1. What is an ER40 collet?
An ER40 collet is a precision tool-holding device used in CNC machines, designed to securely grip round-shank tools like drills, reamers, and end mills. It belongs to the ER (Extended Range) collet system, known for its wide clamping range and high concentricity. ER40 collets are larger in size and are ideal for holding tools with larger diameters, typically ranging from 3mm up to 26mm.
2. What is the max size ER40?
The maximum clamping size of an ER40 collet is 26mm, depending on the specific collet in the set. Each collet also has a collapse range of approximately 0.9mm, meaning a 26mm ER40 collet can clamp tools from 26mm to about 25.1mm securely.
3. What does ER20 collet mean?
An ER20 collet is a medium-sized collet in the ER series, used to hold cutting tools with diameters ranging from 1mm to 13mm. The "ER" stands for Extended Range, indicating its flexibility in clamping different tool sizes. ER20 collets are commonly used in CNC milling, tapping, and drilling applications, offering precision, vibration control, and compatibility with a wide variety of tool holders.
