Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 19mm - 18.8mm

Omega ER25 Collet – Standard Precision is built for dependable, consistent toolholding in ER25 collet chucks. Designed for general machining tasks, this collet delivers tight, repeatable grip with a stated 10 micron (0.01 mm) run-out, helping you achieve cleaner finishes, accurate hole diameters, and longer tool life across a range of operations.

• Precision you can count on – 10 µm run-out minimizes eccentricity at the cutting edge, reducing chatter and producing truer milled features, smoother drilling, and more consistent reaming results.
• Reliable, self-centering clamp – evenly distributes clamping force around the tool shank for balanced operation and less tool deflection during high-speed machining.
• Durable construction – manufactured from hardened, ground steel to withstand cycle-after-cycle use in demanding workshop environments, with tight tolerances that stay true over time.
• User-friendly compatibility – engineered to pair seamlessly with standard ER25 collet chucks and drawbar interfaces, enabling quick tool changes and dependable repeatability on CNC and manual machines alike.
• Ideal for a range of tools – perfect for holding round tooling such as end mills, drills, and small reamers within the ER25 system, enabling precise performance across milling, drilling, and finishing operations.

Size footprint – designed for ER25 applications with a 19 mm overall interface and an 18.8 mm seating interface, giving you a compact, consistent fit for your tooling setup.

Whether you’re equipping a home shop, upgrading a job shop, or refining a precision milling workflow, this standard precision ER25 collet delivers dependable clamping and repeatable results. Pair it with your ER25 chuck for reliable toolholding that helps you achieve the accuracy you demand in every project.
