Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 17mm - 16mm

Omega ER40 Collet Standard Precision - 10 Micron Run-Out - 17mm - 16mm

When precision matters in everyday machining, this ER40 collet is designed to keep your toolholding consistent and reliable. Built for humming along with an ER40 collet chuck, it delivers a true, repeatable grip that minimizes run-out and preserves accuracy across milling, drilling, and light finishing tasks.

Key benefits you’ll notice in real-world use:

• 10 micron run-out for improved concentricity and tighter tolerances, resulting in cleaner holes, smoother finishes, and fewer tool deflections during cut operations.
• Standard precision design tailored for general machining work, offering dependable performance without unnecessary complexity.
• 13.8? precision-ground bore (steel construction) that maintains a solid, precise grip on round tooling, reducing grip play and chatter under load.
• Compatible with common ER40 chuck systems, including tool shanks in the 16 mm to 17 mm range, making it a versatile choice for workshops that run a mix of small-diameter tools.
• Durable, long-service design built to withstand frequent tool changes in busy production or hobbyist environments, helping you maintain consistent results over time.

Ideal for machinists, hobbyists, and shop floors where repeatable accuracy matters for small-diameter tooling. Use this ER40 collet for precision end mills, drill bits, and small-bore tooling in standard milling setups, ensuring each tool is held securely for every pass. To maximize performance, pair with proper torque during tightening, keep the contact surfaces clean, and inspect for wear to maintain peak concentricity.
