Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 3.5mm - 2.5mm

The Omega ER40 Collet is a precision-engineered clamping solution designed for round tooling in standard ER40 collet chucks. Built for consistent performance, this collet delivers a tight, reliable grip with a 10-micron run-out, helping you achieve cleaner cuts, improved dimensional accuracy, and repeatable results across production runs.

• 10-micron run-out precision: minimizes tool deflection and concentricity errors, yielding superior surface finishes and tighter tolerances.
• ER40 compatibility: optimizes toolholding in standard ER40 chucks for quick, secure tool changes and dependable grip.
• Small-diameter efficiency: specifically designed to securely clamp shanks in the 2.5–3.5 mm range, making it ideal for precision milling and drilling tasks.
• Rugged construction: engineered from hardened steel with precision-ground surfaces to withstand demanding machining environments and provide long service life.
• Versatile machining partner: excels in pocketing, slotting, finishing passes, and other operations where repeatable concentricity matters.

Use cases include high-precision milling, fine-detail drilling, and micro-machining where consistent run-out directly influences tool life and part quality. For best results, ensure the ER40 chuck is clean and fully seated, tighten to the recommended torque, and verify performance with a simple test cut before committing to production runs.
