I am making a cross drill bushing to use in making my new T handle chuck wrench. I cut off this piece of 1" round 1018 steel and thought the pattern was interesting. Can anyone tell me what causes this? It looks like opposing half circles of the same radius as the part, but offset. There are three facing each other and they are ridges that can be felt. The direction of the saw was running right to left in the picture and from top to bottom. Is this from the part slightly flexing in the clamp, composition of the steel, the blade, the cheap saw? The small burr is the bottom/end of the cut.
I looked at it again and I can also see a reproduction of the center hole. I think this is caused by the weld in the blade.
Curious minds might be interested...
