An ER20B collet is used to securely hold a cutting tool, like a drill bit or end mill, within the spindle of a CNC machine, primarily for milling and drilling operations where a medium-sized tool is needed, providing a tight grip to ensure precise machining with minimal runout; "ER20" indicates the specific size of the collet within the ER collet system, making it suitable for a range of tool shank diameters within that size range.
Key points about ER20B collets:
Function: To clamp a cutting tool firmly in place during machining operations.
Application: Commonly used in CNC milling and drilling machines.
Size range: Designed to accommodate a range of tool shank diameters within the "ER20" size category.
Benefits: Provides good holding power, high precision, and minimal runout due its design.
