Default Review: Delta 17-968 variable speed drill press

It runs much better on 220v

How is it better and did you change the switch?

It does not want to stall as easly and seems to have more power.

Do not adjust it unless its running.


Yeah, every time you see one in a store, there's a big sign telling
people not to do that. Is yours harder to turn coutner-clockwise?


The variable speed is obtained by using tapered pulleys that expand and
contract. When turning one direction (CW), you open the pulley inside (this
would be the easy direction). When turning the opposite direction(CCW), you
are attempting to close the pulley halves. If this is done at a stop, you
could break the internal pulley. This account for the difference in torque
required to change speeds.
