Description
Introducing the Omega ER20 Collet Standard Precision—a dependable, high-concentricity clamping solution for your ER20 collet chuck. Engineered for precision machining, this collet delivers tight tolerance with a 10 micron run-out, helping you achieve cleaner cuts, smoother finishes, and longer tool life in every project.
- 10 micron run-out ensures exceptional concentricity between the tool and workpiece, reducing run-out chatter and improving hole accuracy and surface finish.
- ER20 standard precision design provides reliable, repeatable clamping in common ER20 collet chucks for a wide range of small-diameter tooling and workpieces.
- Small-diameter range compatibility optimized for precision tasks in the 2.0–2.5 mm range, making it ideal for micro-milling, fine drilling, and delicate engraving applications.
- Durable construction forged from hardened steel to withstand repeated clamping and high-speed machining without loss of accuracy.
- Versatile for general-purpose machining suited to CNC milling, manual milling, and other operations where tight tolerance and repeatable performance matter.
In practice, the Omega ER20 Collet Standard Precision shines in micro-machining environments—where tool deflection and run-out can compromise tolerances. Use it with an ER20 chuck to achieve repeatable results across jobs, from precise pocketing and finishing passes to consistent drill diameters and clean slotting. The 10 micron run-out level helps you push your small-diameter tooling to its full potential, delivering standout precision even at higher spindle speeds.
Ideal for: hobbyists, small machine shops, and professionals working on precision milling, micro-drilling, engraving, and other small-diameter applications that demand reliable, repeatable clamping and minimal run-out.
Pro tips to maximize performance: keep the collet clean and free of debris, pair it with compatible ER20 chucks designed for tight tolerances, and ensure your tooling is within the specified 2.0–2.5 mm range for optimal grip and accuracy.
