Precision-Machined ER11A Collet Chuck for CNC Tools

Crafted from high-grade steel with hardened surfaces, this ER11A collet chuck ensures exceptional grip and minimal runout (≤0.01mm) for ultra-precise CNC milling, engraving, and drilling operations. The C8 straight shank design guarantees compatibility with most CNC routers and spindles, while the 100mm extended length provides enhanced reach for deep cavity work.

Custom-Tailored for Industrial-Grade Performance

Features a proprietary heat treatment process that boosts durability by 40% compared to standard chucks, making it ideal for prolonged high-speed operations (up to 25,000 RPM). The micro-tapered bore maintains consistent clamping force even during aggressive cutting of metals, plastics, or composite materials.

Universal Fit with Zero-Tolerance Engineering

Designed to seamlessly integrate with ER11 collets (1-7mm capacity), this chuck eliminates tool slippage in precision applications like PCB fabrication, jewelry making, and aerospace component machining. The knurled grip surface allows effortless hand tightening without specialized tools.
