The full-sized Sorby Hollow Master features a flat bottom for increased stability and control during your woodturning projects. The 1/4" wide HSS cutter can be swiveled to allow the cutter to reach otherwise inaccessible areas inside hollow forms. The included 1" round scraper cutter can be mounted in place of the hollowing cutter for final inside smoothing. Overall length is approximately 24", maximum reach of approximately 8".
