DINGQI 101231 – 2300W Angle Grinder
9″ / 230mm heavy-duty grinder for cutting, grinding & polishing steel, stone, concrete.
The Dingqi 101231 is a 2300W professional angle grinder with 230mm disc capacity. Built for metal fabricators, masons, and contractors doing heavy cutting and grinding. This is Dingqi’s flagship big grinder.
Why contractors choose the 101231:
2300W motor: Serious power for 9″ discs. Cuts rebar, I-beams, granite, and thick steel plate without stalling. Much stronger than 1200W 5″ grinders.
230mm / 9″ disc: Large cutting depth ∼65mm. Fewer passes on thick material. Standard for steel work and masonry.
6500 RPM no-load: High speed for fast cutting and smooth grinding. Electronic constant speed keeps RPM under load.
Soft start: Motor ramps up slowly. Reduces kickback on startup and prevents breaker trips. Safer for big discs.
Spindle lock: Quick disc changes with included spanner. M14 spindle fits all standard 9″ discs.
Side handle 3-position: Mount left, right, or top for control. Anti-vibration rubber grip reduces fatigue.
Safety guard: Adjustable tool-free guard. Rotates for cutting or grinding angles.

- Check RPM rating: Use discs rated ≥6500 RPM only
- Let grinder reach full speed before cutting
- Never use damaged discs — they can explode
