Drill Drivers vs Hammer Drills Compared to Impact Drivers

I felt it would be really helpful if I talk about the variations between impact drivers, regular drills, and hammer drills.

The differences weren’t quite clear to me so I chose to take a step back and rethink and review what the similarities and differences were. The slight dissimilarities can be clarified with a couple basic analogies however I’m certain a few individuals may find fault with my clarifications. In any case, at last you’ll get to know what the different drills do and how they do it, so let’s take a look!


You know them, you adore them, and those who have been wood working for years, have probably owned at least a couple of these. Throughout the years they’ve shed a couple pounds, been stripped of their chords, and we’ve seen the inclusion of keyless features and on-board lights. Be that as it may, for every one of the new common luxuries, these drills all work in practically identical ways.

They are moderately priced, reliable, adaptable, and they are ideal for both driving screws and drilling holes. In any case, for some unique assignments, there are unquestionably more suitable choices available, and you’ll learn about them later. These drills are available in all sizes and shapes and voltages including 20 volt batteries.

Be that as it may, don’t forget, in case you’re a shop carpenter, bigger is not generally better. A large, capable drill/driver may be helpful at work sites where you can utilize the drill for a considerable length of time without an ideal spot to charge.

In a little shop, you generally have the alternative to charge it and you seldom utilize the instrument for a considerable length of time. So consider working with a smaller drill as it is light to bear and fits into smaller spaces.

A hammer drill essentially resembles the regular drill, which sometimes confuses individuals. Actually, you can discover various models out there that feature both a hammer and regular setting.

So what is the function of the hammer setting?

Envision you’re drilling with the drill and somebody is using a hammer to hit the back of the drill to push it further into the work. This is essentially the workings when a hammer drill is used, just that the hammer hits are quick and angry.

This sort of drill is boisterous and has the feel of a small jackhammer in your grasp. The first time I turned on the drill, I thought it was broken! These drills exceed expectations at pushing through concrete and other granite surfaces. So on the off chance that you do a great deal of stonework, this is unquestionably a drill that you need to own.

From the perspective of a shop carpenter, you won’t generally need a hammer drill for much aside from the infrequent DIY task.


Featured: The Makita Impact Driver – No. 1 Seller on Amazon.com

The impact driver is THE woodworking tool of choice. It’s neither a hammer drill nor a regular drill/driver. Its appearance is distinctive with a little squat profile and a hex attachment instead of a chuck.

So how does an impact driver work?

We should consider another similarity. Envision you own a couple of vise grips joined to the shank of your bore. Then rather than somebody simply hitting the drill’s back, they are likewise hitting the vise grips to turn the bit. This leads to a noticeable increment in torque and superior control. It additionally implies that you are substantially less prone to strip screw heads and can also drive long screws with little exertion and insignificant wrist movement.

The device really is responsible for the work and the impact action switches on naturally when it’s required. The disadvantage is that you aren’t generally aware of when it will kick in. As such, it may be hazardous to utilize this drill on your expensive metal equipment or on delicate operations where the depth of the screw is important. However, in the event that you are driving screws for general project assembly, cabinet installations, or DIY ventures, this drill is definitely astounding.

So we should talk about the impact driver somewhat more and run over my encounters using the DeWalt combo unit. As a shop-based carpenter, my drilling works are truly basic. So the vast majority of my drills are achieved using a basic drill/driver. In any case, at whatever time I have to drive a screw, I use the impact driver. In the event that I were installing a great deal of on-site works, the impact driver is definitely useful.

Also, as a landlord and DIY’er, an impact driver truly makes life less demanding. I’ve been upgrading a great deal of shop features recently, as well as installing new florescent lights and mounting up my ClearVue cyclone dust collector, and the impact driver has been extremely valuable.

I achieved this with just one hand, standing on a ladder, and using my other hand to film the procedure so I apologize for the bad quality. Yet, as should be obvious, it required almost no push to drive in the screw. So one final thing you ought to be aware of regarding impact drivers is the fact that they function solely with hex shaft bits. The vast majority of my bits do, and as such it wasn’t hard for me.


Clearly, I can’t cover all conceivable working scenarios so I’ll give a general suggestion for individuals who work like me: producers, DIY’ers, and shop carpenters. Purchase the Combo Kit!

Essentially every drill maker has a combo unit boasting both an impact driver and a regular drill. This is really the best choice, offering you a general drill for making holes that can take pretty much any piece and an impact driver for driving screws with hex bits. I believe the three combo units listed below are worth looking into:

• Bosch 18v Combo
• Milwaukee 18v Combo (click to read review)
• DeWalt 18V Combo

Cordless handheld drills have a power range of 2.4-36 volts. The power of a handheld drill determines what the drill can do. A hammer drill is the most powerful kind of handheld drill.


The most powerful cordless drill is a cordless hammer drill. It runs at 18-36 volts.

Cordless hammer drills are heavier than the other kinds of cordless drills. A hammer drill automatically increases the torque when it senses increased resistance, so it normally does not need pilot holes. It can also punch through brick and concrete.

Most cordless hammer drills have an adjustable clutch with a special hammer setting where the drill bit punches in and out as it spins. Special drill bits are usually needed for the hammer setting. You should also use hearing protection.


A standard hammer drill can drill into wood, drywall, light metal, and any other surface up to brick and concrete. It can drive and remove standard and long screws without pilot holes. It can use larger drill bits to drill larger holes. It is easy to handle, but most hammer drills are heavier than other types of cordless drills.

The adjustable clutch automatically increases the torque when it senses increased resistance. You do not have to put as much pressure behind the drill as you do with a standard cordless drill. You will need to apply more pressure to hammer drills with lower voltage.

In the hammer setting, the drill bit punches in and out as it spins. Special drill bits are needed for the hammer setting.

A good hammer drill has two gears. Low gear is used to drive screws. High gear is used for rotary drilling.


The other kinds of cordless drills are the basic cordless drill, the cordless screwdriver, and the cordless impact driver.

The most common DIY cordless drill is the basic cordless drill. It usually runs at 9.6-18 volts. It can drill into wood, drywall, or light metal. It can also drive and remove screws. It often uses an adjustable clutch to switch from drill bits to screwdriver bits.

A cordless impact driver is like a basic cordless drill with a torque upgrade. It normally runs at 14.4-20 volts. This drill will usually automatically increase the torque when it senses increased resistance. This keeps the bit from slipping out of the screw head and stripping the screw. It does not normally need pilot holes.

A cordless screwdriver generally runs at 2.4-10.8 volts. It should not be used for anything except driving screws into basic materials. Avoid very low voltage cordless screwdrivers.


Avoid buying a cordless drill based on power alone. Make sure the drill has what you need and does not have too many things that you will never need. You should plan for the future, but you should not buy more drill than you will ever need.

Do not buy a cordless screwdriver unless you will never use a cordless drill for anything except hanging pictures. Do not buy a hammer drill unless you know for sure that you will need to drill into concrete. Do not buy extra gadgets that you will probably never use.

The most powerful cordless drill is a cordless hammer drill. It runs at 18-36 volts. Higher voltages have much more torque. If you are buying a cordless hammer drill, it is better to pay a little more to buy a hammer drill with higher voltage.


The basic battery is the nickel-cadmium (NiCd) battery. It is also the cheapest battery. It has a short life and it takes hours to recharge. Avoid NiCd batteries for cordless hammer drills.

Lithium (Li-ion) or nickel-metal-hydride (NiMH) batteries have higher power and longer run time than NiCd batteries. You should get lithium batteries if you do frequent DIY work with a cordless hammer drill. They charge in 30 minutes or less. They also weigh less than NiCd batteris.

Lithium batteries come in slim and fat sizes. The fat batteries cost more and last longer between charges.

You should never run a lithium battery down completely. You will not be able to recharge it. Some cordless hammer drills come with a battery charge monitor that tells you how much charge is left.


Cordless hammer drills come with many different accessories and options. The most useful accessories are a tool belt hook and a bright work light. You should also get a hex drill bit set.


If you do not already have protective eyewear, buy it at the same time as you are buying your cordless drill. Always wear protective eyewear when using a cordless drill.

A hammer drill can make many of your home repair and renovation projects easier. This style of drill combines a rotating drill bit with jackhammer operation. Hammer drills cut cleanly through hard surfaces like brick and concrete when you need to anchor items. Once you learn how to use a hammer drill the right way, you can find many reasons for owning one.


Learning how to use a hammer drill safely is very important. This is a powerful tool and capable of causing injury and damage. Always wear safety glasses, as brick and concrete chips can easily fly into your face. For indoor work, a dust mask is desirable. Construction grade drills can be very heavy. If you are working on a ladder, make sure that you can support the drill without falling off. This same rule applies if you are using an extremely long drill bit.

All power tools should be given a quick safety inspection before use. Your owners manual should provide a list of key points to inspect. Many hammer drills have a safety release that is designed to stop the rotating action if the bit becomes jammed. This is actually a critical feature if you are working with a powerful drill. The torque of the drill can cause the body to spin if the safety release malfunctions. If your drill is equipped with this release, make sure it is operational.


Hammer drills are not meant to be used on softer surfaces like wood or drywall. They will rip right through these materials. If you need to drill a large hole for anchoring heavy lugs, start with a smaller bit to create a pilot hole. Line the drill up so it is level to your mark, either vertically or horizontally. You need to apply even pressure and keep the entire drill straight and level while you are working.

If you need to chip out brick or concrete for a larger installation, mark the corners or diameter area first. Start with small pilot holes just inside the marks you made. Once you have outlined the area to the appropriate depth you can begin to work with a larger bit for material removal.


No matter what type of drill you are using, always know what you are drilling into. A hammer drill can cut through material quickly, if you are unsure of your drilling depth use the shortest bit possible. It can be very easy to drill completely through the exterior of your home and into the living area if you are not careful.

Make sure that your drill bits are always sharp and installed in the drill correctly. Loose or wobbly bits will not cut properly and may cause surface damage. Dull bits create heat as they cut and make your job much more difficult. You can spray the surface of brick or concrete to minimize dust and heat build up.
