When precision is non-negotiable in CNC machining, you need a collet you can trust. The Omega ER50 Collet Standard Precision is engineered for reliable, round-tool clamping in ER50 collet chucks, delivering consistently tight grip with an impressively low run-out of 10 microns.

Why this matters: a 10 micron run-out translates to true concentric cutting, smoother finishes, and longer tool life since the tool remains aligned with the spindle across passes. This ER50 collet is designed for general-purpose machining where repeatable, dependable holding is essential, helping you achieve tighter tolerances without sacrificing productivity.

• Rigid, repeatable clamping — stable engagement across the cutting diameter to minimize tool deflection during heavy feeds
• ER50 chuck compatibility — precisely molded to seat and hold tools securely in standard ER50 systems
• 10 micron run-out — superior concentricity that enhances surface finish and part accuracy
• Versatile for common tooling — ideal for end mills, drills, and other round-shank tooling used in milling, drilling, and boring
• Low-maintenance performance — designed for easy cleaning and long-term reliability in busy shops

Applications and workflow: This collet shines in scenarios where consistent grip and minimal run-out directly impact part quality—think precision pocketing, slotting, and profiling with small-diameter end mills, as well as accurate drilling operations in aluminum, steel, and alloy parts. It’s an excellent fit for workshops that demand repeatable setups, quick tool changes, and reliable performance across multiple jobs.

Usage tips: keep the clamping surface free of chips and debris, verify the tool shank is within the intended range before clamping, and inspect the collet for scoring or wear during routine maintenance. Store the collet in a dry, clean environment to preserve its precision over time.

What you get: a standard precision ER50 collet designed for round tooling in ER50 chucks. The listing title notes 26mm - 24mm dimensions, reflecting the model’s size specification.
