The toolrest is designed to work with the banjo (toolrest base) so that you can get very close to the front and back side of turnings. Our 6″ toolrests are for our large lathes and are made from ductile iron which is stronger than cast iron and will last longer. These toolrests are powder painted and are suitable for both underhand and over hand grips. The blade is 6″ long, the post is 1″diameter, 4 3/4″ long, and the overall height is 6 1/2″.
