Omega Products ER16 Collet Ultra Precision is a high-precision clamping solution designed for ER16 collet chucks. It securely holds round shank tools while delivering exceptional concentricity for ultra-precise machining. These collets are ideal for milling, drilling, and finishing tasks where tight run-out matters. Designed for 6–7 mm round tool shanks, these collets help engineers, machinists, and hobbyists achieve consistent results with repeatable tool seating, reducing setup time and improving surface finish. 5 Micron Run-Out: Maintains near-perfect concentricity to deliver consistent accuracy and smoother finishes, minimizing chatter and helping you meet tight tolerances. 6–7 mm Shank Compatibility: Optimized for common 6–7 mm round tool shanks, enabling quick, repeatable tool changes with reliable grip and reduced risk of slippage. Rigid, Precision-ground Construction: Hardened steel bore and carefully manufactured clamping geometry resist wear, preserve tolerance, and endure daily use in demanding shop environments. With these features, you gain dependable, repeatable performance that streamlines your workflow. Near-zero run-out reduces the need for constant rework, helping you achieve precise dimensions faster and with better surface quality. Durable construction and precise manufacturing extend tool life and minimize downtime, making this ER16 collet an reliable choice for CNC mills, drilling, and precision applications.
