Best hammer drill

 

What are the best hammer drills in 2018?

 

If you’re looking for the best rotary hammer out there but don’t have the time to go through our tips and reviews, then we’ll tell you right from the start that the Makita HR2475 is the model we found to be the best appreciated. While not particularly powerful with a 7 Amp motor, this unit is highly efficient, designed to deliver the greatest amount of force for the least amount of energy used. Furthermore, its is remarkably durable thanks to its elongated brushes and a torque limiting clutch, which disengages gears to prevent overwork if the bit happens to bend. Somewhat unusual for a rotary hammer, it offers great versatility with three operation settings: drilling; drilling+hammering, and hammering only. If the convenience and affordability of a quality hammer drill are what you’re after, then our recommendation goes to the DeWalt DW511.

 

Buying guide

 

The first thing to consider when shopping for a good hammer drill is the kind of use it will most commonly see, as there’s hardly a “best hammer drill” to choose from, but rather models that are most suited for the task you have in mind. Probably the most important element of distinction between what’s currently available on the market is the system used for the hammering action, and these fall into two types.

 

 

The piston hammer drill

 

Also called a rotary hammer, this type of drill uses a powerful gas piston to beat away at hard material while the spinning action clears away the surface layer. While not as powerful as a pneumatic hammer, these are generally used for heavy-duty jobs, which involve drilling holes through concrete or cement for plumbing or electrical cables.

Since these are expected to work under heavy load, it is especially important for rotary hammers to have some features that would extend the life of their various components, such as extra-long brushes or automatic clutch disconnectors, which separate the bearings if the unit is working under too high a load.

Expectedly, these are not exactly light, and the addition of a gas piston makes them long and cumbersome. Furthermore, a lot of the cheaper models don’t offer much versatility, lacking in a drill only setting which will allow them to be used effectively on wood or steel.

 

 

The disk hammer drill

 

Simply referred to as a “hammer drill” in most online hammer drill reviews, this system employs two overlapping discs, one static, and one moving, that are covered in ridges. The hammering action is achieved by the ridges on the two surfaces pushing each other away while rotating under pressure.

An obvious problem with this is that the disks will invariably wear out with use, although very tough materials are employed for their construction. The hammer drill is not intended to be used under the same demanding conditions as the rotary hammer, and despite being significantly cheaper, it might prove to be poor value for professional contractors.

Nevertheless, even a cheap hammer drill might provide great service around the house, especially as they are fairly easy to handle.

 

 

Other things to consider

 

A multiple speed gearbox, either adjusted by a knob or from the trigger, is a good thing to have for better control of the machine when drilling on various surfaces. There is a small downside to this, as the extra gears will provide additional things to break or wear down. Also, the best single speed hammer drills do offer variable speed settings although to a more limited degree.

 

 

Our recommendations

 

With the wide array of options available, it can be a chore to choose the right power tool for your needs. To come to your aid, we’ve looked through some reviews of hammer drills and picked up some of the most popular models available for sale.

 

 

Makita HR2475

 

A spinning hammer is supposed to handle some tough tasks, but luckily, there’s little doubt regarding reliability when it comes to Makita.

Their HR2475 model has extra long brushes so that they wear slower, and a feature that decouples the transmission gears when the chuck encounters too much resistance.

A lot of thought has been put into the efficiency as well, with the proprietary Makita Motor Advantage, that assures optimum energy transfer to the drilling bit by employing interlocking steel laminations, dual armature for the ball bearings and extra copper commuter bars.

Makita also boasts that by carefully synchronizing the hammering and rotating action, this machine completes a job 50% faster than most other units out there.

Considering the overwhelmingly positive reviews this received, the manufacturer’s claim appears to be truthful.

Somewhat unusual for an item in its category, the HR2475 also allows for a great degree of versatility, with a variable speed trigger control and three operation settings, that will allow it to be used as a basic drill, as a hammer drill for masonry, and as a simple hammer for breaking tile.

DeWalt DW511

 

With a 7.8 Amp motor, this DeWalt unit is a little more powerful than the Makita, but this doesn’t mean it will be as well suited for heavy-duty tasks.

It uses a disk system for the hammer, which allows it to be light and fairly compact, and at only 4.3 lbs in weight coupled with a variable speed trigger, it should be a breeze to handle even by the most inexperienced handyman.

The front grip also rotates to 360 degrees, so it provides good ergonomy from every position.

At a maximum wattage out of 650 W, the chuck can go from 0-2,700 RPM under no load, and it can generate as much as 46,000 BPM (beats per minute) when in use, which will be enough for light concrete, wood, and steel.

Durability-wise, this comes with an overload-protected motor, like many of the more expensive DeWalt models, and people who’ve used it found it can take a lot of beating for the price.

Skil 6445-04

 

Since DeWalt isn’t in the best circumstances a purely budget solution, we’ve included this small and convenient hammer drill from Skil for those that don’t expect to put their power tools through much use.

It has basically the same functionality as a name brand model and can work with a wide variety of bits, up to ½ inch in diameter for drilling small holes through masonry.

With no load, its 7.0 Amp motor can achieve 3000 RPM, which would make it effective for every drilling task around the house.

This will allow you to use it as a regular drill without worrying that the hammer disks — the most sensitive part on this type of drills — will wear out and need replacing.

Other than that, it’s light, compact, and reported to be easy to handle, with a variable speed trigger but only two speeds, a regular forward and reverse.
