Blade width options
are 1/4", 3/8", 1/2", 3/4", 1", 1 1/4", or 1 1/2" widths. For straight sawing, use the widest blade possible. In contour work, select your blade width based on the minimum radius listed below. Radius limits vary with material type and thickness, feed force, and pivot point. The following radii are based on cutting 1" thick metal.
1/4" wide blade cuts a 1/2" minimum radius
3/8" wide blade cuts a 1 1/16" minimum radius
1/2" wide blade cuts a 1 3/4" minimum radius
3/4" wide blade cuts a 4" minimum radius
1" wide blade cuts a 5 1/2" minimum radius
1 1/4" wide blade cuts a 9 1/2" minimum radius
1 1/2" wide blade cuts a 12 1/2" minimum radius
