Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 16.5mm - 16.3mm

When precision matters in metalworking, the Omega ER25 Collet Standard Precision delivers reliable, repeatable clamping for round stock in an ER25 collet chuck. Designed for general-purpose machining, this collet keeps run-out tight at 10 μm, so your cuts stay true and your tolerances hold through repeat cycles.

Key benefits that matter in the workshop

• 10 μm run-out tolerance for superior concentricity, reducing taper, eccentricity, and finishing imperfections.
• ER25 compatibility pairs with standard ER25 collet chucks, simplifying integration into existing setups.
• Clamping range around 16.3–16.5 mm, aligning with common workpiece sizes and the specification in the product title.
• Robust construction built to withstand repeated clamping and unclamping during daily machining tasks.
• Segmented jaw design distributes clamping force evenly for a consistent grip on round stock.

Whether you’re milling pockets, drilling holes, or performing light reaming, this ER25 collet helps you maintain tight tolerances and reduce setup time. It’s an ideal choice for machinists, shop technicians, and hobbyists who demand dependable performance from their tooling.

Why this ER25 collet stands out

Precision without compromise is achievable when your tooling minimizes run-out from the first clamp. The Omega ER25 Collet Standard Precision focuses on reliable concentricity and repeatable results, so you can trust every operation—from roughing to finishing. By delivering a consistent grip on round stock, it helps you achieve cleaner cuts, smoother finishes, and more predictable outcomes in a wide range of metalworking applications.

Practical tips for optimal performance

• Keep the collet and chuck interfaces clean; remove chips and coolant before reassembly to preserve accuracy.
• Use the proper tightening sequence and avoid over-torquing to prevent distortion of the clamping surfaces.
• Pair with sharp, well-maintained tooling to maximize the 10 μm run-out advantage and extend tool life.
