Buying Guide
Pneumatic Angle Grinder Buying Guide
Choosing the right pneumatic angle grinder can significantly improve your grinding and cutting tasks. Heres what to consider:
Power and Air Consumption
Ensure your air compressor can supply sufficient CFM (cubic feet per minute) at the recommended PSI (pounds per square inch) for the grinder. Higher CFM grinders offer faster material removal. Look for tools that operate around 90 PSI.
Size and Disc Diameter
Angle grinders come in various sizes, with common disc diameters being 4 inches, 5 inches, or 7 inches. Smaller grinders are better for intricate work, while larger ones are suited for more extensive material removal. Consider the types of jobs youll be doing before deciding.
Safety Features
Prioritize safety. Look for features like a safety guard to protect against flying debris and a comfortable grip. Some grinders include a lock-on switch, enhancing convenience, while others have a dead-man switch to immediately stop the tool when released.
