Buying Guide
Choosing the Right Portable Angle Grinder

Power and Voltage
Consider the power source and the jobs demands. Corded grinders offer consistent power, typically 6-15 amps. Battery-powered grinders offer portability; common voltages are 18V or 20V. Higher voltage usually indicates more power, suitable for tougher tasks like removing rust from steel.
Disc Size
The disc size affects cutting depth and the area covered. Common sizes are 4.5-inch, 5-inch, and 6-inch. Smaller discs are ideal for detail work, while larger discs are best for broader surfaces and thicker materials.

Prioritize safety. Look for features like a guard to protect from sparks and debris, a two-stage trigger to prevent accidental starts, and a vibration-dampening system for comfortable use. A side handle improves control, which enhances safety.
