SDS vs Hammer Drill: Which Electric Drill Is Better for Hammering?

Electric drills can make home improvement and building tasks much easier. Hammer and SDS drills are primarily used in masonry applications. They both have advantages. Here is a quick comparison.

Hammer Drills

A hammer drill works with a special clutch that allows for the drill to punch in and out at a certain distance. The hammering action is very fast. Manufacturers measure this hammering action in "blows per minute." Some hammer drills are designed to pulverize concrete or brick, while others are designed for smaller jobs, such as installing pipes or wiring behind walls. If you need to dig through a large wall or into a large section of ground, a hammer drill will suit you best.

SDS Drills

An SDS drill is designed slightly differently. SDS electric drills allow you to place a bit in the shaft of the drill. Instead of the bit locking into place, it can move slightly. This feature makes hammering easier. An SDS drill is best for attaching items to studs or masonry walls. It won't pulverize the material you are hammering.

Both electric drills are good to have. If you are simply needing to attach an electrical box to the outside of a brick home, an SDS drill is best to use. If you need to get behind a wall for something, the hammer drill is the way to go.
