20V

20V

A tool/machine with a higher voltage produces more power.
2.Has variable speed
DeWalt DCD771
DeWalt DCD985B
A drill with variable speed allows you to switch between low and high speeds, giving you the possibility to take on a wider range of tasks.
Higher speeds work better for drilling holes in certain types of material, such as steel, aluminium, concrete, etc. The drill speed is measured in rotations per minute (rpm) when the drill has no-load.
