hammer drill
Quick Summary
A hammer drill is a percussion tool used for drilling into hard materials like rock and concrete. It combines the action of a hammer with a drill bit, delivering rapid, forceful blows to break through tough surfaces.12
This type of drill is a specific kind of pneumatic hammer, meaning it's powered by compressed air. Unlike a standard drill, the hammer drill's head is designed to strike the material repeatedly, making it effective for tasks where significant force is needed, such as in construction or mining.21
