Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 19.5mm - 19.3mm

Omega ER25 Standard Precision Collet Set — 10 Micron Run-Out

Engineered for reliability and consistent performance, the Omega ER25 Standard Precision Collet delivers exceptional grip for round tooling in an ER25 collet chuck. With a guaranteed 10 micron run-out, this collet minimizes tool deviation and maximizes your cutting accuracy across a wide range of general machining tasks.

Key benefits at a glance

• Ultra-low run-out — 10 µm ensures true concentricity, improving surface finish and dimensional accuracy on every pass.
• Rigid, precise construction — built to maintain accuracy under typical shop conditions, reducing chatter and tool deflection.
• Easy compatibility — designed to fit standard ER25 collet chucks, making it a straightforward upgrade for existing setups.
• Range-focused performance — specifically tuned for the ER25 system with shank sizes in the 19.3–19.5 mm range, aligning with common small-diameter tooling needs.
• Versatile for multiple operations — ideal for milling, drilling, reaming, and precise engraving where steady, concentric grip matters.

Why choose an ER25 collet for your workflow? The ER25 family is known for uniform clamping pressure around the tool shank, delivering balanced grip and repeatable results across long runs. This standard precision variant from Omega maximizes that advantage with tighter run-out control, helping you achieve higher accuracy per part and longer tool life by reducing mismatches between tool and workpiece.

Use cases and ideal applications

Perfect for hobbyists and professional shops alike, this ER25 collet shines in:

• CNC milling and routing requiring precise small-diameter tooling
• Micro-drilling and reaming where concentricity is critical
• Engraving and detailing projects that demand clean, defined cuts
• Prototype work where quick, repeatable tool changes matter

Practical tips for peak performance

• Clean shanks and the collet bore before installation to preserve run-out accuracy.
• Torque the collet nut to the manufacturer’s recommended specification to ensure even clamping forces.
• Periodically inspect for wear or deformation; replace worn collets to maintain consistent run-out.

Upgrade your machining precision with the Omega ER25 Standard Precision Collet and experience reliable, repeatable results that keep your projects on target—from initial pass to final finish.
