Picked up a 1.5" round of something out of my scrap box to make an adapter. Turned at about 950RPM with carbide. Absolutely beautiful finish taking small cuts. However, the swarf looked like semi-coarse steel wool and would sometimes spark and actually glow and catch to flame. Next operation was to drill a through hole. Easily done: two steps and a reamer to 7/16" ( the 0ther side will be 3/4"). So far no problem...
Now to the bandsaw. Would scratch but not cut. Maybe a dull blade? No, replaced it not long ago. Took it out and tried it with a hand saw. No cut. Then tried a file, scratched it.
Why would this metal turn and drill easily and seem to be hard when sawed.
