Omega ER50 Collet — Standard Precision with 10 µm Run-Out
When your machining demands unwavering concentricity, the Omega ER50 Collet delivers. This standard precision collet is designed to slip into an ER50 collet chuck and hold round workpieces with exceptional steadiness, thanks to a tight 10 micron run-out. For everyday milling, drilling, and general-purpose machining, this collet keeps your tooling centered so you achieve cleaner cuts, tighter tolerances, and more repeatable results cycle after cycle.

Key advantages you’ll notice in real-world workflows:
- Precision you can feel — a 10 µm run-out minimizes tool deflection and workpiece run-out, leading to crisper edges and more accurate features on every pass.
- Reliable round-work clamping — engineered for round stock and round tooling, the ER50 standard collet delivers consistent grip without marring surfaces.
- Versatile, with broad compatibility — built to work with the widely adopted ER50 family of collet chucks, making it a practical choice for shops standardizing their toolholding setup.
- Durable, shop-ready construction — designed for repeated clamping cycles in busy production environments, maintaining performance through your day-to-day machining tasks.
- Effortless integration — drop this collet into your ER50 chuck and lock in repeatable accuracy across multiple jobs without the need for frequent recalibration.
Who benefits most from the Omega ER50 Collet? This standard precision option is ideal for machinists and shop environments where reliable, repeatable performance matters more than flashy features. It’s particularly well-suited for operations that require tight tolerances on round parts, such as precision milling runs, drilling operations where concentricity saves material, and general-purpose fixtures where consistent grip and minimal run-out translate to better surface finishes and longer tool life.
Why choose this ER50 collet over other toolholding options? The answer lies in the combination of stability and simplicity. The 10 µm run-out specification means less angular error during cutting, which reduces cutter wear and improves finish quality on each piece. Its standard design ensures straightforward installation into existing ER50 chucks, so you can scale up your fixtureing without a steep learning curve or costly retooling.
Practical tips to maximize performance:
- Before use, inspect the collet bore for any debris or nicks that could compromise concentricity. A clean bore helps maintain the 10 µm run-out spec in practice.
- Pair the ER50 collet with properly matched tooling and round stock to preserve grip integrity and minimize deflection during heavy cuts.
- Always torque to the manufacturer’s recommended clamping force for smooth seating and repeatable results across jobs.
- Schedule regular maintenance checks on your toolholding system to detect wear early and keep run-out within specification.
Specifications at a glance (based on standard ER50 collet design and the stated precision):
- Collet type: ER50
- Run-out: 10 microns
