Best 20 Volt Lithium Small Cordless Drill Buying Guide

Power and Performance

The heart of any cordless drill is its motor and torque output. For small 20-volt lithium drills, look for models with brushless motors, they offer greater efficiency, longer runtime, and more consistent power delivery.

Torque ratings between 20 and 30 Nm are typical for light to medium drilling and driving tasks. If you plan to drill into harder materials like masonry or thick hardwood, consider a drill with a higher torque range or a two-speed gearbox.

For a deeper look at brushless options, see our dedicated guide to the best 20v brushless cordless drill for every job.

Most small drills in this category use brushed motors to keep costs low, but brushless variants are becoming more affordable. The trade-off is typically a slight increase in upfront price for better battery life and less maintenance.

Always check the maximum RPM (revolutions per minute) as well, higher speeds (1,500+ RPM) are better for fast drilling, while lower speeds (0, 400 RPM) provide more control for driving screws.

Battery and Runtime

Battery capacity is measured in ampere-hours (Ah). For compact 20-volt lithium drills, common capacities range from 1.3 Ah to 2.0 Ah. A higher Ah rating means longer runtime between charges, though it also adds weight.

Most kits include a charger that fully replenishes a battery in 3, 5 hours. Some models offer quick chargers that cut that time in half.

If you frequently work on larger projects, consider a drill that comes with two batteries so you can keep one charging while using the other. For more on battery technology, our best 18 volt lithium cordless drill guide covers similar considerations.

Lithium-ion batteries hold their charge well over time, but it’s wise to store them in a cool, dry place when not in use.

Some drills feature a fuel gauge on the battery to show remaining charge, which is a handy convenience. If you already own tools from a particular brand, sticking with the same battery platform can save money on future purchases.

Ergonomics and Weight

A small cordless drill should feel balanced in your hand, especially during extended use. Look for models weighing under 3.5 pounds (with battery) for comfortable overhead drilling or tight spaces. Rubberized grips reduce vibration and improve control.

Compact designs also allow you to reach into corners and between studs. For a roundup of the lightest options, check out our best small cordless drill for every project.

Weight distribution matters: a drill with the battery mounted at the base of the handle feels more natural than one with a bulky battery pack that makes it top-heavy.

Many manufacturers now offer slim-profile batteries that reduce overall bulk without sacrificing capacity. If you plan to use the drill for long periods, prioritize models with a comfortable grip and low vibration.

Chuck and Speed Settings

The chuck is the part that holds the drill bit. Most small 20-volt lithium drills feature a 3/8-inch keyless chuck, which allows you to change bits quickly without a separate key.

Some models offer a 1/2-inch chuck for larger bits, but that’s less common in compact drills. Variable speed triggers let you control the RPM by how hard you squeeze, giving you precise control for driving screws versus drilling.

A two-speed gearbox (typically low 0, 350 RPM for high torque, high 0, 1,500 RPM for speed) adds versatility. For a broader overview of drill features, see our best cordless drill for every project.

Some drills also include a clutch with multiple torque settings (often 15, 21 positions). This prevents overdriving screws and stripping heads. A higher number of clutch settings gives you finer control, especially when working with different materials like drywall, wood, or metal.

Additional Features

Modern cordless drills often come with extras that enhance usability. An integrated LED work light illuminates dark work areas, look for models with a light that stays on for a few seconds after releasing the trigger.

A belt clip is useful for keeping the drill within reach on a jobsite. Some kits include a storage bag or case, as well as a set of drill bits and screwdriver bits.

For heavy-duty applications, you might want a drill with a metal chuck and all-metal gears, as covered in our best heavy duty cordless drill for every jobsite.

Other handy features include a magnetic bit holder on the body, a battery charge indicator, and a soft-start function that prevents the bit from wandering when you first squeeze the trigger. While not essential, these conveniences can make a big difference in daily use.

Frequently Asked Questions

What is the best 20 volt lithium small cordless drill for beginners?

For beginners, we recommend the AVID POWER 20V Cordless Drill Set or the BLACK+DECKER BDCDD120C. Both are lightweight, easy to use, and come with essential accessories.

The AVID POWER is particularly budget-friendly, while the BLACK+DECKER offers a bit more power and a trusted brand name. Both have high BP Scores and positive user feedback.

How important is a brushless motor in a small cordless drill?

A brushless motor is more efficient than a brushed motor, providing longer runtime, more torque, and less heat buildup. It also requires less maintenance because there are no brushes to wear out.

For frequent or heavy use, a brushless drill is worth the extra cost. However, for occasional light tasks, a brushed motor drill is perfectly adequate and more affordable.

What torque setting should I look for in a 20V small drill?

For light tasks like assembling furniture or driving screws into drywall, a torque range of 15, 20 Nm is sufficient. If you plan to drill into wood or metal, look for at least 25, 30 Nm.

Many drills offer multiple clutch settings (e.g., 21+1) that let you dial in the exact torque to prevent overdriving. Higher torque also helps when drilling into harder materials.

Can I use these small drills for heavy-duty tasks?

Small 20-volt lithium cordless drills are designed for light to medium-duty work. For heavy-duty tasks like drilling into concrete or driving large lag bolts, you’ll need a more powerful drill or a dedicated impact driver.

If you frequently tackle demanding jobs, consider a heavy-duty model from our best heavy duty cordless drill guide or a combo kit that includes both a drill and an impact driver.

How long do the batteries last on a typical 20V lithium drill?

Battery life depends on the capacity (Ah) and the workload. A 1.3Ah battery might last 30, 45 minutes of continuous use, while a 2.0Ah battery can provide up to an hour.

For intermittent DIY tasks, a single battery often suffices for a full day of light work. If you have a larger project, having a second battery is helpful.

Always charge batteries fully before first use and store them at room temperature for optimal lifespan.
