DeWalt launched a new 20 Volt MAX 1/4-inch Impact Driver that will use a brushless motor. The DCF895 will be available in three different configurations and users will find that the new technology brings longer run time in a more compact platform. Brushless motors work more efficiently when compared to brushed motors. In fact when DeWalt compared it to their current 20V MAX impact driver, it has 57% longer run time.
To transfer energy from the battery to the motor in a brushed motor, they rely on contact between carbon brushes and a rotating armature. The brushes generates heat, wastes energy and causes friction because they are under constant pressure since they are spring-loaded. The new DeWalt brushless motor uses electronics and software designed to run the motor at its highest efficiency and performance. As a result, the new brushless motor system consumes less energy when compared to the brushed motors. These improvements in technology allow the tool to run longer between charges and stay cooler.
“I spend a great amount of my time on job sites talking to end users about their demands in a tool, so I can attest that longer run time is the primary concern among many professional contractors, DEWALT power tool users will find that our new BL has an extended run time, and therefore lasts longer between charges. This leads to greater productivity on the job site and less downtime.”

We have been accustomed to cordless drill/drivers with multi speed transmissions, so why shouldn’t we expect it in impact drivers too? The DeWalt DCF895 20 Volt MAX Brushless Impact Driver comes with a electro-mechanical switch that allows the user to choose between three speeds. Woodworkers and electricians can use the first setting (0-950 RPM; 500 inch/pounds Max Torque) for finish work and using easily damaged fasteners. For many contractors the middle setting (0-1,900 RPM; 900 inch/pounds Max Torque) will be a favorite since it can give extra control for many fastening applications such as door hinge installation. The last setting (0-2850 RPM; 1,500 inch/pounds Max Torque) is best suited for high torque and high speed applications like driving self-tapping screws into metal.
In addition to the brushless motors, the new impact drivers include other innovative features as well. The first that many users will notice is the push button, 1/4-inch chuck. This chuck accepts 1-inch bit tips and allows users to accomplish one-handed bit changes with the push of a button. For better visibility, these impact drivers have three LED lights surrounding the chuck with a 20-second delay after trigger release to provide light without shadows. Last but not least, the battery packs will come with a built in fuel gauge that indicates the state of charge of the battery.
Weighing in at only 3.0 pounds (DCF895C2) and 3.6 pounds (DCF895L2) and at just 5 1/4 inches in length, these are the shortest impact drivers that DeWalt offers. The premium model DCF895L2 comes with two 3.0 Ah batteries and will retail for around $349. The compact DCF895C2 comes with two 1.5AH batteries and will sell for about $279. For those that already have other 20V MAX tools and don’t need more batteries and a charger, then a bare tool model DCF895B will be sold for roughly $169.
