ER11 Collet Chuck Set – Precision Extension Rod for CNC, Milling, and Lathe Applications • Complete ER11 Collet Chuck Set: Includes one motor shaft extension rod and matching ER11 collet. Designed for use with straight shank tools up to 1/4 inch diameter, compatible with ER11 tool holders. Ideal for hobby machining, CNC projects, and precision milling operations. • Extended Reach for Deep Hole Machining: Features a long extension rod that enables access into deep cavities during cutting or drilling. The elongated body design maintains proper alignment while reaching difficult areas, ensuring accurate results for detailed metalworking and component fabrication. • Enhanced Cutting Stability: Shaft and outer diameter surfaces are precision ground to minimize vibration and imbalance during speed rotation. This refinement helps deliver smoother cuts, greater accuracy, and increased tool life, even in demanding continuoususe conditions. • Durable Steel Construction: Manufactured from quality steel with a silver and black finish, offering strength and resistance to wear and deformation under normal operating loads. Suitable for repetitive use in workshops and production environments. • Practical Applications: Performing fine CNC milling tasks that require extended tool reach without sacrificing accuracy Lathe work on components with deep internal channels or recesses Precision drilling projects where stability and low vibration are critical This ER11 collet chuck set delivers reach, precision, and durability for both professional and hobby machinists, making it a reliable solution for tasks involving extended tool access and stable, speed operation.
