Your drill is not an impact driver, and your stripped screws are proof

I drove probably ten thousand screws before I knew there was a better tool for it. My Ryobi drill handled fasteners the same way it handled boring holes — full torque, full speed, same bit. Then I picked up a Ryobi impact driver, used it for one afternoon on a deck project, and immediately understood why half my screws had chewed-up heads. The drill was never the right tool for driving fasteners into structural work. I just didn't know there was a different one to reach for.

If your screws keep stripping out or your driver bits wear down faster than they should, the problem probably isn't the screws or the bits. It's the tool. Here's what's actually happening — and why keeping both in your garage makes every fastening job cleaner.

They're built around completely different mechanisms

One rotates continuously — the other hammers

A drill works by spinning the chuck directly. Pull the trigger, the motor turns, the bit turns — continuous and steady. That's exactly what you want when you're boring a hole through wood or metal. The problem comes when you point that continuous spin at a screw head approaching flush. There's no built-in stopping point. The motor keeps pushing, the bit keeps spinning, and when resistance spikes at the wrong moment, the bit skips out of the head and starts grinding metal.

An impact driver operates on a completely different principle. Inside the mechanism, a hammer strikes an anvil in rapid succession under load — each strike adds a sharp rotational jolt rather than continuous force. The bit stays seated in the screw head because the contact is brief and repeating rather than one sustained push. That distinction sounds subtle on paper. The first time you drive a long lag bolt with an impact driver, it becomes obvious.

Why drills strip screws (and why it keeps happening)

The physics of cam-out, explained simply

Cam-out is what happens when a driver bit climbs out of a screw head mid-drive. The angled walls of a Phillips or Pozidriv recess are designed so that torque naturally tries to eject the bit — a feature in manufacturing settings, meant to prevent overtightening on an assembly line. In your garage, it just destroys screws.

A drill's continuous rotation gives cam-out every opportunity. Once a screw approaches flush and resistance spikes, the torque redirects upward, and the bit spins free. Go faster, and it happens sooner. Press harder to compensate, and you drive the head further into the material while still chewing up the recess.

Learning how the drill's clutch settings manage torque does help — dialing it in reduces the damage considerably. But the clutch works by cutting power once resistance hits a threshold. It doesn't change the continuous-rotation nature of the tool, and cam-out happens in the moment before the mechanism trips.

What the impact driver was actually designed to do

Long screws, lag bolts, and anything that fights back

The hammer-and-anvil action of an impact driver is a direct solution to the problem drills create. Each strike drives the fastener forward while keeping the bit pressed into the head. Under a heavier load, the mechanism fires faster. You can drive a 2.5-inch deck screw into pressure-treated lumber without a pilot hole, without fighting the tool, and without the head stripping out — because the contact pattern never gives cam-out a foothold.

Out of all the tools I didn't know I needed until I used them, the impact driver was the one that most changed how I thought about fastening. I'd been running the drill on shelf brackets, deck boards, fence posts — all of it. Switching to the impact driver on those jobs felt like finding out I'd been using the wrong bit style for years. The difference showed up on the first screw.

Repetitive fastening is where the gap is hardest to ignore. A long run of deck screws with an impact driver is fast and consistent. Each one seats audibly. You stop watching every head and just listen for the sound that tells you it's done.

Keep the drill — it still has jobs the impact driver can't do

Drilling holes, delicate materials, and precision work

The impact driver earns a permanent spot in the garage, but it doesn't replace the drill. Boring holes requires continuous, uninterrupted rotation. The hammer-and-anvil mechanism fires under driving load, but it isn't built to keep a spade bit or hole saw cutting cleanly through sustained resistance. Because of the attachment mechanism, you can’t even use an impact driver for drilling, but if you could, you'd get chatter, wandering, and rough results.

Delicate work also stays with the drill. Cabinet hinge screws, thin trim, anything where half a turn too many would split the wood or strip a small fastener — the drill's clutch handles that with more precision than impact power allows. Set the clutch low, run a test screw, and the tool tells you when to stop.

If you're building out a Ryobi ONE+ collection, both tools share the same 18V battery. You're not buying into two separate platforms — just adding a second tool to infrastructure you already own. As a bare tool, the impact driver slots into the ONE+ lineup somewhere in the $50–$70 range, and one weekend of real fastening work makes that easy to justify.

Two tools, one platform — and the screws finally seat right

Once I started reaching for the impact driver on fastening jobs and keeping the drill for holes and precision work, stripped screws became rare. The distinction sounds minor until you're twenty minutes into trying to salvage a chewed-up bolt mid-project. The two tools don't compete — they cover different ground, and most homeowners only work that out after ruining enough hardware to make the lesson stick. If you're already running ONE+ batteries, the impact driver is one of the most straightforward additions in the lineup. Drive one long screw with it, and the drill never gets that job again.
