Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 12mm - 11mm

The Omega ER25 Collet Standard Precision is built for dependable, repeatable toolholding in your ER25 collet chuck. Designed for general purpose machining, these collets deliver true concentricity and consistent clamping every time you clamp a round tool or workpiece.

Why this ER25 Collet stands out

• 10 micron run-out for superior accuracy and cleaner finishes across milling, drilling, and light slotting tasks.
• Standard precision reliability—crafted to hold round tools securely in ER25 chucks with minimal run-out variation.
• 12mm - 11mm sizing optimized for a common range of shanks and workpieces, facilitating quick, repeatable setups.
• Durable steel construction built to withstand everyday shop conditions and maintain grip over many cycles.
• Easy integration fits with standard ER25 collet chucks, enabling straightforward swaps and fast changeovers in busy workflows.

Ideal uses and scenarios

Perfect for hobbyists and professional shops alike, the Omega ER25 collet shines in scenarios where holding round stock with minimal run-out matters most. Use it for:

• Precision milling of small-diameter end mills, drills, and dedicated tooling
• Prototype and small-batch production where consistent tool alignment impacts dimensional accuracy
• General purpose machining on aluminum, brass, and steel where clean surfaces and tight tolerances are required

Performance you can trust

Compared to improvised holding methods, this ER25 collet provides repeatable grip and concentricity, helping reduce tool wear, improve surface finish, and minimize setup time. When you need reliable, predictable results from your ER25 collet chuck, this standard precision option is a practical, value-driven choice.

Care and best practices

• Keep the collet and tool shanks clean and free of debris to maintain optimal grip.
• Lightly lubricate moving parts and ensure the chuck is properly tightened to spec before every use.
• Store in a dry environment to prevent corrosion and ensure long-term performance.

Enhance your machining setups with the Omega ER25 Collet Standard Precision—where precision, reliability, and ease of use come together for consistent, high-quality results.
