No reading errors due to scales and vernier. No time-wasting with arduous approximations of angle values. The advantage of the Felder degree index is that the stop is set and fixed without losing time or making reading errors. Highly precise index positions allow for the accurate production of polygons, e.g. 5.625º (32 sided), 11.25º (16 sided), 22.5º (8 sided). In addition, index positions at 15º, 20º, 25º, 30º, 35º, 40º and 45º can be used when working in slide to cut or push to cut mode. Every index position is equipped with a length compensator. The highly precise Felder degree index system is adjusted at the factory. Every index position also has individual fine adjustment. This cost effective index system integrates well into the machine design and will increase your productivity.
