What is the speed of a cordless impact driver?
The speed of a cordless impact driver is measured in RPM (revolutions per minute) - one full turn of the chuck equals one turn. The maximum "no load" speed of the tool will be represented as a number followed by "RPM". The higher the number, the more revolutions the chuck can make in one minute and the faster it can turn a screwdriver bit or drill bit.
When choosing a cordless impact driver, you will find that manufacturers usually list the tool's maximum speed as "no load".This is the maximum speed at which the cartridge can rotate without load (when it is on and the trigger is fully pulled, but this is not driving screws or drilling holes).Manufacturers indicate the speed of the tool without load because once the impact tool starts to drive screws or drill, its maximum speed will vary depending on the load (screw size and type of material).When working with very large screws or tough materials, the cordless impact driver may slow down as it tries to overcome resistance. How much will depend on the specific task at hand.Most cordless impact wrenches have a maximum no-load speed of around 2,500 rpm. For comparison, an average cordless screwdriver can reach 200 rpm, and an average cordless screwdriver can reach 1000 rpm.Simply put, a wireless percussion instrument with a higher maximum speed will be able to complete the same task in less time than an instrument with a lower maximum speed. However, the higher the speed, the more expensive that particular model will be.

On the other hand, you can expect to get the job done quickly, so more RPMs will be a priority.
