Anyone know where to buy a diamond-coated hacksaw or coping saw blade?
(USA only) I need something to cut a stuck bearing inner race off of a
small motor shaft and I'm sure it's hardened steel. I looked on google
and only found Australian listings. A bearing puller is no good since
it's right against the commutator and impossible to get anything
behind it.
