Buying Guide: Stone-Friendly Angle Grinder Purchases
What level of power do I need for stone work? For cutting and heavy grinding on stone, a grinder with at least 7.5 amps or a powerful 18V+ cordless system is recommended. Higher RPM helps with faster material removal, but ensure you choose compatible discs to avoid overheating.
Corded vs cordless: Corded models provide consistent power for longer sessions; cordless units offer mobility for on-site stone jobs. Consider battery capacity and the availability of fast chargers for longer projects.
What disc type matters for stone? Diamond blades and diamond cup wheels are typically best for stone and concrete work. Ensure you have the correct blade size and arbor compatibility for your grinder model.
Safety considerations: Use eye protection, gloves, and a dust mask. Grind or cut with steady control; use clamps or a stable work surface to avoid kickback. Consider water cooling where appropriate to reduce dust and heat buildup on stone.
Ergonomics and handling: Choose a model with a comfortable grip and vibration-reducing features if you plan extended use. A spindle lock facilitates quick blade changes, saving time on the job site.
