Description
High-Precision C16-ER11M x 150L Cylindrical Shank Baby Collet Chuck Holder
The MTM C16-ER11M-150L cylindrical shank baby collet chuck holder delivers exceptional rigidity and high-speed precision for intricate CNC milling, mold making, and micro-machining. Its straight shank (Ø16mm) and compact ER11M mini nut provide maximum tool clearance in deep cavities.
Key Features & Benefits
- Extended Deep-Cavity Reach: 150mm straight shank allows deep reach into recessed workpieces without tool interference.
- High-Speed Dynamic Balancing: Pre-balanced up to 15,000 RPM for smooth operation, reduced chatter, and longer tool life.
- Sub-Micron Grinding Accuracy: Precision ground on CNC cylindrical grinding machines to ensure high concentricity and runout accuracy ≤ 0.005mm.
- Slim ER11M Mini Nut: Compact outer diameter reduces collision risks during fine detailing and EDM electrode milling.
