Answer 1

The correct answer is d. reduce overheating in the drill bit.When drilling deep holes, it is important to move the drill and bit up and down frequently. This action serves to reduce overheating in the drill bit. By alternating the direction of the drill bit's movement, the drilling process becomes more efficient and helps to dissipate heat more effectively. This technique prevents the drill bit from overheating and ensures a smoother and more precise drilling process.
