Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 23mm - 22mm

Omega ER40 Collet Standard Precision is engineered for dependable, repeatable tool holding in your ER40 collet chuck. This standard precision collet is designed to securely clamp round tools, delivering consistent performance across a broad range of machining tasks. The result is steadier cuts, improved surface finish, and longer tool life in everyday milling and drilling work.

Key features that matter in real-world shop floor use

• 10 micron run-out for precision applications: reduced run-out translates to truer tool paths, finer tolerances, and cleaner finishes, especially on smaller-diameter cutters and delicate materials.
• ER40 compatibility with standard ER40 collet chucks: quick tool changes and reliable grip for a wide variety of end mills, drills, and reamers commonly used in CNC milling and manual machining.
• Robust, repeatable clamping designed to resist tool deflection during heavy cuts, helping you maintain dimensional accuracy across multiple parts.
• Designed for general-purpose machining: a dependable choice for everyday milling, drilling, and light reaming tasks in steel, aluminum, and plastics.

Why this matters for your shop workflow

When your tooling holds true, feeds and speeds become more predictable, and you spend less time deburring and measuring. The 10 micron run-out specification provides a solid baseline for achieving consistent results—fewer tool marks, tighter hole centers, and improved repeatability across batches.

Ideal uses

• General milling and drilling with ER40 collet chucks
• End mills and drills that require tight ring grip and minimal run-out
• Production environments where repeatability and finish quality are priorities
