Most people buy a drill once and figure it out as they go. That works — until they strip a screw, crack a tile, or burn out a bit trying to drive into concrete with the wrong tool.
A drill is not a single tool. It’s a category with half a dozen distinct types, each built for specific materials and tasks. Picking the right one changes how fast you work, how clean the result looks, and how long your bits last.
Drill Types at a Glance
| Tool | Best for | Key limitation |
|---|---|---|
| Drill/driver | General drilling and controlled screwdriving | Not ideal for repeated masonry work |
| Impact driver | Long screws, lag screws, stubborn fasteners | Less precise for ordinary drilling |
| Hammer drill | Occasional holes in brick, block, and light concrete | Slower and less efficient than a rotary hammer in hard concrete |
| Rotary hammer | Frequent concrete drilling and light chiseling | Heavier, costlier, uses SDS tooling |
| Right-angle drill | Tight spaces between framing, cabinets, plumbing | Specialty tool |
| Drill press | Repeatable, perpendicular holes in shop work | Stationary, not for jobsite mobility |
Quick choice: for most homeowners, a cordless drill/driver is the best first drill. Add an impact driver for heavy fastening, a hammer drill for occasional masonry, or a rotary hammer for frequent concrete work.
What Makes Drills Different From Each Other
The word “drill” covers everything from a $30 corded model to a $400 rotary hammer. The differences aren’t just price — they’re mechanical. Understanding the core distinctions saves you from buying a tool that frustrates you on day one.
Chuck and Bit Interface
Every drill accepts bits through a chuck — the clamping mechanism at the front. Keyless chucks let you swap bits by hand in seconds. Keyed chucks require a small wrench but hold bits more securely under heavy load. For most homeowners, keyless is the right choice. For sustained heavy drilling, keyed chucks reduce bit slippage.
Chuck size determines which bits fit. A 3/8-inch chuck handles the vast majority of household tasks. A 1/2-inch chuck accepts larger bits and delivers more torque — standard on hammer drills and rotary hammers.
Torque and Clutch Settings
Torque is the rotational force the drill applies to the fastener or bit. More torque isn’t always better — driving a small screw with maximum torque strips the head or sinks it too deep.
The clutch — the numbered ring behind the chuck on most drills — limits torque at a set threshold. When resistance exceeds the setting, the clutch disengages and the chuck stops turning. This protects screws, materials, and the drill itself. Most drills offer 16 to 24 clutch settings plus a drill mode that bypasses the clutch entirely for boring holes.
One thing most beginners miss: clutch settings are relative, not absolute. Setting 10 on a 20V brushless drill delivers more torque than setting 10 on a 12V drill. Start low, test on scrap material, and adjust up.
Power Source
Corded drills deliver consistent power without battery management. For long sessions or sustained heavy use, corded tools don’t slow down as voltage drops. The tradeoff is mobility — a cord limits where you can work.
Cordless drills dominate the market for good reason. Modern 18V and 20V lithium-ion batteries deliver performance that matched corded tools for most tasks five years ago and surpassed them for many tasks today. Runtime on a 5.0Ah pack runs 45 to 90 minutes depending on load.
The voltage number on cordless tools is nominal, not actual. An 18V tool and a 20V tool from different brands often use the same battery chemistry — the difference is how manufacturers measure peak versus nominal voltage.
The Main Types of Drills and What Each One Is For
Drill/Driver
The standard cordless drill. It rotates a bit to drive screws and bore holes. If this is your first drill, our cordless drill beginner guide covers setup, chuck use, speed, and clutch control. The clutch controls torque for driving; drill mode bypasses it for boring. This tool handles 80% of what most homeowners need — assembling furniture, hanging shelves, drilling through wood and drywall, driving deck screws.
A drill/driver’s practical hole capacity depends on the exact model, bit type, material, speed, and manufacturer rating. Use the tool manual for maximum bit diameters rather than assuming one universal wood or metal limit.
Impact Driver
An impact driver looks similar to a drill/driver but works differently. Instead of pure rotational force, it delivers rapid rotational impacts — roughly 3,000 impacts per minute combined with rotation. This hammering action breaks loose stubborn fasteners and drives long screws through dense material without the cam-out that strips screw heads.
Impact drivers use a 1/4-inch hex collet, so they need compatible hex-shank accessories. They can drill with impact-rated hex bits, but a drill/driver gives smoother control and accepts a much wider range of ordinary drill bits. Where they excel: long structural screws, lag bolts, and any application where a regular drill bogs down or strips fasteners.
The noise is significant — impact drivers are loud. In enclosed spaces, hearing protection is worth using. See our impact driver vs drill comparison for a detailed breakdown of when to use each.
Hammer Drill
A hammer drill adds a percussive in-and-out motion to standard rotation — the bit hammers into the material while spinning. This combination breaks up masonry as the bit advances, making it the right tool for drilling into brick, concrete block, and stone.
Hammer drills are rated in blows per minute (BPM). A quality hammer drill delivers 30,000 to 48,000 BPM. The hammering action is engaged by a switch — in drill mode, it functions as a standard drill/driver.
For occasional masonry work, such as small anchor holes in brick or block, a hammer drill is often the practical choice. Wear eye protection, control dust, verify there are no hidden utilities, and follow the tool and bit manufacturer’s instructions.
Rotary Hammer
A rotary hammer uses a pneumatic hammering mechanism instead of the mechanical cam system in a hammer drill. The piston-driven impact is dramatically more powerful — a rotary hammer delivers 3 to 8 joules of impact energy compared to less than 1 joule for a hammer drill.
This matters when drilling holes larger than 1/2 inch in concrete, breaking up tile or light masonry with a chisel bit, or working in reinforced concrete. Rotary hammers use SDS-Plus or SDS-Max bits — the shank locks into the chuck rather than being clamped, allowing the bit to slide slightly during hammering.
A hammer drill can handle many occasional small masonry holes, while a rotary hammer is usually more efficient for frequent work, harder concrete, larger diameters, or chiseling. The break point depends on the specific tool and bit ratings, so check the manufacturer’s capacity chart. Read more in our rotary hammer guide.
Right Angle Drill
A right angle drill positions the chuck at 90 degrees to the motor body. This lets you drill in spaces where a standard drill won’t physically fit — inside cabinet frames, between joists, in tight corners behind pipes.
Most electricians and plumbers own one. For general homeowners, it’s a specialty tool worth renting rather than buying unless the need comes up regularly.
Drill Press
A drill press mounts the drill mechanism in a fixed column above a work table. The bit travels straight down on a consistent axis — something impossible to guarantee with a handheld drill.
This matters for woodworking joints, metalworking, and any application requiring precise hole placement and perpendicular entry. A benchtop drill press handles most hobbyist and home shop needs. Speed is adjustable on most drill presses by changing belt position — lower speeds for large bits and hard materials, higher speeds for small bits and soft materials. See our drill press vs hand drill comparison for more detail.
Which Drill Should You Use? Quick Decision Guide
- Mostly holes + normal screws: drill/driver.
- Long screws, structural fasteners, repetitive fastening: impact driver.
- Occasional brick/block/concrete holes: hammer drill with the correct masonry bit.
- Frequent or larger concrete holes / chiseling: rotary hammer.
- Tight framing or cabinet spaces: right-angle drill.
- Repeatable perpendicular shop holes: drill press.
How to Choose the Right Drill
Start With the Material
Wood and drywall — a drill/driver handles most common tasks. For drywall-specific hole technique and anchor prep, see how to drill into drywall.
Screws into wood — drill/driver for most, impact driver for long or structural screws.
Brick, block, mortar — hammer drill for holes up to 1/2 inch, rotary hammer for anything larger or more frequent.
Reinforced concrete, heavy demolition — rotary hammer only. Precision holes requiring exact placement — drill press.
Voltage and Battery Platform
For most homeowners, 18V or 20V is the right voltage. It’s enough for everything except sustained heavy rotary hammer work, and the batteries are widely available.
If you already own tools from one brand, stay in that ecosystem. Batteries from DeWalt, Milwaukee, Makita, and Ryobi are not interchangeable between brands, but they work across all tools within the same brand’s line. Buying a second drill in the same platform means you already have compatible batteries.
12V tools are worth considering for light tasks — driving cabinet screws, assembling flat-pack furniture, hanging pictures. They’re smaller, lighter, and easier to use in tight spaces. The tradeoff is less torque for demanding applications.
Brushed vs. Brushless Motor
Brushed motors use carbon brushes to transfer current to the motor’s rotating part. They work fine but generate friction and heat, which wears the brushes over time and reduces efficiency.
Brushless motors eliminate the brushes entirely — current is transferred electronically. The result can be better efficiency, less brush maintenance, and improved runtime or performance, but the actual difference varies by tool design, battery, and workload.
For occasional use, brushed drills are perfectly adequate and cost less. For regular use — anything beyond occasional weekend projects — brushless motors pay for themselves in battery life and longevity. Our brushless vs brushed motor guide covers this in depth.
Features That Matter When Buying a Drill
- Chuck size and type: determines which bits fit and how quickly you can change them.
- Two-speed gearbox: low speed gives control and torque; high speed helps with smaller drilling tasks.
- Adjustable clutch: helps prevent stripped screws and overdriving.
- Brushless motor: useful for frequent work, but not mandatory for occasional DIY.
- Battery ecosystem: often matters more than a small difference in advertised specs because batteries and chargers are a long-term cost.
- Ergonomics: balance, grip, weight, and trigger control affect real-world usability.
Drill Bits: What Goes in the Chuck Matters
The drill is only as good as the bit in it. Using the wrong bit type for the material is one of the most common reasons bits fail prematurely.
For a broader overview before choosing a specific bit, see our types of drill bits guide.
Twist bits handle wood, plastic, and metal. High-speed steel (HSS) works for most applications. Cobalt bits handle stainless steel and hardened metals. Titanium-coated bits stay sharp longer in wood and soft metals but the coating wears off — they’re not indefinitely superior to standard HSS.
Masonry bits have a carbide tip brazed onto a steel shaft. They’re designed specifically for hammer drilling into concrete, brick, and stone. Using a masonry bit in a standard drill without hammer mode works in soft brick but is inefficient and hard on the bit.
Spade bits bore large holes in wood quickly — 3/4 inch to 1-1/2 inch. They’re fast and cheap but leave rough edges. For clean holes, a Forstner bit produces far better results.
SDS bits are for rotary hammers only. The shank design locks into SDS chucks and allows the hammering motion without loosening. See our complete drill bit guide for a full breakdown by material.
Silica Dust and Masonry Drilling
Drilling concrete, brick, mortar, or stone can create respirable silica dust. Use dust-control methods appropriate to the task—such as on-tool extraction or a compatible shroud/vacuum setup—and follow the tool, bit, and workplace safety guidance that applies to your job. Eye and hearing protection are also important during hammer drilling and rotary-hammer work.
Maintenance That Extends Tool Life
Drills are low-maintenance tools, but a few habits make a difference.
Keep the chuck clean. Dust and debris in the chuck mechanism causes bits to seat unevenly and slip under load. A blast of compressed air after dusty work prevents buildup.
For long-term lithium-ion storage, follow the battery manufacturer’s guidance on charge level, temperature, and inspection intervals. Avoid storing packs fully depleted, exposed to high heat, or in damaged condition. Our cordless drill battery life guide covers storage and runtime tips in detail.
Replace worn bits before they damage work. A dull bit requires more pressure, generates more heat, and produces rougher holes. The cost of a new bit is always less than the cost of repairing damaged material.
What Most People Get Wrong
Buying more drill than they need is common — but so is the opposite. A homeowner who plans to mount a TV, build a deck, and occasionally drill into brick needs at least a hammer drill, not just a basic drill/driver.
Using the wrong speed for the material is the second most common mistake. Drilling metal requires slower speeds than wood — 300 to 1,000 RPM for most metals versus 1,500 to 3,000 RPM for wood. High speed in metal generates heat that dulls bits fast.
Skipping pilot holes in hardwood and near edges is the third. Pilot holes prevent splitting, reduce driving force needed, and produce cleaner results. In hardwood, they’re not optional — they’re the difference between a clean result and a cracked board.
Choosing With Confidence
Match the drill to the material and the frequency of use. A quality 18V brushless drill/driver handles most homeowner tasks. Add a hammer drill if masonry work comes up regularly. Add an impact driver if you’re driving a lot of long screws or working with structural fasteners.
The best drill is the one you’ll actually reach for when the job comes up — reliable, appropriately powered, and part of a battery platform you’ll expand over time.
