Answer :
Final answer:
Hammer drills are designed to work when pressure is applied to the drill bit. This characteristic is essential for drilling into hard materials, as the pressure engages the drill's hammering action.
Explanation:
The statement, 'Almost all hammer drills will not work until pressure is put on the drill bit', is generally True. Hammer drills are designed for heavy-duty work where extra force is needed, such as drilling into concrete or other hard materials. The hammering mechanism within the drill is typically activated when a certain level of pressure is applied. Hence, pressure is essential for the tool's operation. This mechanism involves a clutch that engages the hammering action only when the user presses the drill against the material being drilled.
