Should I Buy a Drill or an Impact Driver?
One of our readers posed the question on Facebook – “Should I buy a drill or an impact driver?”
That’s a great question and one that comes up pretty early in the apprenticeship training process. Here’s the short answer – buy a drill if you can only afford one, but get a kit with both if you can.
Should I Buy a Drill Or An Impact Driver?
Let’s flush this out a bit more and give you some solid rationale to make your purchase decision easier. It’s all based on how each tool works. The drill spins with a constant amount of pressure on the chuck until it has no more power to continue. That is unless you engage the clutch. We’ll talk about that in a moment. An impact driver has a hammer/anvil mechanism inside. As the hammers (usually two, but Hitachi has three) spin, they strike the anvils on their way around.
To understand the difference, imagine pushing as hard as you can against a tree versus punching it. With the push, you have less power on the tree itself, but you’re able to sustain it constantly. With the punch, you drive much greater force, but only for a moment. A drill is akin to a push and an impact driver is like the punch.
So that makes it seem as if the impact driver has more power – and it does. So why buy a drill instead?
Drill Vs Impact Driver Functions
An impact driver’s driving mechanism and power make it a screw driving specialist. No drill comes close to the speed and ease of driving fasteners with an impact driver. You can even do light socket work with an impact driver. Be sure to use impact-rated sockets for that task, though.
When it comes to drilling holes with twist bits, spade bits, Forstner bits, self-feed bits, hole saws, etc., the impact driver is capable of getting the job done, but it’s much rougher. And if you’re looking for smooth function and clean holes, all those impacts work against you. This is where the constant pressure of a drill is the much better option.
Why You Should Buy the Drill
So the drill takes care of drilling and boring tasks much better than an impact driver, even though you could use an impact for that task. In fact, some brands even make drill bits specifically for your impact driver. You’ll just get better results with the drill.
The drill may not be as fast as an impact driver on screws and other fasteners, but you won’t lose the quality of the result by using it. In fact, your results can actually improve. Using the clutch on a drill allows you to dial in the exact amount of driving force you want for the material you’re working with and the fasteners you have. That can leave a very clean, precise finish when all your screws are perfectly flush with your workpiece. Impact drivers tend to offer a little less finesse in the finish department.
But You Should Really Buy Both… if You Can Afford It
In an ideal world, you should have both tools so you have the best tool for all drilling and driving applications. It also gives you the ability to have your drill bit in your drill for pilot holes and your driver bit or nut driver on your impact driver to drive the fastener. Since you don’t have to switch bits for each fastener, you’re much more productive.
But let’s take a look at reality for a moment. If you’re looking for something top of the line like the Milwaukee 2704-22 and its 1200 in-lbs. of torque, you’re looking at $299 to get a kit with batteries. You’ll need to tack on another $70 to add the impact driver.
Top of the line is nice to have and seasoned Pros love them, but maybe you’re aiming a little too high. After all, you don’t – or shouldn’t – be buying the same house your parents spent 20 years saving for the moment you graduate college and get married. You’ll wind up with more debt than you can carry and that can happen with your tools as well.
You can look to Ryobi, who offers a nice blend of entry-level performance with outstanding value and pick up a kit with batteries starting around $100. You can move another step up into Pro performance with a Ridgid kit starting around $150. With the money you’re saving, you can add tools more quickly or save to buy those premium tools with cash rather than adding the interest you’ll accrue on a credit card.
With the extra money in your pocket, you’ll even be able to afford to take your wife out for a Thursday lunch date without worrying about credit card debt.
