If you are drilling a very dense material, your standard bit driver may not cut it. Materials such as concrete, tiles, and stone require additional force from the drill bit, and even the most powerful bit driver lacks it. These types of projects require the best cordless hammer drill, which can cut through these hard surfaces.
The best cordless electric hammer drill bits do two things at the same time: they rotate the bit, and a pinion in the bit forces the weight forward and hits the back of the chuck. The force is transmitted to the tip of the drill bit. This force helps the drill bit to chop up small pieces of concrete, stone or brick, and the grooves on the drill bit can remove the generated dust. The following tips on choosing the best cordless hammer drill will help you find the right tool for your project.
Although most of the best hammer drills can perform the dual duties of a standard drill driver, they are not for everyone. Even smaller hammer drills have heavier parts inside, which means they are even heavier than the best cordless drills. They also have much greater torque than light drill rigs, so if you are not familiar with power tools, don’t be surprised by their power.
If you are not drilling into concrete, bricks, stones or masonry, you may not need a cordless hammer drill. You can save some money by using standard drill drivers for most projects. However, if you find yourself mixing concrete or paint frequently, you might think that the extra torque that a hammer drill can provide will help speed up the work.
The following features make some electric drills stand out from the crowd. Understanding how these tools work will help you make an informed decision and determine whether you need one of these torque machines.
Hammer drills are used to drill holes in masonry. Standard drill bits and drill bits hardly scratch the surface of tiles, concrete walkways or stone countertops. These materials are too dense for the cutting edges of standard drill bits. A hammer drill equipped with a masonry bit will easily penetrate these same surfaces: the hammer function drives the tip of the bit into the surface, generating stone chips or concrete dust, and clearing the groove of the bit from the hole.
Remember, you need to use masonry drills to penetrate these surfaces. These drills have wings on the tips to help remove dust, and their tip shapes are slightly different, more like chisels than standard drills. In addition, if you can penetrate the surface of the masonry material, the standard drill bit will dull or crack almost immediately. You can find masonry drills to be purchased separately in such kits.
Brushed motors rely on “old school” technology to produce motors. These motors use “brushes” to power the coils. The coil connected to the shaft starts to rotate, thereby generating power and torque. As far as the motor is concerned, its technical level is relatively low.
Brushless motor technology is more advanced and more efficient. They use sensors and control boards to send current to the coil, which causes the magnet attached to the shaft to rotate. Compared with a brushed motor, this method produces much greater torque and consumes much less battery power.
If you have to drill a lot of holes, then buying a brushless hammer drill may be worth the extra cost. Brushed hammer drills complete the work at a lower price, but may take more time.
Regarding speed, you should look for a drill with a maximum RPM speed of 2,000 or higher. Although you may not need much speed to drill through the masonry material, this speed allows you to use it as a drill bit without drilling concrete and bricks.
Torque is also important because you can use a sturdy hammer drill to screw lag bolts and screws into dense materials to fix concrete anchors, etc. However, many manufacturers no longer use “pounds” as a metric. Instead, they use “unit wattage” or UWO, which is a complex measurement of the power of the drill bit on the chuck. At least 700 UWO drill bits can meet most of your purposes.
Most importantly, hammer drill shoppers should prioritize beats per minute or BPM. This unit of measurement describes the number of times the hammer gear engages the chuck per minute. Hammer drills with a BPM rating of 20,000 to 30,000 are ideal for most drilling situations, although heavy-duty models may offer a lower RPM in exchange for increased torque.
Because the hammer drill generates a lot of torque or UWO, the user needs a way to adjust how much of this torque is transmitted to the fastener. Before drilling the fastener or screwdriver into the material, excessive torque can cause it to break.
To control torque output, manufacturers use adjustable clutches in their drilling rigs. Adjusting the clutch usually requires screwing the collar at the bottom of the chuck to the correct position, although the position always varies from tool to tool and depends on the type of drilling material. For example, dense hardwoods may require higher clutch settings (as long as the fasteners can handle it), while softwoods such as pine require fewer clutches.
Almost all drilling rigs and drilling machines (including light and medium hammer drills) use three-jaw chucks. When you rotate the chucks, they clamp on a round or hexagonal surface. The three-jaw chuck allows you to use a variety of drill bits and driver bits, which is why they are almost universal in drill drivers. They are available in 1/2-inch and 3/8-inch sizes, and larger sizes are heavier.
The rotary hammer uses SDS chuck. The groove shank of these drills can be locked in place. SDS is an innovation in Germany, which stands for “Steck, Dreh, Sitz” or “Insert, Twist, Stay”. These drill bits are different because the electric hammer provides a huge amount of force, so a safer method is needed to secure the drill bit.
The main battery types that come with any cordless power tool are nickel cadmium (NiCd) and lithium ion (Li-ion). Lithium-ion batteries are replacing nickel-cadmium batteries because they are more efficient and have a longer service life during use and throughout their service life. They are also very light, which may be a factor in you already dragging a heavy hammer drill.
The battery life during use is usually measured in ampere hours or Ah. For light drilling rigs, 2.0Ah batteries are more than enough. However, when you hit the masonry hard, you may want the battery to last longer. In this case, look for a battery rated at 3.0Ah or higher.
If needed, a battery with a higher ampere hour rating can be purchased separately. Some manufacturers sell batteries up to 12Ah.
When you buy the best cordless drill that meets your needs, consider using it for the project. This project will have a lot to do with the size and weight of the hammer drill you need.
For example, drilling holes in ceramic wall tiles does not require much torque, speed or BPM. Lightweight, compact, light weight hammer bit weighs about 2 pounds (without battery), can solve the problem. On the other hand, drilling large holes in structural anchors in concrete will require larger and heavier hammer drills, possibly even electric hammers, which weigh up to 8 pounds without batteries.
For most DIY applications, a medium hammer drill is a good choice because it can handle most projects. Although please keep in mind that it will be much heavier than a standard rig (usually twice the weight), so it may not be ideal because it is the only rig in your workshop.
With background knowledge of cordless electric hammer drills, the following product list for drilling holes in hard materials can help you find the right tool for your project.

If you have never used an electric hammer drill before, you may have some questions about an electric drill and how it works. Below you will find some of the most common questions and their answers to help you point you in the right direction.
You can use an electric hammer as a chisel, but you cannot use an electric drill. The rotary hammer has a mode that does not rotate the bit when hammering, so it is very suitable for chiseling.
Yes, although all hammer drills function as drill bit drivers for most projects in the house, they may be too large.
