SK40
SK DIN 69871 connection is the most typical and more ricognizable interface for tool holders, the most used in certain fields like stone and glass working.Thanks to its versatility and compact design, it was the first standard to surge as real benchmark for the entire category of CNC tool holders. Its usage is comonly limited to operations under 12.000 RPM, unless provided with a special extra balancing process. The connection with the electrospindle is made through a pull stud screwed on the top of the cone.
