bits, and end mills with shanks in the ER25 capacity range. The collet is appropriate for both horizontal and vertical machining center setups requiring repeatable tool runout and secure clamping across light to moderate cutting loads.

Key Features

• ER25 collet series for broad compatibility with standard ER25 chucks
• 9.00 mm nominal collet size with 0.3543 inch decimal equivalent
• Minimum collet capacity of 8.0 mm (0.315 inches) for reduced-shank tooling
• Overall length of 1.338 inches fits standard ER25 chuck pockets
• Lightweight at 1 pound for easy handling during tool changes

Compatibility

Designed as a direct-fit replacement collet for standard ER25 collet chucks used in CNC machining centers and manual milling applications.

Installation Notes

ER collets are installed and removed by machinists using an appropriate ER25 collet nut and spanner wrench. Always ensure the spindle is fully stopped and the machine is in a safe, locked-out state before performing tool changes. Inspect the collet bore and chuck taper for debris or damage before seating the collet. Do not exceed the collet capacity range to avoid tool slippage or collet damage.
