Shoppers tend to treat the cord as the whole decision. Home Depot does not. On its Power Drills department the cord is one filter group among many, listed immediately after maximum speed in RPM, with all 278 tools in the department sitting underneath the whole rail together.
That is a useful place to start, because it tells you something the marketing copy will not: the retailer that sells both sides files them as one product class. What follows is a read of what Home Depot actually publishes about each side, which specs carry across the cord line, and which ones only ever describe a battery.
One department, one filter for the cord
The Power Drills listing runs 278 results. The filter rail that narrows them includes a group called Cordless/Corded with exactly two values, Cordless and Corded. Every other filter group applies to the whole 278 or to a subset defined by something other than the power source.
Those shared groups are the ones that describe drilling:
- Chuck Size, listed as 1/4 in., 3/8 in., 1/2 in. and 1-1/8 in.
- Chuck Type, listed as Keyless, Keyed and Hex
- Maximum Speed in RPM, banded as 0-999, 1000-1999, 2000-2999, 3000-3999 and 4000 plus
- Motor Type, listed as Brushed or Brushless
- Power Tool Features, including Keyless Chuck, Variable Speed, LED Light and Cushioned Grip
None of those five change meaning when you unplug the tool. A 3/8 in. keyless chuck holds the same bits at the same speed whichever way the current arrives.
How Home Depot writes the cordless drill vs corded drill distinction
The retailer keeps two separate drill guides, and neither one is a head-to-head. The first, How to Use a Drill, runs a parts list: chuck, trigger, clutch torque selector, forward/reverse/lock selector, and then one entry it calls Battery or cord. That entry reads, in full, that some drills are corded and plug into the wall while others have a rechargeable battery pack. One line. Every other part on that list is described once, for both.
The second guide, Best Cordless Drills for Your Projects, is where the numbers live, and it is cordless-only by title. It publishes the voltage range most drills fall in, 7.2 to 20 volts, and says 12-volt models suit general household use. It gives the most common battery rating as 18 volts, with the full span running from 4 volts to 28 volts for heavy-duty tools. It explains amp hours as battery capacity and states the trade directly: a 3.0Ah lithium-ion pack lasts twice as long as a 1.5Ah pack and weighs twice as much.

Which published specs survive the cord
Here is the same filter rail sorted by whether the spec describes the drill or the power source.
| Published spec | Applies to corded | What it actually measures |
|---|---|---|
| Chuck Size (1/4, 3/8, 1/2, 1-1/8 in.) | Yes | Largest bit shank the jaws accept |
| Chuck Type (keyless, keyed, hex) | Yes | How bits are changed |
| Maximum Speed (RPM bands) | Yes | Rotation rate at full trigger |
| Motor Type (brushed, brushless) | Yes | Friction, heat and service life |
| Clutch torque selector | Yes | Resistance at which the clutch slips |
| Battery Voltage (4V to 18V and up) | No | Energy output of the pack |
| Battery Amp Hours (1.3Ah to 2Ah and up) | No | Runtime, and weight |
| Battery Platform (brand systems) | No | Which other tools share the pack |
| Number of Batteries Included | No | Whether a spare ships in the box |
Five to four, and the four that fail are all one subject. Note also that both Included Battery and Battery Amp Hours carry a No Battery value. That is the facet corded tools fall into, and it is the clearest signal in the whole rail that the battery fields were built for one half of the department and left blank for the other.
Where the difference between cordless drill and corded drill stops being a spec
Once the battery fields are set aside, the remaining gap is not published as a number anywhere on the site. It is reach, and it is weight, and both are situational rather than specified.
Home Depot gestures at this in its own words. The cordless guide opens by saying the point of the tool is drilling and driving anywhere in or around your home without worrying about an extension cord or being near an outlet. That is a statement about where you stand, not about what the tool does to the wood. It then closes with advice that no spec sheet can replace: visit the store and hold the drills with batteries installed, because the quoted weight may not match how the tool balances in your hand.
The weight point is worth sitting with. A corded drill carries no pack at all. A cordless one carries a pack whose mass scales with the runtime you chose, by the retailer’s own 3.0Ah-versus-1.5Ah arithmetic. So the heaviest cordless drill in a lineup is usually the one someone picked for endurance, and the lightest drill in the department is often the one with a cord trailing off it.
What the comparison guide compares instead
Home Depot does publish a drill comparison. It is Impact Drivers vs. Drills, and it draws the line somewhere else entirely: a drill is an adjustable-speed tool with a keyed or keyless chuck, an impact driver is more compact, carries more torque and uses a quick-change clamp for hex-shank bits. The guide then splits projects between them. Hanging shelves, installing light fixtures, drilling metal or plastic and mounting artwork go to the drill. Decks, fences, lag bolts and stubborn rusted fasteners go to the driver.
It also handles brushed against brushless in plain terms: brushed motors cost less, give higher torque at low speeds and wear their brushes out sooner, so they suit occasional use; brushless motors run without that friction, so they bring more power, less heat and longer battery life for regular heavy use, at a higher price up front.
Both of those distinctions are published, and both are indifferent to the cord. You can buy a brushed corded drill, a brushless cordless drill, or either of the other two combinations.
How to use the published numbers
If you want the retailer’s own data to do the work, run it in this order:
- Set chuck size first. 1/4 in. is fixed on light-duty tools, 3/8 in. is the general-use size that fits the majority of bits, and 1/2 in. is the heavy-duty option.
- Set the RPM band next, using the published advice to run faster through wood and slower when driving screws.
- Choose brushed or brushless on how often the tool will be used, not on the cord.
- Only now apply the Cordless/Corded filter, because it is the one choice above that the other three do not constrain.
- If you land on cordless, read the battery platform field before the voltage, since the pack has to match whatever else you own or plan to own.
The full cordless drill guide is where those battery fields are explained, and our own look at power tools against hand tools covers the step before this one.
What is missing from the published record
Two gaps are worth naming. Home Depot keeps a Best Power Drill for Your Projects guide alongside the cordless one, and at the time of writing that page returned an error rather than its content, so the corded side has no guide of its own to quote. And nowhere in the filter rail is there an amperage field, which is the number a corded drill’s own box leads with. The retailer indexes the battery side thoroughly and the plug side barely at all.
That asymmetry is the honest finding here. It is not evidence that corded drills are worse. It is evidence that the catalog was built around battery platforms, which are what a tool brand wants you to commit to.

Frequently asked questions
Ques: Does Home Depot publish a direct cordless-versus-corded comparison?
No. Its drill comparison guide covers impact drivers against drills. The cord appears as a single line in the parts list of its how-to guide and as a two-value filter on the Power Drills department page.
Ques: Which specs should I compare across both types?
Chuck size, chuck type, maximum RPM, motor type and the clutch torque selector. All five are published for the whole department and none of them depend on the power source.
Ques: What does amp hours tell me that voltage does not?
Voltage is the energy output of the pack; amp hours is its capacity. The published rule of thumb is that a 3.0Ah pack runs twice as long as a 1.5Ah pack and weighs twice as much, so it is a runtime-against-weight choice rather than a power one.
Ques: Is a brushless motor only available on cordless drills?
No. Motor Type is a separate filter from Cordless/Corded in the same department, so the two choices are independent of each other.
