Omega Products ER11 Collet Standard Precision - 10 Micron Run-Out - 4.5mm - 4mm

Omega’s ER11 Collet, Standard Precision, is engineered to deliver dependable, repeatable clamping in an ER11 collet chuck. Built for everyday machining, this collet secures round tool shanks with minimal run-out, giving you reliable grip and consistent performance on small-diameter tooling.

Key features that matter in the workshop

• 10 micron run-out for improved centering accuracy across the clamping range, helping to reduce tool deflection and vibration during cuts. This means more consistent toolpaths and better surface finish.
• Shank clamping range: 4.0–4.5 mm designed to accommodate common small-diameter tooling within a single collet, simplifying setup and reducing the need for multiple sizes.
• Standard precision designation aimed at general purpose machining, making it a dependable choice for routine milling, drilling, and light-duty operations.
• ER11 compatibility specifically intended for use with an ER11 collet chuck, ensuring straightforward integration into existing toolholding setups.
• Consistent performance across machining sessions, so tools stay aligned as you batch-run parts, fixtures, or prototypes.

Ideal for hobbyists and small shops that rely on predictable, repeatable results from compact tooling. If you’re upgrading a handheld or benchtop mill, or outfitting an ER11-based workstation, this standard precision ER11 collet helps you minimize runout, improve cut quality, and streamline tool changes without sacrificing versatility.

In practical terms, you’ll notice steadier feeds and less chatter when engaging small-diameter cutters, leading to cleaner corners, tighter tolerances, and longer tool life. It’s a focused upgrade for anyone who values accuracy in everyday machining tasks.
