We know you've heard it many times before: you get what you pay for. If that was absolutely true, there would no reason for a site like this. You would just decide how much you want to pay and find a cordless drill for that much. But in my experience it tends to be true in the very general case. Festool Cordless Drills are by far the most expensive and also the best. But we recommend Makita drills in some of our categories and we think they're better than drills that cost more. So if you're looking for a cheap cordless drill, you're still looking for the best value for your money. You're not going to get a Festool or even a Makita, but you can still get a quality drill and avoid the drills that aren't worth your time or money.
For the cheapest cordless drill we've selected the Black & Decker 9099KC 7-1/2-Volt Cordless Drill. It's not the abolute cheapest drill you can find, but we've think it's cheapest you should consider buying. Here's why we selected it:
A step up from the cheapest cordless drill is the Ryobi 9.6-Volt Cordless Drill.
