Dogbone Fillet Tool
A dogbone fillet is used with CNC routers to overcut in a corner when the part you are making needs to fit tightly with another part, typically a cornered rectangular shape.
This tool may be used with lines, rectangles and polygons.
There are two types of fillet shapes to choose from. With a semi-circle overshoot shape, the fillet extends the first line segment that you click on.
