Commonly, it is confused on what tool to use when drilling masonry. Both the Rotary Hammer and the Hammer Drill can be one’s best option. Each having a different set of purposes.
Let’s define a Rotary Hammer and a Hammer Drill.
Hammer drills are small and shaped like your household hand drill and made for light work. It is essentially a drill with a ratchet mechanism that vibrates the bit at a high speed chipping away at the masonry substrate.
Much the same way, a Rotary hammer, is a hammer with a larger motor than a drill which beats on the end of the bit in a hammering motion. This hammering action transfers energy from the bit to the hard carbide chipping away at the concrete or stone.
The rotary hammer also has what used to be called a tool bit driver, which rotates the bit while the piston is beating on it. The rotation of the fluted bit pulls the debris out of the hole that the hammer is making.
Rotary Hammer VS Hammer Drill
It all revolves around the purposes.
When to use a Hammer Drill:
* When making small holes, such as 3/8 or smaller
* When masonry is soft, such as mortar, concrete blocks and bricks. (Hammer Drills are not recommended for use with reinforced concrete or stone due to the density of the material)
* For small anchors or injections
When to use a Rotary Hammer:
* dense masonry
* larger projects
* large holes (three inches in diameter)
And we find yet again, size does matter. Rotary hammers are normally much larger tools than hammer drills. As you might guess, they are a lot more expensive too.
In short, the big jobs call for the power of the Rotary Hammers.
