Chuck size / drilling capacity: 10 mm — The defining feature is that the drill’s chuck (the part that holds the bit) grips bits up to 10 mm in diameter.
Motor power & speed (varies by model): Typical models have motors in the range of ~400 W to ~500 W (some heavier-duty versions may go higher).
Rotational speed (no-load RPM): Many 10 mm drills deliver no-load speeds from ~0 to 2800–3300 RPM. This wide speed range (with variable speed control in some) gives flexibility depending on material.
