Answer :
Final answer:
The two factors that affect the drilling rate of a hammer drill are speed and pressure. Higher speed and greater pressure result in faster drilling rate.
Explanation:
The two factors that affect the drilling rate of a hammer drill are speed and pressure. Speed refers to how fast the drill bit rotates, and pressure refers to the force applied to the drill bit against the material being drilled. When the speed of the drill is high and there is enough pressure, the drilling rate increases. For example, if you increase the speed of the drill while maintaining a high pressure, you will be able to drill faster.Learn more about hammer drill drilling rate here:
