Buying Guide
Brushless Angle Grinder Buying Guide
A brushless angle grinder is a powerful tool for grinding, cutting, and polishing. Choosing the right one depends on your needs. Heres what to consider:
Power & Voltage
Consider the voltage. 18V or 20V models are common for cordless grinders, offering good portability and power. For heavy-duty tasks, a corded grinder with a higher amperage (e.g., 6-8 amps) provides more consistent power.
Disc Size
Angle grinders typically use discs ranging from 4.5 inches to 9 inches in diameter. Smaller discs are suitable for detail work and lighter materials like metal sheets, while larger discs are best for thicker materials and faster material removal, like concrete.
Features
Look for features like a variable speed setting for controlling the grinding speed based on the material. Safety features like a lock-on switch, a guard, and an anti-vibration handle can improve user safety and comfort.
Brand Reputation and Build Quality
Opt for well-known brands like DeWalt, Makita, or Bosch, which are known for quality and provide excellent warranty and support. Examine the tools build quality for durability and long-term performance.
