I use it on a standard 14" band saw to cut 6-8" shell blanks that are 5" thick. /2" plywood with guides at the bottom). I can take a piece of split wood and turn it in under 1 minute and get a perfect circle (transition from lengthways to crosscuts). EASY goes through old maple and sassafras - that Sawdust cleans very well and the kerf is wide enough to make tight circles For <$12 it's great!
