Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 6mm - 5mm

Omega Products ER25 Collet Standard Precision delivers dependable, repeatable clamping for everyday machining tasks. Built to fit standard ER25 collet chucks, this set keeps your tooling aligned and your workpiece true, helping you achieve cleaner cuts and longer tool life. With a standout 10 µm (0.01 mm) run-out, it’s a practical choice for general purpose milling, drilling, and precision work where concentricity matters.

What makes this ER25 collet stand out

• 10 µm run-out – tight concentricity translates to more accurate toolpaths, better surface finishes, and reduced workpiece distortion on every pass.
• ER25 compatibility – engineered to drop into standard ER25 collet chucks, delivering reliable clamping without the guesswork or fuss of improvised setups.
• 5–6 mm tooling range focus – optimized for common small-diameter tools, making it a practical choice for micro-machining and detailed work.
• Versatile, general-purpose performance – ideal for a wide range of machining tasks, from light milling to precise drilling, where consistent run-out is crucial.
• Durable, repeatable grip – designed to maintain clamping force over many cycles, so you spend less time adjusting and more time cutting.

How this ER25 collet helps you work smarter

• Improve part quality – true run-out minimizes tool deflection and eccentricity, resulting in straighter holes, cleaner finishes, and tighter tolerances.
• Reduce setup time – fast, confident locking into an ER25 chuck means fewer adjustments between tools and fewer scrap parts.
• Support for precision workflows – especially useful in jobs where multiple passes are needed or when producing repeatable batches of parts.

Best use scenarios

• Milling small pockets and features in aluminum, brass, and mild steels with consistent results.
• Drilling precise holes where concentricity between the drill and the workpiece is critical.
• Engraving or finishing operations that require stable, low-run-out grip on the cutting tool.

Simple care and usage tips

• Keep the collet area clean and free of chips to preserve run-out accuracy.
• Use the correct ER25 collet size for your tool shank and avoid over-tightening—torque to the chuck’s recommended spec.
• Inspect the collet edges for wear or nicks; replace if signs of damage appear to maintain precision.

With the Omega ER25 Collet Standard Precision, you’re choosing a focused, reliable solution for accurate, repeatable machining. It’s built for real-world shop use—where precision meets practicality—and designed to keep your workflows efficient from setup to finish.
