Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 6mm - 5mm

Engineered for dependable, repeatable accuracy, the Omega ER40 Collet Standard Precision set is your go-to solution for secure tool gripping in small-diameter machining. Built to fit standard ER40 collet chucks, these collets keep tooling centered with exceptional consistency, so every cut is clean, every drill is true, and finish quality stays high across tasks.

Key features designed to improve your workflow:

• 10 micron run-out tolerance — minimal lateral deviation translates to tighter tolerances, smoother finishes, and longer tool life in milling, drilling, and precision boring.
• Standard ER40 compatibility — reliable, quick setup with common collet chucks found in shops and home workshops alike.
• 5–6 mm tooling range — optimized for small-diameter cutting tools, providing secure clamping for tasks from micro-milling to delicate drilling.
• Solid, precision-ground construction — crafted from hardened steel to resist wear and maintain tight tolerances through heavy use.
• Consistent clamping performance — reduces run-out-induced chatter and tool deflection, helping you achieve repeatable results batch after batch.

Designed for makers, hobbyists, and professional machinists alike, this ER40 collet set is ideal for people who demand precision in everyday work—whether you're fabricating small components, prototyping parts, or performing intricate engravings. It’s especially valuable when your workflow relies on tight tolerance for diameter and concentricity, such as jewelry tooling, electronics enclosures, or miniature mechanical assemblies.
