It can be confusing on which to prefer between rotary hammer vs. hammer drill. So to help you decide, I will be providing you with each of their characteristics so you can decide on which one to get.

Rotary Hammer

If you’re looking for something that is powerful, you should opt for a rotary hammer. This is ideal for drilling more large holes or whenever you feel like removing the tiles on the floors or the walls. It is packed with a lot of power because of the large piston that it has

Another good thing about a rotary hammer is that there are models that can produce 30,000 beats every minute. This is common in rotary hammer drills that are high-end. Using a rotary hammer is more comfortable to use since your hand will experience fewer vibrations. It means that your arms and hands won’t experience fatigue.

Hammer Drill
