- Impact drivers look like power drills. But on drills, the only thing that moves is the bit. On an impact drill, a fast-moving hammer continually pounds the bit, letting you ease up on the pressure you would normally have to exert on the drill.
- You can easily screw down boards, planks and other pieces of wood with less effort.
- Different types of bolts and fasteners can be applied with an impact drill.
- Impact drivers are a great help in tight spaces, such as when you're hanging windows and you might not be able to get the leverage you need to exert a great amount of pressure.
- The impact driver is not an end-all. It can be used most successfully for general fastening and up to medium-level construction jobs.
