What Should I Look for in a Cordless Drill? Your Essential Buying Guide
So, you need a cordless drill. Whether you’re hanging a shelf, assembling furniture, or tackling a bigger DIY project, a good drill is your best friend. But with so many choices, what actually matters? This guide will walk you through the key features that separate a good drill from a great one, ensuring you make a smart purchase that will last.
Understanding the Basics: Power, Battery, and Comfort
Before we get into the fancy features, let’s cover the fundamentals. These are the core elements that will affect how your drill performs and how you feel using it.
Motor Power: The Heart of Your Drill
The motor is what makes the drill spin. For cordless drills, motor power is often measured in volts (V).
Voltage: Generally, higher voltage means more power.
12V Drills: These are smaller, lighter, and great for light-duty tasks like hanging pictures, assembling IKEA furniture, or drilling into drywall. They are easy to handle in tight spaces.
18V Drills: This is the sweet spot for most DIYers and homeowners. They offer a good balance of power for drilling into wood, metal, and even light masonry, along with decent battery life. They can handle a wider range of tasks.
20V Max Drills: Many brands label their 18V drills as “20V Max.” This refers to the peak voltage when the battery is fully charged, rather than the nominal voltage. For practical purposes, these are comparable to 18V drills.
36V+ Drills: These are typically for heavy-duty professional use, offering maximum power for demanding applications like drilling large holes or working with tough materials. Most homeowners won’t need this level of power.
Battery: The Lifeblood of Cordless Tools
A cordless drill is only as good as its battery. Here’s what to consider:
Battery Type:
Lithium-Ion (Li-ion): This is the standard for modern cordless tools. Li-ion batteries are lighter, hold a charge longer, and don’t suffer from the “memory effect” that older NiCad batteries did. They are the clear winner.
Nickel-Cadmium (NiCad): Older technology. They are heavier, lose their charge faster, and can be damaged if recharged before being fully depleted. Avoid these if possible.
Battery Capacity (Amp-Hours – Ah): This tells you how long the battery will last on a single charge.
1.5 Ah – 2.0 Ah: Good for lighter use or if you have multiple batteries.
3.0 Ah – 4.0 Ah: Offers a good balance of runtime and weight for most home projects.
5.0 Ah+: Provides extended runtime for longer jobs or demanding tasks.
Battery System: If you plan to buy other cordless tools from the same brand (like a saw or sander), check if they use the same battery platform. This can save you money in the long run, as you might only need to buy the tool bare (without a battery and charger). Many manufacturers offer excellent battery ecosystems.
Ergonomics and Comfort: How it Feels in Your Hand
You’ll be holding this drill, so comfort is crucial.
Grip: A comfortable, non-slip grip reduces fatigue and improves control. Look for rubberized or textured grips.
Weight and Balance: A drill that feels too heavy or is poorly balanced can make even simple tasks tiring. Try to hold a drill before you buy it if possible, or read reviews that specifically mention weight and balance.
Trigger Feel: A smooth, responsive trigger allows for better speed control.
Must-Have Features for Enhanced Performance and Convenience
Beyond the basics, certain features can significantly improve your drilling experience.
Keyless Chuck: The Standard for Quick Bit Changes
The chuck is the part that holds the drill bit.
Keyless Chuck: This is the most common type and allows you to tighten and loosen the bit by hand, without needing a separate chuck key. It’s much faster and more convenient. Most modern drills have them.
Chuck Size: Most drills come with a 1/2-inch (13mm) chuck, which can accommodate a wide range of bit sizes. Smaller 3/8-inch (10mm) chucks are usually found on very compact 12V drills.
Variable Speed Trigger: Precision Control
This feature allows you to control the drill’s speed by how hard you squeeze the trigger.
Why it’s important:
Starting holes: Begin drilling slowly to prevent the bit from wandering.
Driving screws: A slower speed gives you more control when driving screws, preventing over-driving or stripping the screw head.
Different materials: You can match the speed to the material you’re working with.
Clutch Settings: Protecting Your Work and Your Bits
The clutch is a ring with numbers around the chuck. It helps prevent over-driving screws and stripping screw heads.
How it works: When the clutch setting is reached, the drill will slip or stop rotating, even if you keep pulling the trigger.
Choosing a setting:
Lower numbers: For delicate tasks or small screws.
Higher numbers: For larger screws or driving into harder materials.
Drill setting (often marked with a drill bit icon): This bypasses the clutch for pure drilling.
LED Work Light: Illuminating Your Workspace
A built-in LED light, usually located around the chuck, is incredibly useful.
Benefits: It illuminates the drilling area, especially in dimly lit spaces or corners, helping you see exactly where you’re drilling or screwing. Many modern drills have a “delay” feature, meaning the light stays on for a few seconds after you release the trigger.
Brushless Motor vs. Brushed Motor: The Future of Power
This is a significant differentiator in modern drills.
Brushed Motor: The traditional type. It uses carbon brushes that wear down over time and require replacement. They are less efficient and generate more heat.
Brushless Motor: These motors use electronic controls instead of physical brushes.
Benefits:
More power and torque: They can deliver more force.
Longer runtime: More efficient, meaning your battery lasts longer.
Increased durability: No brushes to wear out, leading to a longer tool lifespan.
More compact designs: Can allow for smaller, lighter tools.
Consideration: Drills with brushless motors are often more expensive, but the benefits usually justify the cost for serious DIYers.
Impact Driving (Impact Drivers vs. Hammer Drills): Know the Difference
While we’re talking about drills, it’s worth noting related tools.
Standard Drill/Driver: Rotates to drill holes and drive screws.
Hammer Drill: Adds a “hammering” action (percussive blows) to the rotation. This is useful for drilling into masonry like brick or concrete. If you plan to do any drilling into hard walls, a hammer drill function is a must.
Impact Driver: This tool delivers high torque through rapid rotational impacts (like a quick hammering motion). It’s excellent for driving long screws or lag bolts quickly and efficiently without stripping the head. They are typically more compact than drills and have a different chuck system (hex shank). While a hammer drill can drive screws, an impact driver is designed for it.
Additional Features to Consider
These features add extra convenience and functionality.
Variable Speed Settings (Multiple Modes)
Some drills offer distinct speed settings (e.g., Speed 1 for high torque/low speed, Speed 2 for high speed/low torque). This is different from the variable speed trigger, which offers a continuous range. Having pre-set speed modes can make it easier to switch between tasks.
Built-in Level or Bubble Indicator
A small bubble level integrated into the drill body can help you ensure your holes are perfectly straight, especially when hanging shelves or pictures.
Belt Clip
A handy accessory for keeping your drill easily accessible when moving around a job site.
Tool Storage Case
A good carrying case protects your drill and accessories, making it easy to transport and store. Many brands offer stacking cases that integrate with their other tool storage systems.
