The job is to make a bushing for a golf cart clutch. ID has to be 1.62
and OD 1.80 or so. 1.5" pipe is fairly close but it just turns pretty
bad because the steel tears out leaving a poor surface. Made a hi
speed tool with about 1/8" radius and turned at 190 rpm and I get a
decent but not good surface. Carbide was much worse than HSS. Still

I'd try a HSS bit with just an RCH of radius. Stone it razor sharp. Use
coolant and turn the RPM WAY up. Should stop the tearing.
