Omega Products ER11 Collet Standard Precision - 10 Micron Run-Out - 7mm - 6.5mm

Precision matters in every pass of the cut, and the Omega ER11 Collet (Standard Precision) is built to deliver dependable performance in small-diameter machining. This ER11 collet is engineered for a tight, repeatable grip on tooling when used with an ER11 collet chuck, helping you achieve cleaner cuts, better surface finishes, and reliable tool life in general-purpose machining tasks.

Key features that matter in real-world work

• Ultra-tight run-out: 10 micron run-out (0.01 mm) to maximize concentricity and minimize tool deflection during milling, drilling, or light reaming.
• Standard precision, built to last: Precisely ground and hardened surfaces ensure consistent clamping force and long-lived performance, even after repeated tool changes.
• Direct compatibility with ER11 setups: Designed to pair seamlessly with standard ER11 collet chucks for reliable integration into your existing CNC or manual milling workflow.
• Size range for common small tooling: Optimized for tooling in the 6.5 mm to 7.0 mm range, making it a practical choice for hobbyists and professional shops that frequently work with mid-range shanks.
• Stable clamping for better finishes: Uniform gripping surfaces and smooth interior allow tools to remain centered under load, reducing chatter and improving finish quality on small-diameter workpieces.

Ideal use cases

The Omega ER11 Collet is an excellent choice when precision and repeatability are critical in everyday machining. Use it for:

• Milling small-diameter end mills and drills where concentricity directly impacts hole size and surface finish.
• Engraving or micro-machining tasks that demand consistent tool alignment through multiple tool changes.
• Prototype and small-batch production work where predictable clamping behavior translates to faster setups and fewer retries.
• Any project that benefits from tight tolerance, minimal run-out, and reliable tool retention in an ER11 chuck.

Why this matters for your workflow

Run-out directly influences cut quality, tool wear, and surface finish. A 10 micron run-out ensures the tool tip stays closer to the intended centerline, which translates to smoother cuts, fewer pass corrections, and longer tool life. When you’re swapping tools frequently on a compact CNC or drill-mill, having a standard-precision collet that consistently grips without excessive play reduces setup time and the risk of misalignment mid-cycle.

Practical tips for optimal performance

• Inspect both the collet and the tool shank for burrs or contamination before clamping; even small debris can impact run-out.
• Keep the interior bore clean and lightly lubricated to preserve smooth seating and minimize wear over time.
• Use the collet within its designed size range (6.5–7.0 mm) to maintain the claimed 0.01 mm run-out specification.
• Pair with a well-maintained ER11 chuck and a stable, rigid machine setup to realize the full precision benefits.

Choose the Omega ER11 Collet Standard Precision for dependable, repeatable clamping in everyday machinist workflows. It’s a practical, no-nonsense solution when you need precision without compromise on your 6.5–7 mm tooling depth and diameter range.
