Corded Drills

Start with the material and the type of work. Impact mode can be useful for brick and similar masonry, while standard drilling is often preferred for controlled, accurate holes. See how to choose an impact drill.

For corded drills, input power helps indicate workload capability, but it should be considered together with RPM, chuck specification and drilling capacity. See how to choose tool power (W).

Rotational speed affects drilling speed and control. Variable speed is useful when working with different materials and drill-bit diameters; see what is rotational speed (RPM) and what is speed control.

Check whether the drill uses a keyed or keyless chuck and the shank-size range it accepts. This directly determines accessory compatibility. See types of chucks and their applications.

Compare not only the stated maximum drilling diameter but also the materials and bit sizes you will actually use. For diameter and length selection, see how to choose drill-bit diameter and length.

Reverse, predictable trigger control and an auxiliary handle can improve handling, but the tool should only be used in operating modes specified by the manufacturer. See how to use a drill safely.

For extended drilling, balance, grip shape, overall weight and vibration control affect comfort and accuracy. Also review tool ergonomics, weight, and safety systems.

Occasional home use and daily intensive work place different demands on service life, duty cycle and tool construction. See differences between professional and household power tools.
