Omega Products ER20 Collet Standard Precision - 10 Micron Run-Out - 14mm - 13.8mm

When precision is non‑negotiable, reach for the Omega ER20 Collet Standard Precision. Engineered to fit a standard ER20 collet chuck, this collet keeps tooling centered with exceptional concentricity and a tight 10 micron run-out, delivering reliable accuracy across routine machining tasks and delicate finishes.

Key benefits that matter in real work

• 10 micron run-out — minimizes eccentricity between tool shank and holder, reducing vibration, chatter, and tool wear for cleaner cuts and better surface finishes.
• ER20 compatibility — specifically designed to clamp round tool shanks in an ER20 collet chuck, ensuring straightforward integration into existing setups with minimal fuss.
• Concentric, repeatable clamping — precision-ground seating surfaces maintain consistent grip through many cycles, supporting repeatable results job after job.
• Durable build — rugged steel construction and hardened interfaces stand up to daily shop use, resisting deformation and maintaining accuracy over time.
• Size specification — 14mm and 13.8mm range (as listed in the product title), designed to align with common small-tooling applications and ER20 chuck setups.

Ideal applications

Perfect for CNC milling, drilling, and engraving where small-diameter end mills, carbide tools, or drill bits need secure, precise holding. Whether you’re refining aluminum components, working brass hardware, or processing steels, the 10 micron run-out helps you achieve tighter tolerances and more consistent tool paths across passes.

How this collet solves common problems

• Eliminates excessive run-out that leads to poor hole quality and irregular milling finishes.
• Reduces tool deflection and chatter on delicate operations, extending tool life.
• Provides reliable, repeatable seating so setups reproduce to the same reference point after tool changes.

Practical tips for best results

• Ensure the tool shank and collet seating surface are clean before insertion to maximize concentric seating.
• Avoid over-tightening beyond recommended torque on the ER20 chuck to preserve collet integrity.
• Match cutting fluid and feed rates to the material to optimize the benefits of the low run-out performance.
• Pair with sharp, correctly sized tools to fully leverage the collet’s precision holding capability.

What you gain with Omega ER20 Collet Standard Precision

Consistent grip, minimized run-out, and reliable repeatability across your machining workflow. This is a practical upgrade for shops and hobbyists who demand precise tool retention without the complexity of more elaborate holding systems.
