Is a higher RPM always better for an electric screwdriver?

No. Higher RPM is not always better for an electric screwdriver. The right speed depends on the screw size, material, torque, and application.

Higher RPM is useful for:

Removing screws faster

Increasing efficiency during repetitive assembly

Working with longer screws before final tightening

Lower or moderate RPM is better for:

Small precision screws

Phones, laptops, cameras, and watches

Plastic threads and delicate housings

Final screw seating

Applications where screw damage must be minimized

Excessive RPM can increase:

Cam-out and bit slipping

Screw-head damage

Over-driving

Heat and wear

Difficulty stopping accurately when the screw reaches its final position

For precision repair, torque control, bit accuracy, and speed stability are usually more important than maximum RPM.

ToolQeen multi-stage precision electric screwdrivers typically use speed levels around 650, 800, 900, and 950 RPM, matched with adjustable torque levels for different repair applications.

For OEM projects, ToolQeen can adjust the RPM, torque settings, motor, gearbox, and PCB control according to the target screw size, material, and working application.
