Using a drill comes down to three things: choosing the right bit, dialing in the right settings, and letting the tool do the work instead of forcing it. Whether you’re hanging a shelf or building a deck, the basics are the same. Here’s everything you need to get started confidently.
Know the Parts of Your Drill
Before you pull the trigger, take a quick look at the key controls. The chuck is the clamp at the front that holds the drill bit. The collar is the numbered ring just behind it, which controls the clutch (more on that below). Most drills also have a speed selector switch on top, a forward/reverse toggle near the trigger, and a battery pack on the bottom.
If your drill has two gear settings, gear 1 gives you low speed with high torque, which is best for driving screws. Gear 2 gives you high speed with lower torque, which is what you want for drilling holes. Picking the right gear before you start makes a noticeable difference in control and results.
How to Insert a Drill Bit
Most modern drills use a keyless chuck, meaning you tighten it by hand rather than with a separate key. Point the drill away from you. Turn the chuck clockwise to loosen the jaws until your bit fits between them. Then turn the chuck counterclockwise until the jaws grip the bit’s shaft. You’ll feel a ratcheting mechanism click in. Keep tightening for 8 to 10 clicks to lock the bit securely.
A faster method, once you’re comfortable: put the drill in reverse, hold the chuck, and lightly tap the trigger to open the jaws. Insert the bit, switch to forward, hold the bit in place, and feather the trigger until the jaws grip. Then hand-tighten the ratchet.
If a bit slips or falls out during use, the chuck probably isn’t tight enough. Give that ratchet an extra firm twist by hand. Also make sure at least half an inch of the bit’s shaft sits inside the jaws so they have enough surface to grip.
Choosing the Right Bit
The bit you pick depends entirely on the material you’re drilling into. For general-purpose work in wood, metal, or plastic, standard twist bits are the go-to. Versions with a 135-degree split point grip the surface better and reduce wandering when you start the hole. Brad point bits have a sharp center spur that keeps them perfectly aligned, which makes them ideal when you need clean, precise holes in wood without splintering.
For larger holes in wood (like running a wire through a stud), spade bits cut fast. For concrete, brick, or stone, you need masonry bits, which have a tungsten carbide tip designed to pulverize hard material. Their deep flutes channel dust out of the hole so it doesn’t clog. Using a regular twist bit on concrete will burn out the bit and possibly damage your drill.
What the Numbers on the Clutch Ring Mean
The numbered collar near the chuck is the clutch, and it controls how much twisting force the drill delivers before it stops. When you set it to a low number, the clutch disengages quickly, limiting torque. At a higher number, the drill pushes harder before it slips.
This matters most when driving screws. Without the clutch, it’s easy to sink a screw too deep, split the wood, or strip the screw head (called cam-out). The clutch prevents all three by cutting power once the screw meets a set level of resistance.
The strategy is simple: start at a lower setting than you think you need, drive a test screw, and adjust upward until the screw sits exactly where you want it, flush or slightly below the surface. Once you find the right number, you can drive every remaining screw at that setting without thinking about it. For light-duty work like fastening thin wood or soft material, low settings work well. For larger screws in dense material, you’ll need to crank the number higher.
Past the highest number, you’ll usually see a drill icon. That setting disengages the clutch entirely, giving you full, unregulated torque. Use this position only when drilling holes, not when driving screws.
When to Use the Hammer Setting
Some drills have a hammer icon on the collar alongside the clutch numbers. This activates a rapid pulsing action: the bit rotates while also delivering short, fast hammer thrusts that break apart masonry. You need this setting when drilling into brick or lighter concrete. Pair it with a masonry bit.
For heavy concrete or stone, a standard drill’s hammer mode may not be powerful enough. That’s where a dedicated rotary hammer drill comes in. But for hanging things on a brick wall or drilling into mortar joints, the hammer setting on a regular drill handles the job.
Drilling a Hole Step by Step
Mark your spot with a pencil or a small indent (a nail tap works) so the bit has somewhere to seat. Set the drill to gear 2 for speed, turn the clutch to the drill-only position, and select forward rotation. Place the bit tip on your mark, hold the drill level and steady, and squeeze the trigger. Let the bit do the cutting. Pressing too hard causes the bit to bind, overheat, or wander off your mark.
For deeper holes, pull the bit out periodically to clear dust from the flutes. This is especially important in masonry, where debris builds up fast. If you need a specific depth, wrap a small piece of tape around the bit at your target depth as a visual guide.
Driving Screws Without Stripping Them
Switch to gear 1 for more torque at lower speed. Set the clutch to a low-to-medium number. Use a driver bit that matches your screw head exactly: Phillips, square drive, or star. A loose fit between the driver and screw head is the fastest route to a stripped screw.
If you’re working with wood, drilling a pilot hole first makes everything easier. A pilot hole is a smaller hole that guides the screw and prevents the wood from splitting. The right pilot hole size depends on the screw gauge and the wood type. For a common #8 screw, use a 1/8-inch bit in hardwood or a 7/64-inch bit in softwood. For a #10 screw, use 9/64-inch in hardwood or 1/8-inch in softwood. Hardwood always needs a slightly larger pilot hole because it’s less forgiving.
Staying Safe
Wear safety glasses every time. Drilling throws tiny chips of wood, metal, or concrete directly toward your face. When drilling masonry, add a dust mask because the powder is harmful to breathe. Gloves help with grip and protect your hands from sharp metal shavings.
Clamp your workpiece down whenever possible so both hands are free to control the drill. Loose material can spin or kick, and trying to hold something steady with one hand while drilling with the other is a recipe for injury. Keep loose clothing, drawstrings, and jewelry away from the spinning chuck. Tie back long hair.
Disconnect the battery or unplug the drill before changing bits. Don’t carry a drill with your finger on the trigger. And if the bit binds in the material and the drill jerks, let go of the trigger immediately rather than fighting it.
Brushed vs. Brushless Drills
If you’re shopping for a drill or trying to understand the one you have, the motor type affects performance and longevity. Brushed motors use physical contact points (carbon brushes) that create friction and heat. They work fine for occasional use, but the brushes wear out and need replacement roughly every 50 to 60 hours of use. Total motor lifespan is around 1,500 hours.
Brushless motors eliminate that friction entirely. They run cooler, convert 85 to 90 percent of battery power into work, and last dramatically longer, in the range of 20,000 to 25,000 hours. They also extend battery runtime by up to 50 percent per charge since less energy is wasted as heat. Brushless drills cost more upfront, but for anyone using a drill regularly, the longer battery life and near-zero maintenance pay for themselves.
Taking Care of Your Battery
Lithium-ion batteries, which power virtually all cordless drills today, are sensitive to temperature extremes. Charge them only between 32°F and 113°F. The sweet spot is 50°F to 104°F, where the battery chemistry works most efficiently. Never charge a battery that’s hot from heavy use; let it cool down first.
For storage, keep batteries indoors at room temperature, ideally between 59°F and 77°F. A drawer or closet works perfectly. Avoid leaving batteries in a hot car, near a radiator, or on a sunny windowsill. Extreme heat degrades lithium-ion cells permanently, reducing both capacity and lifespan in ways you can’t reverse.
