A drill screwdriver is a hybrid device with which you can not only tighten fasteners, but also drill holes. We explain how such devices differ from most ordinary screwdrivers, and how to choose the model suitable for your tasks.
How is a drill different from a conventional screwdriver?
A conventional screwdriver is intended exclusively for screwing / unscrewing screws, self-tapping screws and other fasteners. We already wrote about the features of choosing cordless screwdrivers, so we will not repeat. We only note that such a power tool operates at low speed (although there are also high-speed models), but with high torque. Thanks to its high torque, even the most stubborn screws can be loosened. Normally, “shuriks” are equipped with ammo for a bat.
The drill driver has at least two speeds: one low for twisting, and the second high for drilling. If the device has several speeds, this does not mean that you have a drill / driver. Their main difference is the presence of a drilling mode. Screwdrivers are equipped with a chuck (quick-clamping or specialized), in which drills can be clamped. The characteristics also indicate the diameters of the holes that the device is capable of drilling in metal and wood.
