This guide will break down everything you need to know to find the perfect cordless drill for your needs, making your projects smoother and more enjoyable. Let’s walk through each step with real examples.
What Makes a Cordless Drill “The Best”?
When we talk about the “best” cordless drill, it’s not a one-size-fits-all answer. The ideal drill for a professional carpenter will likely be different from the one for a weekend DIY enthusiast. However, several key factors consistently determine a drill’s performance, usability, and overall value. Understanding these elements will empower you to make an informed decision.
Power and Performance: Voltage and Torque
The power of a cordless drill is primarily determined by its voltage and torque.
Voltage (V): This indicates the power of the battery that runs the drill. Common voltages range from 12V to 20V, with some heavy-duty models going up to 36V or 40V.
12V Drills: These are typically smaller, lighter, and more compact. They are excellent for light-duty tasks like assembling furniture, hanging pictures, or drilling small holes in softer materials. They offer good maneuverability but may struggle with tougher jobs.
18V/20V Drills: This is the sweet spot for most users. They provide a great balance of power, battery life, and weight. They can handle a wide range of tasks, from drilling into wood and metal to driving larger screws. Most major brands offer excellent 20V platforms.
36V/40V Drills: These are beasts, designed for serious professional use or demanding DIY projects. They offer maximum power and runtime but are heavier and more expensive.
Torque (Nm or in-lbs): Torque is the rotational force a drill can deliver. It’s crucial for driving screws, especially into hard materials, and for drilling larger holes. Higher torque generally means more power.
Look for drills with variable speed settings. This allows you to control the rotation speed, which is essential for different tasks. Slower speeds are better for driving screws to prevent stripping, while higher speeds are good for drilling holes.
Many drills also have a clutch setting. This feature allows you to set a maximum torque limit, preventing over-driving screws and damaging your material.
Motor Type: Brushed vs. Brushless
This is a critical distinction that significantly impacts a drill’s performance and longevity.
Brushed Motors: These are the traditional type of motors found in many power tools. They use carbon brushes to conduct electricity to the motor’s armature.
Pros: Generally less expensive.
Cons: Less efficient, generate more heat, wear out faster (brushes need eventual replacement), and offer less power for their size.
Brushless Motors: These motors use electronic controls instead of physical brushes.
Pros: More efficient (meaning longer battery life), generate less heat, last longer, deliver more power for their size, and are generally more compact and lighter.
Cons: Typically found in higher-end, more expensive drills.
For the best overall performance, durability, and battery efficiency, a brushless motor is highly recommended. Many of the “best” cordless drills on the market today feature brushless technology.
Battery Technology: Ah and Voltage
The battery is the heart of your cordless drill. Understanding battery specifications is key to ensuring you have enough power and runtime for your projects.
Amp-hours (Ah): This measures the battery’s capacity – how much energy it can store. A higher Ah rating means the battery can power the drill for a longer period before needing a recharge.
Common sizes range from 1.5Ah to 5.0Ah or even higher.
For a 20V drill, a 2.0Ah battery is often standard and sufficient for most home tasks. If you frequently tackle larger projects or need extended runtime, consider a higher Ah battery.
Battery Chemistry: Most cordless tools today use Lithium-ion (Li-ion) batteries.
Pros: Lightweight, hold a charge well, and don’t suffer from the “memory effect” that older battery types did.
Cons: Can be sensitive to extreme temperatures.
When buying a drill, consider if it comes as a “bare tool” (just the drill) or a “kit” (drill, battery, and charger). Kits are usually more cost-effective if you don’t already own batteries for that brand’s platform.
Ergonomics and Features
Beyond power and battery, how the drill feels and the extra features it offers can greatly enhance your experience.
Grip and Balance: A comfortable, non-slip grip is essential, especially during extended use. The drill’s balance also affects how it feels in your hand. Many drills have ergonomic designs to reduce fatigue.
Weight: Consider the overall weight, especially if you’ll be working overhead or for long periods. Lighter drills are easier to maneuver.
Chuck Type: Most modern drills have a keyless chuck, which allows you to tighten and loosen the drill bit by hand. This is far more convenient than older keyed chucks. Look for a chuck size of 1/2 inch, as this is standard and accepts a wider range of drill bits.
LED Light: An integrated LED light that illuminates the work area is a small but incredibly useful feature, especially in dimly lit spaces. Many have a “delay off” function, so the light stays on for a few seconds after you release the trigger.
Variable Speed Trigger: As mentioned earlier, this allows for precise control over drilling speed and screw driving.
Forward/Reverse Switch: Essential for driving screws in and out. Ensure it’s easy to access and operate with one hand.
Belt Clip: A handy feature for keeping the drill accessible when not in use.

Frequently Asked Questions (FAQs)
Q1: What is the difference between a drill and a hammer drill?
A: A standard drill is designed for rotating to drill holes or drive screws. A hammer drill adds a forward-pulsing (hammering) action that assists in drilling into hard materials like concrete or masonry. For general home use, a standard drill is usually sufficient, but a hammer drill offers more versatility if you plan on working with masonry.
Q2: How long should a cordless drill battery last?
A: The runtime of a battery depends on its Ah rating and the intensity of the task. A 2.0Ah battery on a 20V drill might last for dozens of screws or several small holes on a single charge. For heavier work, a 4.0Ah or 5.0Ah battery will provide significantly longer runtime. All Li-ion batteries degrade over time and with use, but with proper care, they can last for many years.
Q3: Is a brushless drill worth the extra cost?
A: Yes, for most users, a brushless drill is a worthwhile investment. Brushless motors are more efficient, leading to longer battery life, and they offer more power and durability compared to brushed motors. They also tend to run cooler and last longer.
Q4: What does “20V MAX” mean?
A: “20V MAX” refers to the maximum voltage the battery reaches when fully charged. The nominal voltage, which is what it operates at most of the time, is typically lower (around 18V). This is a standard industry term used by brands like DeWalt.
Q5: Can I use batteries from different brands with my drill?
A: No, generally you cannot. Batteries are designed to be compatible only with tools from the same brand and often within the same voltage platform (e.g., a DeWalt 20V battery will only work with DeWalt 20V tools).
