What is ‘No Load Speed’?
The maximum speed a cordless drill driver can reach without a load (when it’s not driving screws or drilling holes).
Manufacturers give the tool’s speed at no-load because once the drill driver begins driving screws or drilling, its maximum speed will vary depending on how demanding the task is.
A cordless drill driver’s speed will be presented as a number followed by ‘RPM’. The higher the number, the higher the tool’s maximum no-load speed.
