Omega Products ER20 Collet Standard Precision - 10 Micron Run-Out - 14.5mm - 14.3mm

Introducing the Omega ER20 Collet – Standard Precision, a trusted toolholding solution engineered for dependable performance in everyday machining. Built to fit into an ER20 collet chuck, this collet delivers consistent grip and true concentricity, helping you achieve cleaner cuts, tighter tolerances, and longer tool life across a wide range of milling and drilling tasks.

Why this ER20 collet stands out

• 10 micron run-out for exceptional precision. A tighter tolerance means your end mills and drills stay more coaxial with the spindle, reducing wandering cuts and improving surface finish.
• Standard precision construction designed for general purpose machining. Ideal for everyday workflows that demand reliable clamping without specialized tooling.
• Size range 14.5 mm – 14.3 mm aligns with common ER20 chuck specifications, ensuring a snug, repeatable grip and minimizing play under load.
• Hardened steel with a precisely ground bore and reinforced slots deliver uniform clamping force and repeatable performance through many cycles of use.

Use cases and applications

• Milling aluminum, brass, and plastics where accuracy and surface quality matter – from small parts to mid-sized components.
• Drilling and pocketing operations where consistent run-out translates to accurate hole sizes and cleaner edges.
• Engraving and precision feature work that requires tight tool alignment and minimal deflection.

Practical tips for maximizing performance

• Pair this ER20 collet with a compatible ER20 chuck, insert your tool shank, and snug the nut before final tightening to ensure even clamping pressure.
• Choose tools that fit within the ER20 range to fully leverage the 10 µm run-out advantage for repeatable accuracy.
• Keep the bore free of debris and burrs; a clean, burr-free interface maintains consistent grip and minimizes run-out over time.
• Use appropriate feeds and speeds with adequate coolant or lubrication to extend tool life and maintain precision during heavy cuts.

Omega’s ER20 Collet – Standard Precision is the solid choice for professionals and hobbyists who demand trustworthy toolholding, predictable performance, and consistently tight tolerances for everyday machining tasks. If you value repeatable accuracy, easy interchangeability, and durable construction, this collet is designed to meet those needs and keep your workflow moving smoothly.
