What is no-load speed?
|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.
|This is 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.
|For example, if you’re driving in large screws or working with tough materials the drill driver is likely to encounter resistance, causing the speed to be reduced.
|Please note: A cordless drill driver with a high RPM can turn the chuck at a higher speed but it will not be able to complete tasks any quicker, unless it can also deliver the required torque.
If you want to complete tasks in less time, look for a model that can produce both high RPM and a high level of torque.
