Achieve ultra-low runout, exceptional vibration dampening, and high clamping force during high-speed milling, reaming, drilling, and finishing operations with industrial-grade ER Hydraulic Collets (hydraulic expansion sleeves for ER chucks). Designed with a standard ER taper profile on the outer shank and an internal hydraulic clamping expansion chamber, these heavy-duty collets insert directly into standard ER collet chucks. By combining the universal compatibility of the ER taper system with hydraulic clamping technology, they deliver sub-micron concentricity, superior thermal dampening, and uniform radial clamping pressure around the tool shank to prolong cutting tool life and improve surface finishes.
