Achieve superior runout accuracy and extended reach during complex milling, drilling, and reaming operations with industrial-grade Collet Holders (straight shank ER collet extension chucks). Engineered with a precision-ground cylindrical shank and a low-profile clamping nut, these extended chucks are designed to reach deep cavities and tight tooling envelopes where standard toolholders cannot clear. The precision-machined internal taper securely seats ER collets, providing maximum mechanical grip, minimal radial deflection, and smooth torque delivery across high-speed CNC machining cycles.
