CBN Sharpener

Share This Page:

The BMS250 sharpener is made for the professional who needs to maintain their blades with time-saving, assured accuracy. The BMS250 uses a 5" diameter CBN wheel to sharpen the entire profile of the blade. The CBN wheel is directly driven off the single phase AC motor and the surrounding hood confines the oil mist which leads to a cleaner sharpening environment. The hood features an exhaust port where fumes and mist can be drawn out. Loading the blade is easy to manage and the controls allow for quicker setup and operation. Changing the grinding wheel to maintain various profile blades remains simple and efficient.
