So, while shopping for a new cordless drill at the hardware store, you come across a few nearly identical models. The main difference between the two is that one is referred to as a hammer drill or, to be more accurate, a hammer drill driver.
A detailed examination of the drill vs. hammer drill comparison indicates that these two devices are similar. Except for the internal hammering system, this instrument differs from a drill. It might justify your desire to pay a little bit more for it.
Most manufacturers begin with a drill driver and add a hammer mechanism behind the chuck to create a hammer drill. Typically, it increases the total length slightly and the weight by a few ounces. As a result, you might not even be able to distinguish between the two when comparing them.
There are clutch settings and drill settings on modern drills and hammer drills. In addition, a hammer drill has an additional hammer mode that you can select.
Some types separate the clutch collar from the mode changes, while others keep them all on the same collar. In any case, the drill mode is usually immediately adjacent to the hammer mode. The clutch, modes, and gearbox are still mechanical switches and collars on the head, even on hammer drills with electronic settings.

The hammer mechanism introduces a forward and backward chipping motion akin to that of a rotary hammer. That action can occur more than 30,000 times per minute in the greatest hammer drills!
When drilling a hole in masonry or concrete, it is advisable to activate the hammer mechanism. Without it, drilling cannot proceed effectively. On average, hammer drills run 25% faster. A test with a Milwaukee M18 Fuel hammer drill and 1/4-inch multipurpose drill bits took roughly 8.5 seconds to drill to the target depth in regular drill mode. It took only approximately 6.5 seconds to switch it to hammer drill mode. It might not seem like much to lose 2 seconds. However, it makes a significant impact when you use larger bits or when you need to drill numerous holes.
When you drill in hammer mode, the sound will be noticeably different. Along with the sound of the bit, the hammer mechanism also makes a sharp buzzing sound.
Never use a hammer to drill through wood, metal, plastic, or other substances. In some materials, the chipping motion does not facilitate faster drilling. Instead, it can sometimes slow you down and vibrate the experience.
CONCLUSION
Most hammer drills costs more than drill driver models. Even though you might not
drill through concretevery often, it's a useful
power toolfor the occasions you do. Given that there isn't a size or weight penalty (anymore), we advise you to spend a little more money on it.
