Dewalt Hammer Drill vs ONEVAN Impact Tool: Which One Do You Actually Need?

A dewalt hammer drill drills concrete; an impact tool drives fasteners. Here is exactly which one your projects actually need.

Updated 22 Aug 2026 5 min read 6 sections

If you need to drill through concrete or masonry, a dewalt hammer drill is the right tool; if your daily work is driving long screws and tightening bolts, an impact tool gets the job done faster. These two drills look alike, sit on the same battery platform, and are often sold side by side, yet they solve very different problems. Here is what each one actually does, where they overlap, and which one truly belongs in your kit.

What a Dewalt Hammer Drill Does Best

A dewalt hammer drill combines rotary drilling with a hammering action. The chuck spins the bit while a cam-driven mechanism pounds it forward thousands of times per minute, which lets carbide-tipped bits chew through brick, concrete block, and light masonry instead of just skating on top of them.

The key thing to understand is that the hammering is tuned for drilling, not fastening. Yes, you can drive screws with a hammer drill, but the hammer action is mild enough that it mostly delivers what builders call a heavy-duty drill motor with a wide speed range and a high-torque setting.

Reach for a dewalt hammer drill when you are:

Drilling anchor holes in concrete or brick for shelving, railings, or framing
Using dewalt hammer drill bits sized for masonry, since standard wood bits dull fast under impact
Cutting holes through block walls or patio slabs
Working on a corded model with sustained run time for long drilling runs

If your project is drilling into concrete, no impact driver replaces a hammer drill. The two tools are not interchangeable for that task.

What an Impact Tool Does Better

Where the hammer drill hits forward, an impact tool delivers rotational impacts: a spring-loaded anvil slams the socket or bit in a twisting motion. That is exactly what breaks loose a stuck bolt or drives a 3-inch screw into oak without stripping the head or smoking the motor.

The 1 2 impact tool is the faster, lighter daily driver in most shops. It resists kickback, so you can drive fasteners one-handed, and it stops the instant you let off the trigger, which reduces overdriving. If you are assembling furniture, building decking, or doing constant fastening work, an impact tool is the ergonomic winner.

This is also where the torque driver earns its spot. It lets you set a precise torque limit, which matters when you are working on bikes, gear, or any fastener that breaks if you overtighten. A hammer drill has no torque-setting clutch in the way impact tools and torque drivers do.

Cordless vs Corded: Which Dewalt Hammer Drill Fits You

The cordless dewalt hammer drill 20v xr line is the popular pick for good reason. The brushless motor delivers near-corded power, the battery platform shares across the lineup, and you are not tethered to an outlet on a ladder or across a yard. If you value portability and already own 20V batteries, the 20v brushless XR models are hard to beat.

A dewalt hammer drill corded model is the play for someone doing long runs of drilling through concrete where run time beats portability. No battery swap, no sagging power as the pack drains, and the tools tend to cost less than the equivalent brushless kit.

The honest advice: buy cordless if you are a general DIYer or a mobile tradesperson, corded if your week is mostly dedicated masonry drilling. Read the full breakdown of the current pick at the store and check the latest price before you commit.

What Else Shares the Drill Platform

Because these tools run on the same battery system, the smart move is to build a kit around one platform instead of buying every tool brand separately. Alongside the dewalt hammer drill, the same battery gives you a grinder tool for cutting and grinding metal, a portable pressure washer for cleaning jobs, and a battery powered pressure washer if you want a cordless option for the driveway.

The same applies to fastening. An electric screwdriver handles light assembly where an impact tool is overkill, the torque driver adds precision for delicate work, and the impact tool covers everything in between. One battery system, four jobs, no second charger on the shelf.

How to Use a Dewalt Hammer Drill on Concrete

The most common buyer mistake is grabbing a cheap bit and pushing hard. Concrete drilling is about using the right accessory and letting the tool work.

Start with masonry-rated bits, pull the trigger to the hammer setting, and let the bit find its rhythm before you add pressure. Use light to moderate forward force; pressing too hard stalls the hammer action and wears the bit faster. For holes deeper than a few inches, back the bit out periodically to clear dust and keep it cool. Finally, switch back to the standard drill setting for anything with a pilot hole that does not need hammering, so you do not chew up wood bits.

If you are working on a project that needs a straight or level line first, a laser level saves you from re-drilling, and for outdoor cleanup after the job, a small leaf blower clears the dust fast.

So Which One Do You Actually Need?

Run this quick filter before you spend money. If your projects involve concrete, brick, or masonry in any form, get the dewalt hammer drill first; it is the only drill in the pair that handles those materials. If your work is purely wood fastening, automotive bolts, or general assembly, skip the hammer drill and pick up the 1 2 impact tool, which will drive faster and more comfortably.

Most skilled DIYers end up with both eventually, since they are complementary rather than competing tools. If you are buying one now, buy for your concrete drilling first, then add the impact tool for fastening later once you confirm the workload is there.

Questions

Can a dewalt hammer drill drive screws?

Yes, but it is slower and less comfortable than an impact tool. The hammer action is mild on the drilling setting, so you can switch it off and drive screws, but a dedicated impact tool or electric screwdriver does faster, cleaner work.

What dewalt hammer drill bits do I need for concrete?

Use masonry-rated carbide bits, not standard wood or metal bits. Concrete drilling destroys regular bits quickly because the hammer action shatters their cutting edge.

Is a corded or cordless dewalt hammer drill better for concrete?

Corded models sustain long drilling runs without battery sag, so they suit dedicated masonry work. A cordless 20v brushless model is more portable and fine for occasional anchor holes and light block drilling.

Do I need both a hammer drill and an impact tool?

Only if you regularly drill masonry and drive fasteners. One project type usually dominates, so most buyers should pick the tool that matches their most common job and add the other later.

Can a hammer drill replace an impact driver for removing stuck bolts?

No. Rotational impact torque breaks loose seized fasteners, which a hammer drill cannot deliver. Use a 1 2 impact tool or a torque driver for bolt removal.

What is the cheapest way to buy a dewalt hammer drill?

Check the store coupon page for the current discount before checkout, since the code applies to the whole order and drops the price on the drill and any bundle you pair it with.
