Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 10mm - 9mm

Omega's ER25 Collet – Standard Precision is engineered for reliable, repeatable clamping in ER25 collet chucks. Designed for general-purpose machining, it delivers an exceptionally tight run-out specification—10 microns—so tools and workpieces stay concentric through every pass, yielding cleaner holes, tighter tolerances, and longer tool life.

• 10 µm run-out: near-perfect concentric gripping that minimizes tool deflection during milling, drilling, and reaming.
• Standard precision for ER25 collets: a dependable balance of accuracy and value for everyday metalworking and fabrication tasks.
• Uniform clamping surface with a segmented design to ensure even contact along the tool shank, boosting rigidity and reducing run-out across the workpiece.
• Repeatable performance across multiple setups, helping you achieve consistent results from job to job.
• Durable, shop-friendly construction built to withstand daily use in CNC, milling, and precision machining environments. Regular cleaning and inspection keep performance at its peak.

Who it's for: both hobbyists and professionals performing precision milling, drilling, or engraving who rely on tight run-out and dependable clamping in ER25 collet chucks. Because this is a standard ER25 collet, it integrates smoothly with a wide range of tooling and chucks to fit common workshop workflows and toolholding setups.

Practical tips for best results: pair this collet with accurately prepared tooling and clean shanks, ensure the workpiece surface is deburred and free of chips before clamping, and re-check run-out after aggressive cutting to confirm continued accuracy.
