What tool does one use to cut bearing races.  Both linear and circular.  
Ball burrs don't seem to be perfectly round and I assume that the races 
need to follow the same radius as the ball bearing.  Thanks in advance 
for your help.  Dave Armstrong

Russ,

You're right about them being hard, but I think the material is usually
52100 Steel - Even harder than 5160. (This according to
Torrington/Fafnir catalog)

Unless I'm misunderstanding you don't "cut" bearing races except in a
roughing operation.  Most bearing races are made from a hardened 5160,
and that stuff is plently hard.  Most bearing races are roughed in,
hardened and gound to final size.
