If these valve covers are all you're doing, you can do it with the drill - it'll just take a while. After all, Caswell sells a kit just for using a drill, so they must think it works...

If you're going to do very many more parts, _then_ it might be worth it to get better equipment.
My Dewalt Grinder is 11,000 rpm's, I ordered an adapter and a few pads from Caswell. My drill was'nt getting it done. It is only pushing around 3,000 rpm's, I probably put about 5 hours on just one of my covers.
