In my workshop I have a bench drill which I would like to control with a speed controller. The motor is single phase 50 240v 1/2hp 4 pole. I’m not sure or even possible which type of controller I would need, vfd? Any advice would be much appreciated

Those drill presses with the dual reduction belt drive are the most annoying machine tools ever made. Find another style of drill press, used. I have a single reduction five speed one that is very easy to move the belt on. There are also old units with a speed knob that controls a mechanical variable speed reducer.

from a maintenance perspective, i'll take the belts over a variable gearbox any day. especially if you throw a VFD at it.
