What Is A Hammer Drill? And Why Should You “Cut The Cord”?

That’s a great question. I am glad you are looking for the fabled answer to this all too commonly asked question of “what is a hammer drill”!

Let me ask you this…have you ever seen construction workers working on your local roads with a big old “jack hammer” hammering away at a sidewalk or a driveway? If you have, well then that will help you understand the premise behind the hammer drill. Why and how it works.

Let’s head over to Wikipedia and see what they have to say for “What is a hammer drill”…”A hammer drill, also known as a “rotary hammer”, “roto-drill” or “hammering drill”, (see also rotary drill) is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort. These tools are usually electrically powered, and increasingly powered by batteries. The same technology is also used in electric “demolition hammers”, also known as “chipping guns” or “breakers”.

With that being said, I will be concentrating on “cordless hammer drills”. It wasn’t long ago that you had to use a “corded” drill to provide the power and torque needed for hammer drilling. Cordless drill technology just wasn’t here yet, but alas the cordless hammer drill’s time has come and in a huge way, you would be silly to even own a corded unless you are doing heavy industrial construction highway road work construction.

Today I will be concentrating on the top 5 cordless hammer drills available on the market today as I have researched. With so many manufacturers to choose from, I have based my reviews on…

  1. Performance
  2. Ergonomics/Ease of use
  3. Features
  4. Price
  5. User feedback and reviews
