Are Cordless Drills Any Good? The Definitive Answer for Beginners
The short answer is a resounding yes. Cordless drills have evolved dramatically. They now boast impressive power, long-lasting batteries, and a host of features that make them incredibly versatile and convenient for a vast array of tasks, from hanging a picture to building a deck.
Why the Question Even Arises: Corded vs. Cordless
For decades, corded drills were the undisputed champions of power and reliability. The idea of a battery-powered drill often conjured images of weak performance and short run times. This historical perception is why many people still question if cordless drills can truly compete.
However, technology doesn’t stand still. Battery technology, in particular, has seen revolutionary advancements. Lithium-ion (Li-ion) batteries have transformed the cordless tool market, offering:
Higher energy density: More power in a smaller, lighter package.
Faster charging: Less downtime waiting for your tool to be ready.
No memory effect: You can charge them anytime without harming their capacity.
Longer lifespan: They last for many charge cycles.
These improvements mean that today’s cordless drills can often match or even exceed the performance of many corded models, all while providing unparalleled freedom of movement.
What Makes a Cordless Drill “Good”? Key Features to Consider
When evaluating if a cordless drill is “good,” it’s helpful to understand the key features that contribute to its performance and usability.
1. Power (Voltage):
What it means: The voltage of the drill’s battery directly correlates to its power. Higher voltage generally means more torque (twisting force) and the ability to handle tougher jobs.
For beginners:
12V drills: Great for light-duty tasks like assembling furniture, hanging shelves, and drilling small holes in wood or drywall. They are typically lighter and more compact.
18V (or 20V MAX) drills: This is the sweet spot for most DIYers and many professionals. They offer a good balance of power, weight, and battery life for a wide range of applications, including drilling into harder materials and driving larger screws.
36V+ drills: These are the heavyweights, designed for demanding professional use, like drilling large holes in concrete or metal, or driving very large fasteners. They are usually heavier and more expensive.
2. Torque Settings (Clutch):
What it means: Most cordless drills have an adjustable clutch that allows you to control the amount of torque applied. This is crucial for preventing over-driving screws (stripping the head or damaging the material) and for drilling.
For beginners: Look for a drill with at least 15-20 torque settings. This provides enough control for delicate tasks and enough power for more robust ones. The “drill” setting bypasses the clutch for maximum power.
3. Chuck Type and Size:
What it means: The chuck is the part that holds the drill bit or screwdriver bit. Most modern cordless drills use a keyless chuck, meaning you can tighten and loosen it by hand. The size refers to the maximum shank diameter the chuck can accept.
For beginners: A 3/8-inch keyless chuck is standard and suitable for most common bits. A 1/2-inch chuck is more common on higher-voltage or hammer drills and allows for larger bits and better grip on hex-shank bits. Ensure it tightens securely.
4. Speed Settings:
What it means: Cordless drills typically have two speed settings, usually controlled by a switch on the tool.
Low speed (0-400 RPM): Ideal for driving screws, providing more control and torque.
High speed (0-1500+ RPM): Best for drilling holes, especially in softer materials.
For beginners: A variable speed trigger is essential. This allows you to precisely control the speed by how hard you squeeze the trigger, offering even more finesse.
5. Battery Type and Capacity:
What it means: As mentioned, Lithium-ion (Li-ion) is the standard. Capacity is measured in Amp-hours (Ah). A higher Ah rating means the battery can deliver power for a longer time on a single charge.
For beginners: For occasional use, a 1.5Ah or 2.0Ah battery might suffice. For more frequent or demanding use, consider 4.0Ah or 5.0Ah batteries for extended runtimes. Many kits come with two batteries, which is highly recommended so you always have a charged one ready.
6. Ergonomics and Weight:
What it means: How the drill feels in your hand, the grip comfort, and its overall weight are crucial for usability, especially during longer projects.
For beginners: Try to hold a drill before buying if possible. A well-balanced drill with a comfortable grip will reduce fatigue and make your work more enjoyable.
7. Brushless Motor Technology:
What it means: Many newer cordless drills feature brushless motors. These motors are more efficient, provide more power, run cooler, and last longer than traditional brushed motors.
For beginners: While often more expensive, brushless drills offer a noticeable performance upgrade and are a worthwhile investment if your budget allows and you plan on doing a lot of drilling or driving.
The Undeniable Advantages of Cordless Drills
The question “Are cordless drills any good?” is often best answered by looking at the tangible benefits they bring to the table.
Unmatched Portability: This is the most significant advantage. You can take your drill anywhere – up a ladder, into the garden, across the attic – without being tethered to an outlet. This freedom is invaluable for many tasks.
Safety: No power cord means no tripping hazard. This is particularly important in busy workshops or when working at heights.
Convenience: No need to find an extension cord or worry about the cord getting tangled or caught on obstacles. Just grab the drill and go.
Modern Performance: As we’ve discussed, modern cordless drills offer excellent power and torque, capable of handling a wide range of common household and DIY projects.
Versatility: With different bits and attachments, a cordless drill can be used for drilling holes, driving screws, sanding, polishing, and even mixing paint (with the right attachments).
When Might a Corded Drill Still Be Preferred?
While cordless drills are fantastic, there are a few niche situations where a corded drill might still have an edge:
Extremely Demanding, Continuous Use: If you’re running a drill press for hours on end or performing continuous heavy-duty demolition work where maximum, uninterrupted power is essential, a corded drill might offer more consistent performance without battery concerns.
Budget Constraints: Historically, corded drills were cheaper. While the gap has narrowed, you might still find a basic corded drill for a lower initial cost than a comparable cordless model.
Very Specific, High-Torque Applications: For certain industrial applications requiring sustained, extremely high torque, a corded tool might still be the primary choice.
However, for the vast majority of users, the benefits of cordless technology far outweigh these specific scenarios.
Real-World Scenarios: Putting Cordless Drills to the Test
Let’s imagine a few common projects and see how a good cordless drill shines:
Assembling Flat-Pack Furniture: A 12V or 18V drill with a clutch set to a low torque setting makes quick work of driving all those screws without stripping them. The portability means you can assemble it right where it needs to go.
Hanging Pictures and Shelves: Drilling pilot holes in drywall or even studs is effortless. The variable speed trigger allows for precise control, and the lack of a cord means you’re not bumping into furniture or walls.
Building a Small Deck or Fence: An 18V or 20V MAX drill with a higher Ah battery is perfect for driving long deck screws or lag bolts. The power is there, and you can move around the project site easily without dragging a cord.
Working in Tight or Awkward Spaces: Need to drill a hole under a sink or in a crawl space? A compact cordless drill gives you the maneuverability you need without the cord getting in the way.
