An excellent way to improve stability and accuracy in rotating tools applications when applied to Swiss-type and multitasking machines is to improve clamping stability by use of integral collets. What is an integral collet? An integral collet is a tool with a tapered shank for direct mounting on ER collet chucks. When compared to a typical spring collet clamp, the integral collet provides better accuracy and higher rigidity. This feature makes integral collets very promising for use in Multitasking and Swiss-type machines. Iscar offers several tool families with integral collets. Some of them, such as those with MULTI-MASTER adaptations, have internal coolant channels for inner coolant supply.
