DeWalt DCD775B vs DeWalt DCD776

A hammer drill contains a hammer clutch or a hammer-like mechanism which provides a circular rotation and a forward driving force. A hammer drill is capable of performing heavy-duty tasks, but it can also be used as a regular power drill.

A reversible drill can alter its rotations from a clockwise direction to a counter clockwise direction, a feature that makes it suitable for both drilling and driving.

The height represents the vertical dimension of the product.

Cordless tools/machines are suited to a variety of different situations, as you are not limited to only working in places with power sources nearby.

A drill with a pistol grip handle is usually compact and lightweight, making the tool suitable for a large variety of apps and easy to use.

The width represents the horizontal dimension of the product.

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

The time it takes to fully charge the battery.

Drills with LED light provide a constant light source.

The chuck holds the drill bits or other rotary tools and its diameter determines the types of bits and tools that the drill can use. A larger chuck is compatible with a wider range of bits and tools.

A keyless chuck drill enables you to change out drill bits rapidly without having to use any special keys.

Pin chucks are designed to hold small bits (less than 1 mm in diameter) that cannot be held securely in a normal drill chuck.

High-precision chucks use ball thrust bearings to reduce friction in the closing mechanism and maximize drilling torque.

A tool/machine with a higher voltage produces more power.

Higher speeds work better for drilling holes in certain types of material, such as steel, aluminium, concrete, etc. The drill speed is measured in rotations per minute (rpm) when the drill has no-load.

A drill with variable speed allows you to switch between low and high speeds, giving you the possibility to take on a wider range of tasks.

The amperage is the strength of an electric current, and it is measured in amperes (amps).

The hammering action provides short, rapid hammer thrusts that make drilling faster and easier. The hammering action is measured in blows/beats per minute (bpm) when the drill has no-load.
