When making finish passes you would reduce this number to 10 especially when using a 116 ball nose end mill for detail carving It will give you the best finish results FEEDS AND SPEEDS SPINDLE SPEED If you are using a STEPCRAFT HF500 spindle then this number would control the RPM If you are using a Dremel or a router such as
