High Precision ER20 Collet, 0.005-0.015mm Runout, 65Mn Steel, 0.50mm Collopsible Capacity
Brief introduction
High Precision ER COLLETS , also known as spring collet, is mounted on a drill milling machine, drilling and milling chuck, its function is to clamp drill cutter or knife. Er flexible collet is currently the most used. Its stable performance, high accuracy by the majority of manufacturers trust. All products are precision grinding, in line with the German DIN 6499 specifiCATEEions precision manufacturing.

The term "precision ER collet" refers to a specific type of collet used in machining and tooling appliCATEEions. ER collets are a type of spring collet that are commonly used in milling machines and lathes to hold and secure cutting tools or workpieces.
The term "precision" in this context refers to the high level of accuracy and repeatability that these collets offer. Precision ER collets are designed to provide a tight and secure grip on the tool or workpiece, ensuring minimal runout and maximum precision during machining operations.
These collets are available in various sizes to accommodate different tool diameters, and they are typically made from high-quality materials such as spring steel or carbide for durability and long-lasting performance.
Overall, precision ER collets are an essential tooling component for achieving precise and accurate machining results. They are widely used in industries such as aerospace, automotive, and manufacturing.
