Omega Products ER20 Collet Standard Precision - 10 Micron Run-Out - 15mm - 14.8mm

Meet the Omega ER20 Collet, Standard Precision — a reliable, high-precision clamping solution designed for ER20 collet chucks. Built to keep tooling concentric and true, this collet delivers a dependable 10 micron run-out (0.01 mm), meaning smaller tolerances, cleaner finishes, and fewer chatter-induced blemishes on every pass.

• Ultra-tight run-out: 10 µm (0.01 mm) ensures precise tool engagement and consistent diameter during cutting, drilling, and milling.
• ER20 compatibility: specifically engineered to fit standard ER20 collet chucks for smooth, repeatable tool changes.
• Accurate sizing for compact tools: optimized with a 15 mm / 14.8 mm range to securely clamp round tools within the ER20 family, enhancing rigidity where it matters most.
• General-purpose machining: ideal for a wide range of applications—from delicate engraving and fine milling to quick-turn prototyping and hobby shop projects.
• Consistent performance: engineered to maintain concentricity over repeated cycles, helping you achieve repeatable results across sessions.

Why choose this ER20 collet for your workflow

When precision matters, the difference is in the grip. A 10 micron run-out minimizes tool deflection and eccentricity, which translates to:

• Sharper tool paths with tighter tolerances
• Cleaner chip removal and better surface finish
• Longer tool life due to reduced concentricity errors

Who benefits most

Ideal for CNC operators, model-makers, and metalworkers who demand dependable accuracy from their ER20 collet systems. If you’re refining small-diameter end mills, micro-drills, or precision engraving tools, this collet helps you keep your parts within spec and your workflow efficient.

Practical usage tips

• Inspect tool shanks for cleanliness before clamping to maximize the 10 µm run-out performance.
• Ensure the ER20 chuck and collet seat are clean and free of debris to maintain concentric engagement.
• When installing, lightly seat the tool and then apply a controlled tightening sequence to avoid introducing run-out.
• For repeat jobs, keep a small set of go-to collets organized to minimize setup time and preserve machining consistency.

With the Omega name backing robust, repeatable precision and a compact, dependable design, this ER20 Collet Standard Precision is built for machinists who value accuracy as much as efficiency. Add it to your toolkit and experience tighter tolerances, smoother finishes, and one-step reliability in every project.
