Makita Hammer Drill Buying Guide
What is a hammer drill?
A rotary hammer (also known as a hammer drill) is a type of power tool which creates a hammering action to penetrate the drill into certain objects with ease. The hammering motion of this tool creates a rapid thrust to pulverize any delicate (and not so delicate) material to drill through without requiring too much force from the operator or damage your tools. If you have ever tried to drill a hole through tough material using a normal screwdriver drill then you will know it is physically difficult as well as unforgiving on the tool.
The way in which hammer drills work is the same technological concept used in other power tools such as the demolition hammer, chipping guns, and breakers. The hammer drill is also referred to as “roto-drill” and “hammering drill” and either come as corded or cordless. Typically corded models are bulkier with a bigger motor in order to produce more power. On the other hand, cordless hammer drills are more compact and lightweight with a smaller motor.
Over the years, cordless drills have been much less powerful than a corded hammer drill for this reason. However, as technology develops the cordless hammer drills are closing this gap and are becoming increasingly popular for contractors.
History of the Hammer Drill
The origin of the hammering drill is a matter of debate. The Fein Company in Germany has patented the “Bohrmaschine mit elektro-pneumatischem Schlagwerk” and sold it to the public in 1914.
On the other hand, Hilti made the Hilti TE 17 in 1967 which is dubbed as the “first electro-pneumatic hammer”. Whilst the Milwaukee Electric Tool Corporation claims that they have made the same kind of tool (a 1/4 inch electrical powered cam action hammer drill) and have been selling it since 1935.
The Bosch Company which is a reputable electronics company in Germany also invented their version of the rotary hammer called the “Bosch-Hammer” and was mass-produced around 1932.
All of these major power tool manufacturers like to claim that they are the original inventors of the hammer drill, mostly due to marketing reasons. But in honesty, who invented the hammer drill first really depends on what you define as a hammer drill. Over the years there is a range of different designs and technology used in order to make their hammer drill work.
What are the different types of Hammer Drill?
Basically, from all of the old designs, there are 2 types of premium hammer drills which are commonly used by everybody. This is because it is simply the best technology in order to get a lot of concentrated power in one place. These two hammer drill designs are the ‘Cam-Action (percussion)’ and the ‘Electro-pneumatic’. Below we have outlined the key points of both of these hammer drill technologies to help you choose which is best for you.
Cam-Action can also be referred to as a percussion hammering mechanism. This concept works with 2 sets of toothed gears which interact with each other to create a hammering action while the drill rotates. Specifically, the chuck mechanism (chuck and bit) moves forward and backwards whilst it rotates at the same time. Cam-Action rotary hammering drills can be used with or without the hammering motion.
But, it is not possible to use it with only the hammering motion as the rotation of the “cams” causes the drill to pound. Cam-Action hammer drills are often built for lower power units. So they are not recommended to be used for heavy-duty construction drilling, only the occasional drilling of concrete and other hard-surfaced materials.
Electro-pneumatic hammer drills are often reserved for bigger and more advanced power units. Often called “rotary hammers”, they utilize a kind of technology called the electro-pneumatic hammering mechanism to pulverize tougher surfaces with a bigger impact force. The piston and the hammer of the tool do not actually touch. But the “EP” chamber creates air pressure which then initiates the transfer of stronger and more efficient hammering energy, as compared to the cam-action counterparts.
The majority of the rotary hammers (as well as electric powered chipping guns and jackhammers used today) are manufactured using this kind of technology. They are preferred for use in industrial work as modern units allow their hammer and rotation mechanism to be used as separate modes or combined. When the hammer mode function of the tool is used, the electro-pneumatic hammering drill can be used as a jackhammer tool, which is great if you only need one now and again.
What are the main uses of the Hammer Drill?
The clutch component of the hammering drill is specifically designed to spin the drill bit while simultaneously hammering it along the bit’s axis with an ‘in and out’ motion at the same time. The actual distance where the bit travels and the force of the blows exerted are relatively small and the hammering action happens very fast that it creates a thousand blow per minute (BPM) or 1,000 impacts per minute (IPM).
Although the distance is quite small, the repeated blows created by the tool are good enough to break up hard surfaces such as cement or brick as the spiral flutes of the drill bit whisk all the debris away. This makes the rotary hammer a more favourable tool compared to a regular drill. This is because it has the capacity to drill through concrete faster and with less physical force exerted. Moreover, it is also the tool of choice for creating holes for anchors bolts, wall plugs, and concrete screws.
Almost all hammer drills have a button or switch to turn on or turn off the special “hammer clutch” function when needed. This will enable its user to utilize the tool for fragile materials such as wood or metal. There is no denying that rotary hammers are more expensive and bulkier than conventional hand drills, but they are more preferred to be used in applications where quick drilling is required.
Makita Hammer Drill Safety Features
At Wonkee Donkee, personal safety whilst using any power tool is of the utmost importance. In this next section, we outline the main key safety points that you need to know before using a hammer drill.
Read the User’s Manual before using the tool for the first time in actual drilling applications. Use appropriate safety equipment such as safety gloves and goggles to avoid your hands from being injured as well as preventing the concrete chips or debris to enter your eyes.
Try to determine if the model of the drill is appropriate for the project you are going to do. Hence, the capacity of the battery matters. The battery of a cordless rotary hammer often comes in 6 volts to 36 volts. The more voltage you have, the more capable is the tool for completing any kind of job you can think of. Using a weaker tool to complete a heavy-duty task can be dangerous as you can cause damage to yourself or the power drill in the process.
Both types of hammering drills follow the same principle for drilling holes in stones and masonry. They are also used for creating holes in concrete footings, where concrete wall forms are usually pinned. Other than that, they can also drill holes to concrete surfaces so that wall framings can be attached.
Larger units of rotary hammers are also utilized for doweling as well as creating holes through masonry walls and other concrete surfaces. The hammering motion of the tool helps break up the concrete so that it can be easily removed by the drill bit’s flutes while initiating the drilling process.
