When it comes to stating a new engine the only way I can do it is with an electric drill, sometimes the cordless drill is not fast enough and I have to resort to the plug in type.
I have 3 sizes 6, 8 and 12mm, they are made by drilling a hole a couple of mm below the top and then with a round file the same size as the hole file a grove half a hole out, when it breaks through to the original hole it will naturally work its way around to give a curve.
