Thanks for the suggestions so far. They seem to be OK for the steadies but I would want it to work with steel screw in pegs as well. I am looking at a Lidl 18V with 2 batteries at
Don't be tempted to buy the leading supermarkets Value or Smart Price cordless drills. I bought one of these last year for my steadies and they certainly do not have enough power to complete the job. They lack power and therefore I would certainly recommend paying that little bit extra and going for the more powerful 18v drills.
