Omega Products ER32 Collet Standard Precision - 10 Micron Run-Out - 3.5mm - 2.5mm

Meet the Omega ER32 Collet — Standard Precision engineered for dependable, repeatable tool holding in ER32 collet chucks. Built to tight tolerances and finished with a precision-ground bore, this collet prioritizes concentricity so your cutting tools stay centered and stable from start to finish of each pass.

Key features that matter in real-world machining:

• 10 micron run-out (0.01 mm) ensures precise alignment of the tool with the workpiece, reducing run-out-related errors and improving surface finish.
• Shank range 2.5–3.5 mm designed to clamp small-diameter tooling securely in common ER32 setups, making it a versatile choice for milling, drilling, and light reaming tasks.
• Standard precision design balances performance and value for general-purpose machining, making it ideal for shop floors, prototyping benches, and maintenance workshops.
• Even contact through a segmented bore (as seen in the image) provides uniform grip around the tool shank, minimizing tool deflection and chatter during high-speed passes.
• Robust construction — crafted from hardened steel with precise finishing to resist wear and maintain accuracy over thousands of changes.
• Easy integration with existing ER32 collet chucks and standard tooling, enabling quick tool changes and consistent clamping performance.

Ideal for engineers, machinists, and workshops that demand dependable performance without compromising on precision. Use this ER32 collet for a wide range of operations—from pocket milling and slotting to drilling and finishing passes—where repeatable accuracy and smooth cutting matter most.

Why this matters in practice: a 0.01 mm run-out can translate to tighter tolerances on your parts, less wear on cutting edges, and a cleaner finish on harder materials. When you pair precise clamping with stable feeds and speeds, you get noticeably better tool life and consistent results across batches.

Maintenance tips for lasting accuracy: keep the bore clean, remove chips after every job, and apply a light coat of suitable lubricant to prevent corrosion. Inspect the collet’s gripping surfaces for wear and replace if any burrs or deformation are present to maintain peak concentricity.
