Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 14mm - 13mm

Introducing the Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 14mm - 13mm: a dependable, high-precision solution for toolholding in ER40 collet chucks. Built for consistency and repeatability, this collet keeps your cutting tools centered and your workpiece true, every time you run the machine.

• 10 micron run-out ensures minimal deviation between the tool shank and the collet bore, delivering smoother cuts, cleaner finishes, and tighter tolerances on every pass.
• 13–14 mm clamping range is specifically suited for tools within this diameter, making it ideal for standard end mills, drills, and similar round shanks that fall in that size window.
• ER40 compatibility means seamless integration with standard ER40 collet chucks used on a wide range of milling machines and CNC setups, promoting quick setup and reliable gripping.
• Robust, precision-ground construction leverages hardened steel and a segmented design to provide uniform grip across the entire shank, reducing runout-caused chatter and tool deflection.
• Repeatable performance for general machining—not just a one-off grab—making it a practical choice for shops and hobbyists who value consistency across multiple parts and batches.

Who benefits most: machinists, fabricators, and model-makers who rely on tight run-out and dependable collet performance for milling, drilling, and light reaming tasks. If your work involves 13–14 mm tool shanks and you want minimized run-out to improve hole sizes, surface finish, and overall accuracy, this ER40 collet is built to deliver.

Practical tips for best results: ensure tools are clean and free of burrs before clamping, insert the tool fully for maximum grip, and snug the chuck according to your machine’s torque recommendations. Regularly inspect the collet for wear or nicks—any damage can increase run-out and affect accuracy. For repeatable outcomes, keep a consistent clamping sequence and verify tool alignment after tool changes.
