Best Cordless Rotary Hammer Drill

If you are looking to drill holes into particularly hard materials like concrete, brick or particularly thick masonry, you will almost certainly need to get your hands on a rotary hammer drill. For maximum convenience, a cordless rotary hammer drill is the best way to go. The best cordless rotary hammer drills provide you with high impact performance, while also giving you the freedom to move around your work area without being restricted by a short-length power cable. Need to tackle some demolition work or undertake heavy-duty DIY jobs? Our guide explains the essentials you need to remember when selecting the best cordless rotary hammer drill models.

Rotary Hammer Drills Explained

Just like a conventional hammer drill, a rotary hammer drill utilises a pistol grip and drill bits to provide you with heavy-duty drilling action into hard surfaces. However, rotary hammer drills are the more powerful of than the two. A rotary hammer drill usually features a longer profile than a conventional hammer drill, with the shaft housing a powerful piston that uses compressed air to produce hammering output.

With a rotary hammer drill, the brunt of the hammering force is delivered by the piston, with the rotation providing secondary force. Although rotary hammer drills do not rotate as quickly as standard hammer drills, they do produce a more significant impact, making them ideal for tackling concrete and much more stubborn materials.

Essential Functions

As a minimum, any good rotary hammer drill should provide you with forward and reverse rotational modes. The reverse rotation is important as it will allow you to retrieve the end of the hammer drill from materials once you have drilled into it. Having both a forward and reverse rotational mode also means you can use your hammer drill to add bolts and screws into tough materials. A chisel function is also a good thing to have. This function prevents the drill bit from rotating, allowing you to use the power tool with a selection of different attachments. This dramatically expands your applications.

Vibration Control Features

Although rotary hammer drill bits are designed so that the user does not have to contend with too much vibrational effect, you will still have to deal with excess vibration. Vibration controls are therefore important features to look out for. Basic features like rubber exteriors and padding will mean less vibration finds its way to your hands, allowing you to remain firmly in control of your tool. If you need to use your hammer drill for very long periods of time, vibration control features are essential.

Variable Speed Control

If you want the freedom to be able to use your rotary hammer drill at different speeds, variable speed control is essential. Variable speed control will allow you to make minor adjustments to the rotational speed of your power tool. In most instances, you can make these changes by pressing on a trigger. Ideally, you want to be purchasing rotary hammer drills that include a locking switch, allowing you to maintain your chosen rotation speeds once you have selected them.

Speed Levels & Impact Rating

You also need to pay attention to speed and impact ratings when selecting rotary hammer drills. Speed ratings are defined in rotations per minute, or RPM. When selecting a rotary hammer drill, a lower RPM is the best option. Impact energy ratings are measured in joules. A higher impact energy rating will yield better results for heavy-duty applications.

The Bottom Line

To ensure you have picked the best cordless rotary hammer drill for your needs, you will want to pay attention to battery specifics when selecting a power tool. A higher voltage rating will provide you with a more efficient power tool that can be used at higher settings for longer stretches of time. However, you should consider recharging time when choosing a hammer drill, especially if you need to use your tool for many hours in any given day. If you need a hammer drill that can cope with big jobs, you should focus on impact energy specifics. A slower rotational speed and high impact rate are what you should be looking for.

Multifunctionality is also important when choosing a suitable rotary hammer drill. If you want a power tool that can meet the broadest range of applications, make sure the model you go for provides you with multiple modes of operation. Variable speed control is also important if you intend to work with a variety of materials and need to tackle different drilling depths.
