Which of the following hand-operated drilling machines is used for drilling small diameter holes up to 6 mm?
A bevel gear type hand drilling machine is specifically designed for light-duty work, particularly for drilling small diameter holes (generally up to 6 mm). It operates using a hand crank mechanism where bevel gears transmit motion from the handle to the drill spindle, allowing smooth rotation and better control. Because of its compact design and manual operation, it is ideal for precision work on thin materials or soft metals where small holes are required.
