How to Choose a Drill in 2026: Buyer's Guide

How to Choose a Drill Buying Guide

A drill is the most fundamental power tool in any toolkit — and also one of the easiest to buy wrong. Voltage numbers dominate marketing but tell an incomplete story. The right drill depends on what you're actually drilling, how often, and whether you want to stay in a specific battery ecosystem. This guide explains what the specs actually mean and how to find the right drill without overspending.

Types of Drills and What They're For

Drill/drivers are the standard all-purpose tool — they drill holes and drive screws with a clutch that prevents overtightening. They handle wood, drywall, and light metalwork. They're the right choice for 90% of homeowners and most DIY users. See our best drills for beginners guide for top recommendations.

Hammer drills add a rapid forward-backward hammering action to standard drilling, which is necessary for masonry and concrete. If you're drilling into brick, concrete blocks, or stone, a hammer drill (or combination drill/driver/hammer) is required. A standard drill/driver will overheat and stall. See our best hammer drills guide for masonry-focused picks.

Impact drivers look similar to drills but use concussive rotational force to drive screws and bolts with far less user wrist torque. They excel at long screw driving (decking, framing), lag bolts, and automotive work. They're not ideal for drilling precision holes — the impact mechanism makes them harder to control for finesse work. Many professionals own both a drill/driver and an impact driver, often from the same battery platform.

Drill presses are benchtop or floor-standing tools for precision hole drilling at fixed angles. For furniture making, metalworking, or any application requiring perfectly perpendicular holes, a drill press outperforms handheld. See best drill presses for stationary options.

Voltage: What 12V vs. 18V vs. 20V Actually Means

Higher voltage means more potential torque — the rotational force that drives screws into hard materials and pushes bits through thick lumber. 12V drills are lighter (under 3 lbs) and more compact — they're sufficient for light homeowner tasks, cabinet installation, and furniture assembly. If your drill lives in a tool bag and you fatigue after extended use overhead, 12V is worth considering.

18V/20V (these are the same — brands use different measurement conventions) is the standard for general professional and serious DIY use. They handle all wood drilling, concrete with a hammer function, and full-day professional use without performance limits. Most professional tradespeople use 18/20V. For the best drills under $100, 20V platforms offer the best performance value. Also see DEWALT vs Milwaukee for platform comparisons.

Note on "max volts" vs. "nominal volts": A DEWALT "20V MAX" battery is actually 18V nominal. Makita's 18V and DEWALT's 20V MAX are functionally equivalent. Don't compare voltage numbers across brands without checking which measurement convention each uses.

Torque, Clutch Settings, and Chuck Size

Torque (measured in inch-lbs or Newton-meters) determines how much resistance a drill can overcome when driving fasteners. 400–500 in-lbs is adequate for most homeowner tasks. 700–800+ in-lbs handles professional framing and heavy fastener work. More torque is generally better, but higher-torque drills are heavier.

The clutch has numbered settings (typically 1–20+) that set the maximum torque before the clutch disengages to prevent overtightening. Lower numbers are for small screws and delicate materials; higher numbers are for heavy fastening. A drill mode (bypass clutch) is used for hole drilling. Beginners frequently drive screws past flush because they're using drill mode instead of an appropriate clutch setting — always use the clutch for screw driving.

Chuck size: most cordless drills use a 1/2-inch chuck (handles drill bits up to 1/2-inch shank). Some compact drills use 3/8-inch chucks, which limits bit size. For standard homeowner use, either works. For large-diameter hole saws or Forstner bits, a 1/2-inch chuck is required.

Battery Platforms: The Ecosystem Decision

Buying a drill means choosing a battery platform — and all future tools in that platform use the same batteries. DEWALT (20V MAX), Milwaukee (M18), Makita (18V LXT), and Ryobi (ONE+) are the four major ecosystems. The battery and charger are often more expensive than the tool itself, so switching platforms later is costly.

If you already own tools from one platform, stay in that ecosystem. If starting fresh: DEWALT and Milwaukee are the professional standards with the widest tool selection. Ryobi has the best value at consumer price points and the largest tool catalog (175+ tools). For professional tradespeople, see best DEWALT drills and best Makita drills. For homeowners, Ryobi offers excellent value — see best Ryobi drills.

Battery Ah (amp-hours): higher Ah means longer runtime per charge. A 2.0Ah battery runs about half as long as a 4.0Ah battery on the same tool. For occasional use, a 2.0Ah battery is fine. For all-day professional use, 4.0Ah–6.0Ah batteries are standard.
