Might be 1/4hp which is a bit low. Says NVR fitted but not shown. I think I'd fit 1/2 -3/4 hp 3 phase motor on it and add an inverter as well as a new cone pulley for electronic variable speed and max torque when needed.
Once you have had a continuously variable speed machine such as a drill, you won't want to go back to a basic one.
Good Luck

Just need a VFD, some cable, and time really. @Bob, Do you have any recommendations for the VFD or are they mostly similar Chiwanese boxes? Thanks for your patience, sorry if it's a stupid question!

Actually the taper on the drill is the Jacobs taper Where the chuck has the 'female' part and the drill spindle has a c.3/4" to c.5/8" taper, as this is thinner than the B16, I wondered if I could get a kind of topless thimble i.e. outside diameter and taper to fit a B16 and the inside to fit a JT2. I shall have a look at the places you kindly recommended and see what's available,
Thanks again!
EDIT actually Chronos have a JT2 Jacobs keyed chuck which will do 13mm which is probably fine.
