How to choose the right angle grinder
Disc Diameter
115–125 mm discs suit most cutting and grinding tasks on metal and masonry. Larger 180–230 mm models offer deeper cuts and higher material removal rates for heavy construction work.
Corded vs Cordless
Corded models deliver continuous power at lower weight. Cordless grinders — such as the Makita 18V and 40V XGT range — give full freedom of movement on site, especially where access to mains power is limited.
Input Power & Idle Speed
Higher wattage handles denser materials without bogging down. Idle speed (RPM) determines cutting aggression: up to 11,000 RPM for general use; lower RPM models with adjustable speed are safer for polishing and fine work.
Adjustable Speed & Safety
Variable-speed grinders let you match the speed to the disc type and material. Look for anti-vibration handles, restart protection and kickback detection — standard on professional-grade Bosch and Metabo models.

Disc compatibility tip: Always match the disc's maximum RPM rating to your grinder's no-load speed. Using an under-rated disc at high RPM is a safety hazard. Check the spindle thread size (M10, M14) before ordering replacement or cutting discs.
Frequently asked questions
What size angle grinder do I need for cutting metal?
A 125 mm (5-inch) angle grinder is the most versatile choice for cutting steel, stainless and aluminium. It balances power and manageability. For deeper cuts in thick steel sections, a 230 mm model provides more depth.
How long does a cordless angle grinder battery last?
Runtime depends on the battery capacity and workload. A Makita or DeWALT 5.0 Ah battery typically delivers 15–30 minutes of continuous grinding on mild steel. Carrying a spare battery ensures uninterrupted site work.
Can I use an angle grinder for polishing and sanding?
Yes — with the correct backing pad and abrasive disc. Use a model with adjustable speed (variable speed control) set to a low RPM to avoid overheating the workpiece or the polishing pad. Fein and Metabo offer purpose-built variable-speed grinders for finishing work.
