my brother in law wanted to replace the bearings in an electric motor that was no longer made or for sale, hes looked for a few months now.
the bearings are seated in a blind hole and he had no way to remove them easily from a recess in the housing,
that motor housing is likely to be damaged if subjected to much abuse,
parts like alternators, starters, power steering pumps, and super chargers have these bearings
I suggested he purchase a small recessed bearing puller tool, as that's the ideal tool.
as the cost of the tool and bearing would be far lower than the motor replacement ..if he could even find one.
I offered to pay 1/2 the cost of that 689/2b tool set,
or some similar quality tool set,

if I keep the tool after he used it...as he's very unlikely to ever need it again anyway
and yes it way overpriced and less expensive tools are available

and yeah a bolt wrapped with tape and grease can be used,
in some applications like crank pilot bearing removal
yes there are other options
I've seen guys simply TIG weld a 10" long bolt,
inside the worn recessed bearing,
and use it as a handle to pull the defective bearing out,
but that's not always an option due to heat or bearing access issues
