Buying Guide
Air Powered Angle Grinder Buying Guide
Choosing the right air-powered angle grinder depends on your specific needs. Heres a quick guide to help you:
Power & Air Consumption
Consider the tools horsepower (HP) and required cubic feet per minute (CFM). Higher HP delivers more cutting and grinding power, ideal for tough materials. Make sure your air compressor can supply the necessary CFM to the grinder to avoid loss of power. A grinder requiring 4 CFM will work better with a compressor that supplies at least 5 CFM at the same pressure.
Size & Disc Diameter
Angle grinders come in various sizes, with disc diameters typically ranging from 4 to 9 inches. Smaller grinders are more maneuverable in tight spaces, while larger ones offer greater material removal rates. Choose a size that suits the type of work youll be doing. A 4-inch grinder is often ideal for tasks like rust removal and weld cleanup.
Safety Features
Prioritize safety. Look for features like a safety guard to protect against sparks and debris, and a lock-on or lock-off switch for easier and safer operation. Consider grinders with vibration-reducing designs for added comfort during extended use.
Frequently Asked Questions
What are the key advantages of using an air powered angle grinder?
