Suhner Rotoset drive porting machine can be used for a range of different sized carbide burrs and small diameter abrasives as a result of the variable speed from 11,000 to 25,000 Rpm.
The small tool holder with precision of 6mm or ¼” collett is 320grams in weight. The 7mm drive shaft can be up to two metres long and the 1050W Suhner Rotoset machine can be hung easily, taking the 1.7Kg weight of the shaft away completely.
