Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 3.5mm - 2.5mm

Omega ER25 Collet, Standard Precision — designed for reliable toolholding with exceptional concentricity. This ER25 collet is built to pair seamlessly with a standard ER25 collet chuck, delivering consistent grip and-repeatable accuracy across machining tasks that demand precision.

With a clamping range from 2.5 mm to 3.5 mm, it covers a common spectrum of small-diameter tools used in micro-milling, delicate drilling, and precision engraving. The result is stable tool engagement and minimal run-out, even under high-speed operation.

Key benefits for your workshop

• 10 micron run-out ensures tight concentricity, producing cleaner holes, accurate pockets, and superior surface finishes on aluminum, brass, and steel.
• Rigid, hardened steel construction stands up to repeated tool changes and clamping cycles, extending life and maintaining precision over time.
• Wide compatibility with ER25 collet chucks, enabling quick tool swaps without sacrificing grip reliability.
• Compact, balanced design minimizes vibration and wobble at higher spindle speeds for steadier cuts.

Practical applications

• Micro-milling and engraving tasks where small-diameter tools must remain precisely centered.
• Drilling tight-diameter holes with consistent exit quality and reduced burring.
• Prototype development and fixture work that benefits from repeatable toolholding and predictable results.

To maximize performance, pair this ER25 collet with care: keep shanks clean, avoid excessive over-tightening, and ensure proper tool length to minimize deflection. The Omega ER25 Collet, Standard Precision, delivers dependable accuracy in everyday machining while offering the versatility needed for precise, small-diameter work.
