Learn more about Klarna
Omega’s ER16 Collet is a coolant-sealed, standard-precision toolholder accessory designed for round-shank cutting tools used in milling, drilling, and precision machining. With run-out under 10 μm, it helps deliver consistent concentricity for clean finishes and longer tool life across a range of applications. Its 3–10 mm clamping range makes it a versatile choice for common end mills and small-form tooling.
Note on design: newer versions remove the rubber seal on the nose, and the slot arrangement is designed so longitudinal slots do not overlap at the centre, reducing coolant leakage. To preserve the seal and performance, use only round-shank tooling with no clamping flats; tools with flats will render these collets ineffective.
- Ultra-low run-out (<10 μm): Delivers consistent grip and true concentricity for better surface finish and longer tool life across demanding milling and drilling tasks.
- Coolant-sealed nose with leakage prevention: Non-overlapping centre slots minimize coolant escape, keeping the work area cleaner and reducing coolant waste, even during extended cycles.
- 3–10 mm clamping range for round shanks: Flexible sizing for common tooling, with guidance to avoid clamping flats so the seal remains effective and reliable.
This ER16 collet supports efficient workflows by providing secure, precise tool gripping in a clean, coolant-controlled environment. Its reliability helps reduce rework, improve cut quality, and enable smoother tool changes, keeping your project on time and within spec.
