DeWalt 18V XR Lithium-Ion Impact Driver Review
The Dewalt DCF885N impact driver is an extremely well-built piece of kit with high-quality components including an all-metal gearbox and an aluminium front housing that allows heat to disperse more efficiently and extend the working life of the tool.
LED lights help to illuminate the work area. The powerful motor can deliver 155 Nm of torque that translates into 3,200 impacts per minute and 2,800 rpm, ample performance for most day to day tasks.
The DeWalt impact driver has a compact profile and feels comfortable to hold with its well-moulded rubberised grip and weighs just 1.6 kg (without battery). If you are looking for one of the best 18 Volt impact drivers, then this comfortable, lightweight yet powerful model could be the ticket!
The Dewalt XR Lithium-Ion batteries used with this impact driver (typically 18 Volt and 4.0 Ah) are lightweight yet store significantly more charge with run times way longer than standard 18 Volt batteries.
Makita DTD153Z Brushless Impact Driver Review
The Makita DTD153Z Brushless Impact Driver is an impressive piece of kit. It’s not only cordless but brushless. Brushless motors use modified components that eliminate friction and reduce heat, so not only do they last longer but they work more efficiently delivering more power and make your jobs run smoother and quieter.
This impact driver also has a soft start and electric brake. This means that the initial power surge the tool experiences when starting up is controlled and makes the starting process more comfortable. The electric brake kicks in as soon you release the trigger and stops the chuck turning in around 2 seconds rather than waiting for the revs to decrease naturally.
The impact driver itself is compact and weighs just 1.3 kg (without the battery) yet can deliver great torque (170 Nm) and 3,600 impacts per minute, more than any of its competitors. This makes it a great choice for automotive use.
The build quality of the Makita impact driver is enhanced by Makita’s “Extreme Protection Technology” (XPT) that offers extra protection against dust and water.
It’s powered by Makita’s LXT battery system that uses Lithium-Ion batteries that can recharge in under 25 minutes. The impact driver comes “bare”, meaning you do have to purchase at least one extra battery and a charger, but that is the case with most impact drivers, and you can swap out the battery and use it with other Makita products.
Ryobi One+ Impact Driver Review
The Ryobi 1801M cordless impact driver is one of the most powerful impact drivers we recommend, generating a massive 220 Nm of torque.
This impact driver can deliver up to 3,400 beats per minute and 3,200 rpm. It’s therefore perfect for driving into dense material and breaking through pretty much any corroded nut or bolt! And yet it weighs just 1.63 kg and that includes the battery!
It has a strong protective cast gear housing, a standard keyless ¼” hex drive, variable speed control and an electric brake to almost instantly slow the chuck’s rotation when you release the trigger. It also has LED lights to illuminate your work area.
The Ryobi 1801M impact driver belongs to Ryobi’s One+ range of cordless power tools, meaning that although the tool comes “bare” (without battery or charger) once you do purchase the Lithium-Ion battery it can be swapped between more than 70 other Ryobi products.
BLACK+DECKER Lithium-Ion Impact Driver Review
The Black+Decker BDCIM18N is a great budget impact driver and also one of the most powerful. Its motor can generate 210 Nm of torque and variable speeds of up to 3,000 RPM, allowing it to drive most large screws and fasteners into masonry and concrete and loosen most rusted screws and bolts.
For increased durability, a metal casing encloses the gears, and the ¼” keyless chuck makes changing the bit effortless. The driver is lightweight (1.63 kg with battery) and easy to handle and operate with its anti-slip grip.
You do have to purchase a separate battery (a 3.0-4.0 Ah 18 Volt Lithium-Ion one is recommended) and charger but these can be used to run other Black+Decker 18 Volt power tools. Conversely, if you already have another Black+Decker 18 Volt cordless power tool then you don’t have to make any extra purchases!
VonHaus Cordless Impact Driver Review
The VonHaus cordless impact driver comes complete with battery (20 Volt Max, 3.0 Ah), charger and kit bag, and at a highly affordable price. The battery can also be used with other VonHaus Lithium-Ion “D-Series” power tools.
This is a robust impact driver with a cast aluminium gear head and motor that can generate 3,000 impacts per minute and with its variable speed control, up to 3,000 rpm. It also comes with LED worklights.
For an impact driver starter kit that ticks all the boxes, this represents great value for money.
Impact Driver FAQs
The impact driver is a very popular and versatile tool, not dissimilar to the general purpose drill driver. However, the impact driver can generate nearly 3 times as much torque!
Impact drivers are specifically designed to automatically overcome resistance encountered when driving. The user no longer has to apply extra force, as when using regular drills.
An impact driver is used where power is more important than precision. It is great for driving larger screws and fasteners into harder wood, masonry and even sheet rock, and some of the best impact drivers are used for automotive repair work. It is also perfect for tightening or loosening rusted bolts.
What Is An Impact Driver?
Most impact drivers are cordless, but there are corded and pneumatic versions too. They look like drill drivers but they’re smaller and have a more compact profile.
Their main feature is a shorter nose – this is due to the fact they don’t have a standard keyed or keyless chuck.
Instead they have a ¼” quick release locking collet into which you simply slot a hexagonal shank bit after pushing down on the collet ring.
They also have no torque control ring (this will be explained later on).
Also their motors are smaller than regular power drill motors because more power is generated by the impact motion itself.
Therefore smaller batteries can be used to power those smaller motors.
The compact profile, stubby nose, and lack of torque control ring on the impact driver make it quite distinct from a drill driver.
What Is An Impact Driver Used For?
Impact drivers are not only smaller and lighter than drill drivers but they are also much more powerful. So where would you use one?
Well if you are considering any sort of construction, home improvement project or automotive use read on!
They are great for driving larger screws, fasteners, and bolts into less forgiving materials like harder wood, masonry and stone.
These tasks would flatten your battery in minutes if you were using a drill driver!
So if you are building a deck or doing studwork, securing a timber frame, screwing down plywood or floorboard, hanging cabinets, driving into masonry or performing automotive work, then an impact driver is the tool of choice.
It is also great for tightening or loosening rusted bolts, lug nuts or screws in wood or metal.
But make sure you use specialist impact driver bits for these tasks since standard bits will quickly fail with the increased levels of impact applied.
Although not specifically designed for drilling holes, you can increase the impact driver’s versatility by adding a drill chuck adaptor.
This is a separate chuck with a spindle converted into a hexagonal shank that slots into the impact driver collet. It allows the impact driver to use standard bits and any other accessory with a round shank. A good example is using a spade bit for drilling large holes in lumber.
How Does An Impact Driver Work?
The key feature of an impact driver is its ability when driving to detect resistance and automatically apply an extra proportional level of impact (hence its name) or torque to overcome it.
The user has no control over when this extra force is applied, and therefore there are no torque settings.
When resistance is detected the motor engages a hammer which in turn strikes an anvil in the same direction the motor is turning.
These hammer blows or impulses are delivered at lightning speed, up to 3,000 beats per minute, in order to apply the extra rotational force or torque required to overcome the resistance.
When there is no more resistance the hammer anvil action stops, but the cycle will restart if further resistance is encountered.
The other great feature of this mechanism is that you don’t get kickback. When regular drills encounter resistance the drill bit can sometimes get stuck. When this happens the rotational force can be transferred from the drill bit back to the drill itself. If the drill bit is still tight in the chuck, the unwanted force can trigger back to the user, causing the whole drill to spin and possible injury to wrists and hands.
What Impact Driver Main Features And Specifications Should I Be Looking For?
The best impact drivers are all relatively lightweight, have a ¼” collet, and can deliver around 3,000 bpm (beats /impacts per minute).
No-load speed is around 3,000 rpm and max torque ratings over 200Nm, around 3 times that of a drill driver.
More expensive models may have more than one gear. The best impact drivers are brushless, but having a brushless motor is in no way essential.
Although there is no torque ring, some do come with an integrated clutch. This is useful because it can be engaged if you think you are going to over-tighten a screw on account of the higher torque being delivered.
This is quite a noisy tool!
Impact Driver Variations
Impact wrenches are similar to impact drivers. They too are designed to overcome resistance but they are designed to work in a twisting or horizontal mode, as opposed to impact drivers that apply force vertically. Therefore impact wrenches are ideal for tightening and loosening bolts.
Impact drivers come with a ¼” female hexagonal drive, but impact wrenches come with a ⅜” or ½” square drive.
What Shouldn’t An Impact Driver Be Used For?
The Impact driver is a powerful tool and should not be used for delicate tasks, primarily because you cannot control exactly when the torque surges kick in.
So don’t use it for self-assembly furniture, tightening smaller screws into metal or anywhere you want to drill precise holes. You may not get the clean finish you desire, so use a drill driver instead!
Neither should an impact driver be used as a hammer drill. The percussion action on a hammer drill is applied vertically and constantly with added force by the user, whilst impact driver action is applied sideways, irregularly (when extra resistance is met) and automatically.
