Hammer Drill Information

If you are deciding to buy a hammer drill it is important to pick the right one for the job. Increase your knowledge with our guide to choosing a hammer drill.

There are a lot of different types of hammer drills on the market today so it’s important to match the right drill to the right job.

What is a Hammer Drill?

A hammer drill is similar to a drill / driver but with the add-on of a hammering action. This causes the drill bit to punch in and out rapidly, drastically increasing the force of your drive. This extra action can be used to drive drill bits forward, necessary for jobs where you need to drill into brick, concrete or masonry.

Most hammer drills come with a switch that allows the user to switch between the normal rotary drill, or the rotary-plus-hammer mode. When set to rotary, the hammer drill can be used for the same jobs that a regular drill driver is used for. With the rotary-plus-hammer mode, the hammer drill is set for use on brick or masonry. These power tools are often used by professionals and contractors for jobs such as installing outside units onto brick walls. They can be used at home for a wide range of jobs, such as installing cabinets on masonry, or even just putting up shelves.

AS the hammer drill can do so many different tasks, it may even replace some of your regular power tools at home. The chuck on most hammer drills can hold a wide range of different screwdriver tips and bits, and as we have already seen, the hammer action can be turned on or off. All you have to do when you meet a tricky surface is to switch out the drill bit and turn on the hammer!

The first decision you will need to make is whether you need a cordless or a corded model.

Corded vs Cordless Hammer Drill

The functions of the two types of hammer drill are similar, but they are both optimal in different situations. The main difference between the two types is the amount of power each type will provide. Corded hammer drills tend to have more power, do not need batteries to rely on, and can be more effective for tougher jobs. The corded drill will also usually have a higher rotation speed then a cordless one. A corded drill might have a speed of around 0-3000rpm, whereas a cordless drill might be around 0-1100rpm. This extra power and speed with the corded drill can come in particularly handy for tougher jobs involving masonry, as well as more unconventional jobs such as sanding or polishing, with wire brushes and polishing pads.

Obviously the biggest advantage of the cordless hammer drill is the portability, which can be a big enough factor if you know you will be using it for anything less than masonry, such as steel, plastic or wood.

For heavy duty tasks faced by commercial professionals, a rotary hammer may be required. This is the larger, pneumatic upgrade to the hammer drill. But for more standard use, the compact design and versatility of the hammer drill make is a must-have for the power tool enthusiast and home hobbyist.
