Best Impact Drivers - Top Picks, Reviews & Complete Buying Guide
by Scott Miller Updated on
When you are interested in having some tools at your house just in case you need them, a drill is probably the first one that you would buy.
However, the more you get involved in this field, you find out that there are situations where the drill cannot handle the job, due to the fact that it does not have the torque of the capacity that an impact driver has.
Still, you should know that the impact driver is not a replacement for a drill and it should just be the additional tool in your tool kit.
Now, being that you are reading this, you are in search of an impact driver, but you probably do not know where to begin and what to look for.
In order to help you, we have collected all the necessary information related to impact driver and created this article which includes a detailed buying guide.
By the end of this page, you will know what the best impact driver is for you.
On a list of the best impact drivers available on the market, five of them found their places.
The list is made according to the specifications of products and customers‘reviews.
Being in the first place, the most worthy impact driver is due to its durability and performance is the DEWALT DC825B model.
Again, DeWalt could not but produce the top quality tool that leaves all the other models behind.
One of many reasons why this is the best 18-Volt impact driver on the market is the fact that the machine delivers 1330 in/lb of torque at 2400 rpm and 2700 rpm.
This proves the fact that this tool is ideal for heavy-duty tasks and it can drive fasteners into wood, metal, or concrete.
Additional outstanding feature is a variable speed trigger which enables you to increase the speed, number of impacts, and torque and that is regulated by the pressure on the trigger.
The quality of DeWalt’s trigger’s responsiveness and control is not in question.
What makes it even better is that the tool is lightweight and compact and the way of changing the accessory is quick and easy.
The body of the device has an anti-slip ergonomic grip, the gear case is made of magnesium and the transmission is all metal, so the combination of these materials makes the tool both comfortable and durable.
Still, each device has its drawback, and DEWALT DC825B model was not an exception.
The tool is powered by a NiCad battery and not Li-ion.
When the power is in question, both NiCad and Li-ion batteries deliver the same amount of power, but NiCad batteries are prone to memory effect and self-discharge.
Another disadvantage of this model is the cost.
The tool itself costs about $100 but you will need a 2 Ah battery and its charger which will cost you around $150 to $175.
Nevertheless, the tool comes with a 3-year limited warranty which proves the faith of its producers in this model.
The price is high, but you should know that what you get is the tool with amazing performance, long life, and excellent purchase protection.
The models mentioned above are all high-powered 18 and 20-Volt impact drivers.
However, the powerful impact drivers are more suitable for heavy-duty tasks and longer working periods.
For occasional usage, we do not need such powerful devices and the 12-Volt class of impact drivers is quite satisfactory.
The lack of power is complemented by great portability characteristics.
Moreover, it is an economical device.
The M12 Impact Driver Kit includes the M12 impact driver, a 12-Volt Li-ion battery, a charger and a carry case.
If you take a look at the price of this device, you would think that as it is a low-cost machine, the warranty period would be short, but that is not the case with the M12 which comes with a 5-year warranty.
The maximum no-load speed of the M12 is 2500 rpm and it is able to produce 3300 impacts per minute at 1000 in/lb of torque.
The lack of torque is replaced by the increasing number of impacts per minute.
This makes the M12 performance the best in this class.
The machine is powered by the REDLITHIUM™ which delivers 80 percent more runtime than other batteries.
It has a fuel gauge on board showing you the remaining runtime.
Additional features entail one-hand accessory change, ergonomic grip, and a tool belt.
All in all, the M12 is light, cost-effective, compact, and powerful, which means that it is a great value for money.
On the last place on our list is the Porter Cable model of an impact driver.
This producer has offered a powerful and budget-friendly impact driver.
The PCCK640LB kit includes a 20-Volt impact driver, two 1.5 Ah battery packs, and a charger.
When we think about the device itself, we can say that the PCC640 impact driver runs at a maximum speed of 2900 rpm and produces a torque of 1495 in/lb at 3100 impacts per minute.
If you take into consideration the price, this is definitely worth buying.
There are no critical features missing, in fact there are additional ones such as an easy-load chuck, an LED illumination light, a variable speed trigger, and a battery charge indicator.
All impact drivers have these features, this is not an advantage and if this one would not have them that would be a big drawback.
The disadvantage is that the PCC640’s motor is rather large and weighty so the whole machine is heavier.
The durability is lower than with other models, due to the fact that the internal mechanism has a lot of moving parts.
The last weakness of this model is the fact that Porter Cable offers only a 1-year limited warranty.
This is the good choice only if you are on the budget.
As you are ready to choose the ideal impact driver for your needs, you will have to think about spending quite a bit of money on it if you really want a quality model.
If you cannot afford those expensive ones or you do not need such an advanced tool, we give you some hints how to choose the one you need.
I have a drill. Do I need an impact driver?
The very frequently asked question is whether to buy an impact driver if I already have a drill.
The answer to this question is definitely – Yes, you should get it.
The best way of explaining why a drill cannot replace an impact driver and vice versa is via an example.
The kitchen of a person who cooks daily and takes this job very seriously is full of sets of knives, not just one knife.
One knife that cuts well is enough for an amateur, but not for a chef.
The same is with drills and impact drivers.
Your home tools, if you take this job seriously, should include a drill and an impact driver, even though they both serve the same purpose.
The advantage of an impact driver is that it delivers more torque than a drill does, meaning that you can do so many things with it that you would not be able to do with a drill.
If we compare the DEWALT DC825B impact driver with the DEWALT DC759KA, a heavy-duty cordless drill we can see that some of their characteristics are equal, but some are not.
The similarity is that both machines run on an 18 V system.
However, the torque that the impact driver would produce is 3.5 times higher than the drill.
So, small fasteners can be done with a drill, but the impact driver is perfect for larger fasteners.
How is it possible that an impact driver can produce so much torque?
As you are wondering how it is possible that an impact driver can produce so much torque, we will explain it to you.
The principle on which the impact driver works is the following.
When the impact driver encounters struggle, there are a lot of tiny hammers inside the device which will strike the anvil and give it extra rotational force.
Or, you can say – extra torque.
So, this principle is the secret weapon that is behind the impact drivers’ incredible power.
What parameters should I have in mind prior to purchasing an impact driver?
The performance parameters, as well as the characteristics related to batteries, are something that you should pay attention to prior to purchasing an impact driver.
Drive Size – This determines the type of accessories compatible with the driver and the most common is the 1/4-inch hex type. Accessories with a hexagonal shank of 1/4-inch size would be applicable to the device. Also, it is important to note that when you buy accessories for your impact driver, they have to be designed for “impact”.
Impacts Per Minute – This is the number of times the hammer strikes the drive per minute. If we take the DEWALT DC825B model as an example, we can say that this machine delivers 1330 impacts per minute when the shank rotates at 2400 rpm. So, the conclusion is, the higher the number, the better the performance of the device.
No-Load Speed – The speed at which the drive rotates at no load or the speed at which you can drive the fastener.
Torque – the most vital characteristic of every impact driver. The torque is a measure of the rotational force. The good impact driver should have a higher number of blows per rpm, but those blows should be powerful. So, the better performance can be expected from a model that delivers fewer blows per minute but has greater torque.
Battery Capacity – this is measured in Ah, and as in the majority of cases, the higher the number, the greater the battery’s capacity would be. However, the higher capacity of the battery is followed by the higher prices, weight, size, and charging time.
Charging Time – This is the time necessary for a battery to fully charge. The 2 Ah battery takes from 30 minutes to 60 minutes to charge.
And one more tip in the end.
Impact drivers come without a battery or a charger, so the solution is to look for combo packs as that would be much cheaper than buying a tool, a battery and a charger individually.
What are the most important features?
The impact driver does not have so many features to look for as it is not too complex tool.
What you can have in mind that an impact driver should have tool-less accessory change which will make your work easier and more efficient.
Additionally, if you need a more advanced one, you can think about having a brushless motor, ergonomic grip, variable speed setting, the longer warranty period and an illumination light.
I think I got it, what are my options?
If you have checked our list of the best impact drivers and you still have not found a suitable product for you, maybe you can go through the official websites of impact driver producers and check what the specifications are for some other models not mentioned on our list.
But, have in mind that we made a list which is designed to match a wide array of customer profiles and we are sure that if you pick one of the above mentioned models, you would not regret it.
The brands that you should explore are Bosch, Makita, Milwaukee, and DEWALT.
Conclusion
As we come to an end of this article, we want to make a short summery of all the things we spoke about so far.
If a budget is not an issue, the best impact driver for you is definitely the DEWALT DC825B – the best performing and durable impact driver which is on the top of our list.
If you cannot afford this the most expensive model, you can go for the Ryobi ONE+.
It is the most affordable and powerful, but not as durable as the DC825B.
The second DEWALT model is the DCF887B, with a 3-speed setting and it is a great replacement for a drill.
However, if you already possess a drill, then this device is not worth that money.
The Milwaukee M12 is proud of its portability and the longest warranty, but it cannot boasts with a battery and charger.
The last one on our list is the Porter Cable Impact Driver Kit, a budget-friendly one but not as reliable impact driver as all the others mentioned before it.
In conclusion, there are a lot of impact drivers on the market and depending on your needs, budget and expectations you are the only one that can make the right decision.
