I'm trying to understand how the DCH133B rotary hammer stacks up against the DCD1007B hammer drill. I did some research online, but I'm still unclear on the main differences. What should I know about how a rotary hammer differs from a hammer drill, especially in their use for drilling into masonry?

Great question! Basically, a hammer drill is like the underdog for smaller jobs. It vibrates and uses a quick, light hammering action to get through materials like masonry, but it’s not super fast for tougher jobs. On the other hand, a rotary hammer delivers a punch with a lot more force, making it way faster for drilling into concrete. So if you plan to do a lot of masonry work, the DCH133B is the way to go as it comes with SDS bits that can handle heavy impact better.
To break it down simply: rotary hammers like the DCH133 have a strong mechanism for impact that makes drilling through masonry feel like a breeze. Plus, they can also chip, making them versatile. In contrast, hammer drills like the DCD1007B use standard bits and are more suited for lighter jobs. They can drill into masonry but aren’t as effective for larger holes. If you’ll be drilling ¾" holes or more, definitely consider the rotary hammer.
Here's the scoop: rotary hammers have a piston mechanism for impact, while hammer drills use a simpler system that doesn’t produce as much power. If it’s tough materials like concrete you’re working with, you’ll want the rotary hammer every time; however, hammer drills are easier to handle and fine for smaller masonry tasks. It really depends on what kind of projects you’re looking to tackle!
