ABSTRACT:
A device for sharpening band saw blades while the blade is in place. A grinding disc is propelled toward and away from the saw blade to grind the teeth. While the disc is being retracted, the band is moved one tooth spacing and held there by an indexing device so that the next tooth is in position to be ground. Adjustments are provided to accommodate different spacing of the teeth in different bands. The power unit for the grinder may be a common drill motor.
