The Omega ER50 Collet Standard Precision is built for reliable, trouble-free toolholding in high-precision machining. Designed to pair with a standard ER50 collet chuck, this collet delivers consistent clamping force and true concentricity for round tooling across a wide range of milling and drilling tasks.

With a tight 10 micron run-out specification, you’ll notice noticeably improved run-out control, which translates to smoother toolpaths, cleaner finishes, and longer tool life—even at higher feed rates and speeds. This level of precision is particularly beneficial for precision milling, engraving, pocketing, and delicate drilling where every micron matters.

Key dimensions you’ll rely on: a 36mm body diameter combined with a 35.8mm seating/bore interface, designed to lock securely into standard ER50 collet chucks and maintain alignment through repeated clamping cycles. The geometry is crafted to minimize run-out at the clamping point, ensuring repeatable results from job to job.

Why choose this ER50 collet in your shop?

• Precision you can trust: 10 micron run-out supports tight tolerances and high-accuracy applications.
• Designed for standard ER50 chucks: seamless compatibility with widely used toolholding systems.
• Consistent grip: robust clamping action holds round tools securely, reducing chatter and deflection during heavy milling.
• Versatile for general machining: ideal for everyday tasks—from rough milling to fine finishing—without sacrificing accuracy.

This collet is a practical upgrade for machinists who demand dependable performance from their toolholding. It’s well-suited for shops that run high-precision end mills, carbide tools, and other round tooling where concentricity directly affects surface quality and dimensional accuracy.
