About hammer drills

A hammer drill, sometimes called a rotary hammer, is a powerful tool that is used for drilling holes in hard surfaces such as concrete, brick, and stone. It is used in construction, renovation, and DIY projects. The hammer action of the drill is what sets it apart from regular drills, and it can be essential for certain applications. In this blog, we will discuss how a hammer drill works, why the impact action of a hammer drill is important, when and when not to use it. Additionally, we will explore common applications and review what you’ll need to get started.

Drilling masonry and concrete products requires some special tools and accessories. When drilling concrete, brick or block, we’re dealing with a lot of aggregate, sand and gravel, held together with Portland cement. To cut through this material we need to use a pounding or hammering motion as well as a rotary motion. This pounding motion splits apart the grains of sand and aggregate, and the rotary motion of the drill drags the material up out of the hole.
