Band Saw Blade Radius Guide Band Saw Blade Radius Guide

When cutting circles with a band saw, it is vital to select the correct blade width. The smaller the blade width, the smaller the radius or tighter the circle you will be able to cut out. The width of a blade is measured from the tips of the teeth to the back edge of the blade. This will help you if the blade width is not clearly marked.

Width of Blade Determines Radius of Circle

If the blade width is 1/8-inch, then the minimum radius you will be able to cut is 3/16-inch.

If the blade width is 3/16-inch, then the minimum radius you will be able to cut is 5/16-inch.

If the blade width is ¼-inch, then the minimum radius you will be able to cut is 5/8-inch.

If the blade width is 3/8-inch, then the minimum radius you will be able to cut is 1 ½-inch.

If the blade width is ½-inch, then the minimum radius you will be able to cut is 2 ½-inch.

If the blade width is ¾-inch, then the minimum radius you will be able to cut is 5 ½-inch.

If the blade width is 1-inch, then the minimum radius you will be able to cut is 7-inch.
