If you’re just embarking on your DIY journey, you just want one power drill that does all the jobs in the house. A power drill is basically a screw diver and is considered the most popular power drill of all time. It has a chuck which accepts a whole range of bits in different lengths and sizes, from circular bits to the hex-shaped drill bit. Brilliantly, when you put your hex-shank bit into the chuck and it will turn into a screwdriver.
As your DIY improves, you’d suddenly find that the power drill doesn’t give the power you need to drive on tougher material or you are frustrated for having to switch between drills of varying powers in order to complete a job. That’s where you’ll find a need for a different power tool. So, what’re your drilling priorities? This handy guide will guide you to find the best option for you to undertake a variety of DIY tasks and projects.

Lithium-ion Battery drill vs NiCad Battery Drill
We are comparing a Bosch 20 Volt and a DeWalt 20 Volt power drill. The former has a Lithium-ion battery whereas the latter has a NiCad battery. The DeWalt power drill is larger than the Bosch power drill because its battery is larger and heavier than that of the Bosch even though both have an 18 Volt battery.

Lithium-ion Battery Do Not Discharge When Not In Use
The advantages of Lithium Ion batteries over DeWitt batteries are obviously it is lighter and more compact, and it doesn’t feel taxing in your hand for prolonged use. When you charged a lithium-ion battery, it remained charged over time. The old-fashioned NiCad batteries, tend to discharge when not in use. 20V MAX Cordless Drill / Driver Kit, Compact, 1/2-Inch (DCD771C2) Shop at Walmart
When choosing how much power one require on a drill, generally you need an 18 Volt -20 Volt power battery to handle about any task in the house. A 12 Volt battery can only handle some light-duty work. Check the manufacturer’s specs as printed in the box before you made your purchase. Some manufacturers will claim it has a 20Volt max but it has an average of 18Volt battery. Generally, it is all the same. Test it and compare the power you feel in the palm of your hand.
Brushed Motor vs Brushless Motor
When choosing a power drill, consider one with a brushless motor. A brushless motor is considerably more costly. It cost about 50% more than the brushed motor. The main difference between the brushless and the brushed motor is how much resistance the motor has. There’s less resistance in the brushless motor than in the brushed motor. There’s a contact point in the brushed motor and this slowed down the speed a bit and destroy a bit of efficiency. The brushless motor is sometimes considered to be a smart motor in that they have chips inside that would help regulate power delivering power when needed and less when not needed.
It senses the amount of power it needs for the drilling task on hand and it delivers the right amount of power. A brushless motor is able to increase speed and power in its drilling and has a longer life.
The brushless motor is claimed to have 50% more run-time and definitely, the speed of the brushless motor wins hand down when compared to the brushed motor.
Torque And Speed In A Power Drill
You would have noticed in a power drill there is a torque and speed setting. Torque is the force that the drill is turning the bit. For example, if you want to drill a hole through metal. You need the power to drill the bit, so the torque has to be set high, and you would want the drill slowly so that you can control your drilling. If you are drilling in a wood, you don’t need much power, so a lower torque is sufficient. However, you would need a faster speed to drive in the bit.
Why Torque And Variable Speed Settings Are Important
The torque is set according to the type of drilling. If you are drilling through wood and if the torque is not high enough it will not totally drive the screw to flush with the surface of the wood. If the torque is set on high, it means it has more power, then the screw will be flushed on the surface of the wood. Speed plays a complementary role, for setting too high torque with low speed, it will not be powered through.
High torque with low speed will be the initial step to guide the screw. But once the screw is guided in, the speed has to be set high to drive it in. But be careful, too much speed and torque may bury the screw and split its head. That’s why having a power drill with a setting for a torque and variable speed setting is so beneficial.
Torque Control and Variable Clutch Setting
Just behind the chuck is the torque selection ring that provides the settings for the multi-level of torque. The torque is the twisting force that is needed to overcome the resistance and screw to the correct dept required. Word of caution here, if the torque setting is too over-powering for the job, the screw can be driven too deeply. This would result in losing control of your drill and accuracy causing irreparable damage to your work.
Power Drills vs Impact Drivers
We all know the function of a power drill. Yes, its main function is to drill holes and screws. An impact driver is perhaps an upgraded version of the common power drill.
A power drill and an impact driver share many similarities. They look alike and they can drive screws into vast different materials. Their similarities end here but the impact drivers make work much easier.
Impact Drivers Makes The Difference
Here’s the main difference between a power drill and an impact driver. An impact driver drives a screw or a bit using the same rotational motion a power drill use. But as you drive in the screw, the impact driver also uses a combination of hammering action downwards and sideways. The combination of drilling and hammering makes it easier to drive screws into tough materials. The hammering effect of downwards and sideways prevent the drive bit from slippering off the screw heads. This prevents the head from being stripped off or ruining the screw.
You can distinguish an impact driver by the loud noise it generates when it is drilling. The repetitive thud noise is the result of the hammering actions not found in a normal power drill. The noise increased in intensity depending on how fast you’re driving in the screw.
To prevent the drive bit from slipping, normally you have to apply pressure with a power drill. An impact driver’s hammering action together with its screwing action mostly prevents this to happen. Just apply enough pressure on the screw to keep it guided and on point.
Due to its hammering actions, an impact driver is an invaluable tool for removing stubborn bolts and screws by reversing the spin. It also is great for removing fasteners that are over-torqued and corroded.

Limitation Of A Impact Driver
An impact driver can’t do precise drilling like a small pilot hole in wood – your power drill will do a better job since you don’t need a thumping hammering action when doing easy drilling. The thumping actions might bust the hole and pierce it.
The advantage of a power drill over the impact diver is that a power drill has a chuck that consists of claws which can open and close to accept a variety of drill bits for all many drill functions. An impact driver can have a quick-change sleeve but it can only accept ¼-inch hex shanks.
How Precise Is Power Drills Compared With Impact Driver?
Most power drills have two gears: one which has more torque is slower and is suitable for driving in screws, and the other gear has less torque and is faster for precise drilling holes. The impact driver has only one gear and has a bit of precision with use together with its variable speed.
Power drill has a clutch which prevents accidentally tightening a screw-down too much or blasting through the material. The clutch is like a built-in torque wrench in that you can set the required torque level so that when it reaches a certain torque level, it will stop the driver. Impact drivers which do not have clutches, it is easier to overdrive a bit. So if you’re using an impact driver, take special precautions when rending how much strength and precision the tool has.
Should I Use The Power Drill Or The Impact Driver?
A power drill is great for drilling and an impact driver is great for driving. You cannot choose one from another but they actually complement each other. What the power drill cannot accomplish, an impact driver can. If an impact driver lack of precision work, the power drill triumphs. Worry not, you don’t have to keep changing your tools in your work for manufacturers nowadays have come up with Power drill and Impact drill Combos, so that you can have the best of both worlds.
Hammer Drills vs. Impact drills
Those who are first introduced to hammer drills are confused about the difference between a hammer drill and an impact drill. In fact, there are differences in the method of operation, their purpose of use, appearance and weight.
Purpose Of Use
Hard knocks and drilling into a hard surface like a brick or concrete are the job of a hammer drill. Due to its versatility, some hammer drills can double up as a normal regular drill.
On the other end of the spectrum, an impact driver can only drive fasteners like screws and nails. It can also drill holes and drive nails through sheetrock and drywall if needed. Unable to control its extra power, an impact driver should never be used for fine and precise woodworking.
At first glance, you would able to distinguish a hammer drill from an impact driver. The hammer drill is physically bigger in size than an impact driver and is heavier. Of course, due to the masonry work, it can handle, the hammer drill is sometimes referred to as the small jackhammer.
In contrast, the impact driver is shorter and stubbier. It has a hexagonal socket instead of a chuck. As mentioned above, an impact driver can have a quick-change sleeve but it can only accept ¼-inch hex shanks.
With its larger size, a hammer drill certainly exerted more power than an impact driver. When it drives fast on hard material, you will feel the hammer drill vibrates back and forth with a loud thunderous noise. However, it has an adjustable clutch to prevent you from applying too much force.
An impact driver power-through in a rotary manner together with an up-down thumping motion. It can also be used as a screwdriver when less power is used. Most impact driver does not have an adjustable clutch to control their power in a more precise job, like putting in a screw. BLACK+DECKER Hammer Drill, 1/2-Inch, 6.0-Amp (DR670) Shop at Walmart

Cordless Drill Shopping Guide
To a DIY er or a professional, a cordless power drill is perhaps the most useful tool to have in your work. Obviously, it can drive screws and can drill holes. A perfect gift of a power drill will make your husband or father happy on his birthday and also on Father’s Day. The power tool is the symbol of power, and it is an essential tool that every home should have around to make simple home repairs rather than look in the directory to call for the service of a carpenter. Today, as more and more brick-and-mortar hardware stores are mushrooming everywhere to cater for DIY for their home improvement work, so do everything a DIY er need is available online for convenience and at a competitive price.
What A Cordless Power Drill Can Do
Your husband or your father will appreciate these power tools when they are needed to put holes and screws in wood or walls to hang a picture or paintings. You can tell whether it is a cordless drill, is when you fire up it without having a chord attach it to an electric source. During your unpacking, you’ll be greeted with 2 batteries pack and a charging dock. Select the right power drill to suit the type of woodworking and assembly.
Cordless power drills, today, are super-charged by a more efficient and rechargeable Lithium-ion battery. With advanced improvements, it allows the battery to be fully charged quicker, in less than an hour, and able to retain more power for longer. It also can use the same battery pack as other power tools from the same brand, thus reducing the cost of buying lots of batteries.
What Features Works Best For Me?
How much power you want in your cordless drill will largely depend on how much voltage it has. It ranges from 3 Volts to 48 Volts. The more powerful is the drill, the higher is its voltage, and also more costly. You can see the voltage of your tool from the label on its side, BLACK+DECKER 4-Volt MAX* Cordless Lithium-Ion Led Screwdriver, BDCS30C. Shop at Walmart

On heavy-duty jobs where it requires driving screws and drilling into harder materials, like metal and ceramic, select a cordless drill driver with a higher 14 V or more. BLACK+DECKER 20-Volt MAX Lithium 2 Speed Cordless Drill, BDCDD220C Shop at Walmart
The compact design, 30 per cent smaller than the GC1801 Drill/Driver Lightweight at 2.64 lbs provides less fatigue
Generally, a cordless power drill with a higher voltage capacity will weigh much more than a low-voltage one. Depending on how long you’re holding it in your hand when working on the tool, the longer you hold it, the more you would feel the strain in your wrist and arm.
Lower-voltage power drills cost less than high-power ones. You may consider saving money and buying a low-voltage power drill for simple light work but have you considered having problems in the future when trying to complete more heavy-duty tasks? You then have to buy another drill.
Most cordless power drills today have multiple uses. You can use the drill for a circular saw or as an impact driver. If you are just starting out and you need a drill with multiple functions, a cordless drill is a cheaper alternative.

Should You Buy A Corded Power Drill?
Between a noisy corded power drill and a sleek cordless drill, which one would you buy? Everything being equal, you would definitely choose a cordless tool. Your choice is obvious if mobility is what you are looking for. You can work anywhere, of course until your battery runs out. The corded species are cumbersome and are reliant on an extension cord for their power supply. Either you love it or you loathe it. A corded power drill also has its advantages.
With a 110-volt supply, the corded drill is more powerful than its closest cousin which runs at 12 to 18 Volts, or maybe a maximum of 20 Volts.
The power of the drill is not dependent on the maximum power output. Say our electricity supply is of standard 110 volts. If your drill’s motor, say 7 amps, then the maximum power output will be 770 watts (Watts =Volts x amps). Watts is not the best unit to consider when comparing the power of different drills.
Speed and torque will determine how powerful the drill is. Speed measured in rpm is simply how fast the drill spins and torque is measured in inches per pound, which is how much rotational force is behind the spin.
You’d find some impressive torque and speed in today’s top-quality corded power drill in the market. An 18 or 20 Volt will provide you with all the power you could ever need in your work around the house.
A larger power supply from the main outlet, coupled with a higher speed and torque, will make a corded power drill a favourite drill among serious DIY enthusiasts.
Mobility And Convenience
Besides having the convenience of mobility, a corded power drill does not have to be burdened with bulky and heavy batteries. That’s why you will find that the corded power drill is much smaller and leaner. When you get into a tight spot, a corded drill will help you to sneak in, where their bulky and heavier companion can’t fit.
No doubt, there’s nothing more convenient than popping in a battery and you are set to go. However, how long the charges can last will depend on the type of drilling you worked on. The power will expend fast if you are drilling on hard materials, draining the batteries. Constantly charging the batteries is a bit of a hassle but fortunately, most cordless power drills come with 2 sets of batteries.
You can make use of one battery while charging the other spare battery so that you’ll never be running out of power supply. With frequent use and charging, most batteries can not last long enough and need to be replaced when they cannot charge any more.
Drill Into Masonry
Your normal 4 Volt or 12 Volt cannot drill into masonry, it requires a drill with hammer action. Even though impact drivers also have a hammer that strikes both sideways and downwards on the bit but the force is only limited by its small voltage. Remember, a hammer drill is powered by a household current of 110 Volt.
Select a corded power drill with a low-speed gear if you drilling large-diameter holes in masonry. Choose to buy a hammer drill with multiple-speed features if working on other materials like plastic, metal or wood. BLACK+DECKER Hammer Drill, 1/2-Inch, 6.0-Amp (DR670) Shop at Walmart
Included Components: 1/2 ” Hammer Drill, Side Handle, Depth Rod Powerful and compact to handle tough tasks
Drill That Has Screwdriver Function
If you want a drill that can drive a screw and also remove screws, you need a drill that has variable speed and torque control and is also reversible.
If you’re looking for a drill that can change bits quickly and easily, without the need for additional tools choose a keyless chuck. The keyless chuck is found at the front nose of the drill where it can hold the drill or screw bit.
A Buying Guide For The Most Suitable Power Drill
There are multiple brands to remember and choosing one requires one to know what are their features and benefits, speed and torque ratings, cordless or corded that may be suitable for the kind of work you are embarking on now or in the near future.
Besides that, you would also factor in the type of power tool that is needed. Do you need to drill into concrete or just wood or both?
Do you have to drive small screws into softwood or big screws into hardwood? What is the type of drill that will solve your problems?

How To Maintain Your Power Tools
You have spent your hard-earned money to acquire those power tools, and of course, you’ll want to protect your investment. You want to make those tools last and the least you could do is practice some maintenance habits that can be applied on a daily basis.
Cool Down Motor and Tools
Working on your power drill continuously for a long period of time without stopping can put great stress on the motor and can cause it to overheat. This happens when working on difficult materials like drilling through masonry and very hard wood. Next time, if your tool is getting too hot, give it a break until it cools down. This saves your power drill from wearing out or your parts will wear out.
Power Tools Should Be Cleaned
Your power tools should be cleaned after every use before they are stored away. Cleaning the power tool with compressed air is the best option to clean the particles from its tool’s vent. It is not advisable to clean it with a brush as it would push the dirt farther into the tool which will inadvertently cause a more damaging problem later.
Lubricate The Tool’s Part
To ensure your power tools can last a long time, all the moving parts need to be lubricated. Your drill’s manufacturer’s manual will show you how to correctly lubricate and which lubrication to use on your particular tool’s make and model. A well-lubricated drill would prevent heating, chafing and corrodings.
Not To Use Worn Out Drill Bits And Saw Blades
Using worn-out drill bits or saw blades put more stress on your drill’s motor because the dull bits make it work even harder than before. It will cause overheating in the motor. It is important not to use old and damaged bits or parts in your power tool. Using the correct type of bit suitable for the job and compatible with the drill’s make is of utmost importance.
Calibrate Your Tools
Just like any precision instruments, your power tools which use lots of moving parts need to remain in alignment. Your User’s Manual will tell you when your tool is required to be celebrated, usually after a specified amount of use hours.
How To Store Your Tool When Not In Use
Your power drill should be cleaned and kept in a dry, clean place when not in use. Make sure it is not stored in a moist environment for it can be caused by corrosion and problems with the electrical components. It is best kept in the power case that comes with your purchase of the drill. The case will protect your grill from dust and particles from getting into the tool’s vents when kept inside.
Worn Parts To Be Replaced
Old and used parts will eventually need to be replaced to ensure your power drill can continue to function properly. The most common replacement is the tool’s carbon brushes, which are responsible for conducting electricity through the motor.
Do not overheat your power drill’s battery. Allowing it to overheat will fry it beyond repair. How to manage heat is key in managing your power drill’s life. Avoid leaving in an enclosed area at the back of a truck where temperatures spike. It’s good practice to recharge the battery before it is completely run down before recharging.
