Choosing the right speed

Shop for Cordless Screwdrivers

Lower speeds are better for…

Driving larger screws

Larger screws require more torque and so they should be driven at slower speeds.

Drilling or driving into tough materials

Drilling or driving into tough materials (e.g. ceramic or hardwood) requires more torque, and should be done at slower speeds.

Please note:

When continuously drilling or driving at lower speeds, the motor can become very hot.

To ensure the motor does not overheat, WONKEE DONKEE advises that you occasionally remove the cordless screwdriver from the work surface and run it at a high speed for a few seconds.

This will allow the motor to cool itself down.

Higher speeds are better for…

Driving screws or drilling into soft materials

Driving screws or drilling into soft materials (e.g. softwood) requires less torque so it can be done at higher speeds.

Please note:

Drilling and screw-driving at high speeds can cause the metal bit and screw to heat up.

If you are working with plastic at high speed, the screwdriver or drill bit can overheat and melt the plastic.

To prevent this, work at a slower speed and check the material frequently.
