Stub length end mills, also known as stubby end mills, are cutting tools used in machining operations. They have shorter flute lengths compared to standard or long-length end mills. The benefits of using stub length end mills include:
Rigidity: Stub length end mills are more rigid and less prone to deflection than longer end mills. This rigidity allows for more precise and stable machining, especially when cutting harder materials or in situations where high cutting forces are involved.
Improved surface finish: Due to their reduced deflection and increased rigidity, stub length end mills can produce a better surface finish on the workpiece. This is essential in applications where a smooth surface is critical, such as in mold making or finishing operations
