By visiting this website, you probably know what a cordless drill is. But what everybody doesn’t know, is that some cordless drills have a hammer function, and what exactly a hammer function is. In this article, I will walk you through the term hammer drill,where and when we use it, and I will reveal for you what my favorite hammer drill is.
So…What Exactly Is a Hammer Drill?
A hammer drill is a drill that has the ability to provide a short, rapid hammer thrust so that the material is pulverized. The mission of the hammer drill is to drill quicker with less effort. The hammer drill has a specially designed clutch that not only spins the drill bit(like a conventional cordless drill) but also punches the drill horizontally and vertically in small motions at the same time.The stroke of each punch isn`t much and the power isn`t great. The reason why the hammer drill pulverizes the material is because of the speed. You have thousands of BPM (blows per minute) that together with the rotating motions of the drill that cause the material to crack faster than with a conventional cordless drill. Most hammer drills has a switch that allows you to turn of the hammer function so that you can use the cordless drill on more conventional tasks like driving screws.
Where Is It Suitable To Use a Cordless Hammer Drill?
Typical tasks for a hammer drill is concrete, masonry or bricks.Everybody that have done some drilling in thick concrete knows that a good hammer drill is essential.Of course, you have some powerful conventional drills, but regardless, the horizontally and vertically motion together with the rotary motion, makes the drilling real smooth and easy with the hammer drill.There is no point using your hammer drill in woods or metal, as you can`t pulverize those materials.In fact you can end up hurting your self, damage the drill bit and the material you are drilling in. The hammer drill is for brittle materials only.
What Drill Bits To Use With a Hammer Drill?
As the drill bits gets exposed to a lot of punching and rough treatment we need to be sure that the drill bits can handle it. The tip needs to be some kind of hard material. Most drill bits for hammer drilling have a tungsten-carbide tip. I personally have the Neiko 12-Piece SDS Hammer Drill Bits with tungsten carbide tip, which I am really happy with.It contains most of the commonly used bits.
