Featuring the same sharpening system as the BMS200, the BMS250 features an auto-shutoff when the blade is finished, and also has a heavy-duty hood to enclose the blade during sharpening that includes an exhaust vent for use with a vacuum system, for a clean air environment.

All Wood-Mizer sharpeners use the highest quality CBN, full-profile grinding wheels that sharpen tooth-to-tooth each time, and come ready to sharpen right out of the box, not requiring any dressing. The BMS200 uses 5” grinding wheels, which come in various profiles.

If you’re looking for an heavy duty automatic sharpener that can hold up and deliver great results on a daily basis, the BMS250 is your answer.
