What is the purpose of the handle on a drill?

The primary function of the handle on a drill is to provide comfort and grip when using the tool. A well-designed handle allows users to maintain control over the drill, particularly during prolonged use or when applying significant pressure. Comfort is crucial as it helps reduce fatigue, enabling the user to work more effectively and safely. A good grip prevents slippage, which can lead to inaccuracies in drilling or even potential accidents.

In contrast, the other options suggest functions that are not typically associated with the handle of a drill. Controlling the speed of rotation, for instance, is usually managed through a trigger mechanism or a speed control dial, rather than the handle itself. Noise reduction may come from advanced motor technology or sound-dampening materials, but not from the handle's design. Lastly, while balance can be influenced by the design of the drill as a whole, the handle's primary role is not to keep the drill balanced but rather to ensure a secure and comfortable grip during operation.
