What’s the difference between soft-start and variable-speed angle grinders?​

Soft-start is a startup feature: it makes the tool accelerate gradually, reducing sudden torque and electrical surges. It focuses on safer, smoother initiation, protecting both user and motor.​

Variable speed, however, lets you adjust the running speed during use. By tweaking RPM, it adapts to tasks—lower speeds for delicate work like polishing, higher for tough cuts. It enhances versatility, not just startup control.​

In short, soft-start eases the start; variable speed controls the entire operation. They serve different stages but both boost usability.
