The building and construction industry involves a lot of drilling and driving or removal of small and large screws and bolts from soft and hard materials. Without the right tool, the work can really be unnecessarily time-consuming and difficult with average outcome. Thanks to the cordless impact driver that not only gives you freedom from hoses and power cords but also brings speed and professionalism into how you drill holes and install screws and bolt fasteners.
A cordless impact driver is a battery-powered tool that delivers a huge amount of torque to drill holes and drive screws and bolts into hard materials like heavy steel, hardwood, or pressure-treated lumber quickly and easily. Like the impact wrench, the driver uses lateral impact to twist screws and drill bits in or out of material. However, the impact driver does not deliver as much torque as an impact wrench and therefore cannot be used to break lose large lug nuts and bolts. The tool works both as a drill and a driver. As a drill, the power tool uses hex shank drill bits rated specifically for an impact driver to make holes. It can also use spade bits to bore out large holes. When used to drive bolts and screws, the cordless impact driver utilizes impact sockets because the regular ones can shatter with impact.
Selecting the best cordless impact driver for your trade among competing alternatives is not simple. However, after thorough research and rigorous tests, this article presents the 5 best cordless impact driver tools for easy selection.

Operation Modes of the Milwaukee Cordless Impact Driver
Mode 1 delivers up to 200 inch-pounds at a maximum variable speed of 850 RPM. In this mode, the tool starts by driving the screws quite fast and slows down as the head approaches the surface upon which it begins to impact to ensure the screw head is flush without overtightening. This mode is ideal for tightening door hinge screws.
In Mode 2, the Milwaukee 18V impact driver delivers up to 700 inch-pounds and a maximum of 2100RPM that can be varied using the speed trigger. It is usually the preferred operation mode for mechanics to tighten automotive nuts.
Mode 3 delivers all the torque and the maximum possible RPM. It is the preferred mode of operation for driving screws through metal and works very well when doing steel stud framing. In other words, mode 3 is ideal for heavy duty applications.
Mode 4 (Self-tapping mode)
The fourth mode of operation is usually known as the Self-tapping mode. It is purposely meant to drive self-tapping screws because it provides custom speed and power needs. In this mode of operation, the driver starts at a controlled speed that ramps up gradually to 3000RPM. The controlled start prevents walking. The maximum speed, on the other hand, ensures that the self-tapping screw winds through its threads quickly. As the head approaches the surface, the speed slows automatically to about 750 RPM to prevent breaking or stripping out the screw. Additionally, the tool begins to impact slowly to ensure that the screw is flush without overdriving.
Milwaukee M18 Fuel Impact Driver is an incredible tool that combines power, efficiency, precision, and an amazing operator control to provide an unmatched working experience.

Factor to Consider When Selecting a Cordless Impact Driver Kit
The knowledge of how the best impact drivers compare is not all it takes to make the best and most informed selection. The following factors also need to be put into consideration before spending on an cordless impact driver.
The clutch is responsible for adjusting the amount of force exerted onto a screw. The best cordless impact driver is one whose clutch has the widest selection. Out of the five best impact drivers, Milwaukee M18 fuel impact driver and DeWalt impact driver have the 3 torque selections each. In addition, Milwaukee has a fourth selection that automatically adjusts the lateral force to drive self-tapping screws safely and efficiently without stripping or walking.
You can select the battery powered impact driver based on your needs. If you are a homeowner looking for a tool that will perform light tasks around the house, you can go for impact drivers that do not deliver a lot of torque. Alternatively, you can just consider other factors because any tool will either deliver as much torque as you need or will give you more control.
Batteries can be a huge saving when purchasing cordless tools. You do not need to buy extra batteries and charger if you already have other battery powered tools that use the same battery line up. For instance, if you have already invested in Milwaukee’s M18 battery lineup, it is economical and more reasonable to stick with Milwaukee fuel impact driver even if Dewalt seems best to you.
Ability to control the speed of the driver helps you protect screws from damage. For instance, high speed can strip screws or overdrive them into material. The best cordless impact are those that give an operator the control over speed either through a variable speed trigger or by having various speed settings. The Milwaukee 2753-22CT and Dewalt DCF887D2 impact drivers have a range of speed settings that an operator can select when driving different screws, bolts, and nuts.
There are two types of motors; brushed and brushless motor. Brushless motors are more efficient, do not spark, and do not require maintenance. Brushed motors, on the other hand, spark, are less efficient, overheat more under load but less expensive. Out of the five cordless impact drivers, Makita and Teccpo are brushed and the rest are brushless. Depending on the compromise you want to make between cost and efficiency, you can choose the tool that works for you.
Some lithium ion impact drivers cost a lot more than others. Some cost as low as below $100 while others cost close to $200. Hitachi and Teccpo are among the cheapest in the best cordless impact drivers class.
Tools are a huge investment and their insurance after purchase is very important. All the five impact drivers have warranty cover but the periods of cover varies significantly. Hitachi tops the list with an unmatched lifetime warranty cover on the tool while Dewalt only provides a year of cover. Milwaukee is second with 5 years cover followed by Makita which offers 3 years cover and Teccpo with 2 years of cover.
By taking all those factors into consideration, you can make a more informed decision before you place money on any tool.
