The steel milling cutters for podiactric use are the range with which it all started in "milling country". Each cutter can be used for multiple purposes. When deciding on your milling cutter purchase, please keep in mind that "too coarse" should NEVER be used on a nail. Also, all cutters with straight grooves, knives or channels are suitable for clockwise and anticlockwise turning handpieces. Only the 11RS series ( spherical toothed), the 81RS series ( large spherical toothed) and the 84RS series ( mushroom toothed) have spiral blade positions and can therefore only be used clockwise. Busch offers a wide range of stainless steel pedicure cutters that are very affordable and do an excellent job.
