12V Mini Cordless Angle Grinder Kit with Batteries & Charger

It can comfortably cut thin to medium metal (up to about 3–6 mm steel sheet/pipe depending on disc type and technique). Users report good performance on thin metal bars, small pipes, sheet metal, angle iron and exhaust parts. For thicker metal (>8 mm) or hardened steel, it will take significantly longer, overheat faster or struggle—better suited for light fabrication, car repair and hobby work than heavy industrial cutting. Always use appropriate cutting discs and apply steady, light pressure.

Yes, it can cut ceramic tiles, thin stone slabs and similar materials when equipped with a diamond cutting disc (not included). It performs well for small tile trimming, notch cutting and light stone shaping in home renovation or DIY projects. For thick stone, large tiles or continuous professional tile work, a dedicated wet saw or larger grinder is recommended. Use light pressure, appropriate disc and safety gear to avoid chipping or overheating.

Each 1300mAh battery provides approximately 20–40 minutes of continuous runtime depending on load (light polishing ≈ longer; heavy cutting ≈ shorter). With 2 batteries included, you get extended sessions by swapping. Charging takes about 3–4 hours. Real-world use shows 4–8 small-to-medium jobs (e.g., cutting several pipes, polishing panels) per charge pair. For longer or heavy tasks, keep batteries charged and avoid deep discharge.

It is not designed for heavy-duty, continuous professional construction site use. This mini 12V grinder excels at light-to-medium DIY, home repair, car/motorcycle work, small fabrication and occasional tasks. For daily long-hour professional grinding, thick material or demanding site conditions, a larger corded or higher-voltage (18V/20V+) heavy-duty grinder is more appropriate due to better endurance, power and heat management. Ideal as a portable secondary tool rather than primary site equipment.
