Impact and hammerless drill: which one to choose?
Before giving preference to one of the tools, it is necessary to have a clear idea of what you are going to choose from. So, on one shelf of the store are percussion drills, on the other. hammerless. And meanwhile, the manufacturer unanimously asserts that their products are the best. How not to be confused in this situation? Knowing the features and advantages of each model will help.
And first of all, in order not to overpay for an unnecessary set of functions, you must determine exactly what tasks will be required from the tool.
While hammerless drills usually drill only metal, wood, plastic, percussion designs will also be useful when the handyman is faced with the task of coping with denser surfaces. A hammer drill can drill through brick, concrete, stone.
An impact drill can boast only two operating modes: drilling, screwdriving and unscrewing. And an impact drill appeals to its versatility, offering another mode that will allow you to cope with the drilling of stronger structures. True, under the intense loads of concrete chiseling that peorators endure, impact drills won’t “live” for long. However, if punching holes in concrete is not needed every day, such a tool will quite help the cause.
The favorite drills in this feature are the impact drills. The spindle of an impact drill is already heavy-duty, so do not expect super-precise results from this model. When choosing a tool, decide for yourself what you can sacrifice. precision or versatility.
Drill vs. Hammer Drill vs. Impact Driver: What Drill Should I Buy
Due to the fact that hammerless drills do not have a percussion mechanism, they are lighter, and therefore more convenient for prolonged work.
Power and speed are the two characteristics that unite both impact and nonimpact drills. When choosing an impact drill, pay attention to the frequency of blows that the model is capable of.
Both types of drills can operate both from the mains and function perfectly from batteries. If you are going to work in a room where there is no outlet or the presence of wires is extremely inconvenient, for example, going to climb to a height, it is unconditionally better to give preference to cordless models. A modern manufacturer guarantees their long service life on a single charge.
And one more step to overcome: decide for yourself if you need a tool for the home or if you are looking for a drill that can easily handle any complex tasks. Models made for professional builders can withstand prolonged extreme loads, while the tool of the home craftsman can boast of a large presence of additional functions and its lightness.
Basic Types and Differences of Drills
Drills are a whole class of devices of different types with different lifespans. They differ in characteristics, cost. Quality and reliability. Knowing the task at hand helps you choose the right tool.
Impact drill. Tool without impact function. Suitable for drilling in metal, wood and plastic. Not suitable for stone, brick or concrete work.
Impact drill. Model with 2 drilling modes. normal and impact. The impact is achieved through the operation of a ratchet mechanism consisting of two gears. Brick, cellular concrete, expanded clay aggregate, fireclay, etc. can be drilled with this model at the expense of the impact function. But not suitable for drilling holes in concrete with granite chips.
Electric screwdriver. Can be used to drill and work with various fasteners (screws, self-tapping screws). An all-purpose option for small household chores and furniture assembly work. All wrench drills are equipped with reversing and torque adjustment. Some of them have LED-lighting of the working area.
Angle drill. A specialist model for work in hard-to-reach places. Has a specific application field. Not suitable as an everyday household tool.
Mixer drill. Powerful hammerless drill. Needed for mixing construction mixtures and drilling large-diameter holes. Most models have no chuck. usually the whisk connects directly to the shaft. Not suitable as an everyday household tool. Used on construction sites to mix plaster, adhesive mixtures and putty.
The mixer drill
Mixers are more general-purpose tools. Their function is not only drilling, but also mixing various construction mixtures. For this reason, most mixer drills are professional tools and are rarely sold for domestic use.
Not really a drill. However, many craftsmen at home for domestic work is purchased cordless drills, so I can not avoid their attention in this article. If the drill’s primary function is to drill precise holes, the geared tool’s function is to demolish. You can easily make a hole in a concrete wall, or use the impact mode to destroy a brick wall or punch a hole for electrical wiring. But it is important to be aware of the fact that a drill is not designed for precise drilling. Trying to make such a hole with a pen can ruin the material and the surface. So wondering what is better to choose a drill or a peorator, realize that these tools are basically different in purpose.
When we have understood the types of drills and their purpose, let’s move on to the main functions and indicators that you need to pay attention to when choosing a drill.
Cordless drill and its advantages
In addition to cordless drills, which need to be plugged in with a cord, manufacturers also produce cordless drills. Such models use their own rechargeable battery as source of energy and do not require constant connection to the mains during operation. It is mobility that is the main advantage of this type of tool.
It is not practical to equip powerful tools with a battery because of the high power consumption, so rechargeable batteries are mainly offered for drills and screwdrivers. They have a small weight, which makes them convenient to use in hard-to-reach places, particularly when assembling furniture.
The main drawback of cordless drills is their limited life. a battery charge lasts for about an hour of intensive use. However, this problem is solvable. it is enough to buy a model with two batteries in the kit or an additional battery. You can use the drill while one is being recharged.
The main features of an impact drill
Among the characteristics to look at when choosing a drill: power, rotational speed and the ability to adjust the speed.
Drill motor power
The motor is the “heart” of our tool. Its power depends on the boundaries of the device. The motor type determines the power, rotational speed and is reflected in the efficiency of the drill.
Small domestic drills with up to 1000 watts power. Whether you have to do the job around the house or in the cottage, the power is just right. They can work 4 hours a day. It is also necessary to take a break every 20 minutes.
Professional drills are equipped with motors with power over 1200 watts. Robust inner and outer components in alloyed steel, rubber, aluminum and other hard materials.
When buying an impact drill for the home, experts recommend focusing on devices from 700 to 1000 watts. This is the kind of tool that can solve all household tasks. They will also suffice for home repair. Do not take the most powerful model for simple jobs, as a more powerful drill will be heavier, and during repair work, even an extra half a kilogram will be a problem.
Turning speed and speed control
No less important in an electric drill is the rotational speed and the number of revolutions. There are drills with the number of revolutions up to 3000. these are models for uncomplicated tasks or processing. Professional equipment may have a higher number of revolutions.
There are also pneumatic drills, which have their own characteristics of work. To connect any pneumatic tool, you need to buy an air compressor.
Main elements of the mechanism
The drill, like other universal mechanisms, is arranged quite simply. Mechanical power is provided by an electric motor, most often. a collector motor. Operating torque is transmitted to the drive pinion. The pinion gear shaft is directly connected to the chuck, where the drill is clamped.
The motor consists of a fixed stator with copper wire coils, a rotor mounted in bearings with copper coils, a collector. a split ring and spring-loaded brushes made of durable graphite.
The stator is made of electrical steel with high magnetic permeability. The rotor is the shaft on which the core is mounted with longitudinal recesses for the windings. The core is also made of electrical steel. Wire coils are placed in the grooves of the core and the ends are attached to the collector. Collector plates through a solid dielectric base are rigidly attached to the shaft. The shaft also has a fan impeller on it; it blows air to cool internal engine parts. Brushes are fixed in special slots and freely pressed against the collector ring; this is how electrical energy is supplied to the rotor coils. Friction against the collector causes the graphite to fray, so the brushes wear out as they are worn out and must be replaced periodically.
Hyundai D 850 impact drill
Hyundai. World famous South Korean company, which is engaged in the production of versatile and multifunctional devices. This drill is designed for frequent or intermittent use in industrial or residential applications. The Hyundai D 850 tops the drill rating, thanks to its high reliability and breakage protection. Drills and chisels. Equipped with a robust and well-protected 850 W motor. Frequency of strokes when chiseling. 45,000 rpm, maximum speed for drilling is 3,000 rpm. Metal chuck design with 13mm diameter was designed to allow easy and reliable percussion operation. Can switch off the hammer mechanism during operation. Drill bit locks securely in place to protect the operator during operation. Reverse rotation is installed, so the drill can also be used as an electric screwdriver. If the drill bit jams, it can easily be pulled out with the reverse. There is also a variable speed function for working with different materials.

How to choose a drill
What is a screw, types of screws
This device is needed when leveling walls, ceilings, floors, foundation devices, when laying tiles, installing windows and doors, for marking walls before painting or wallpapering, as well as other types of construction and repair work. Even installing built-in appliances and laying pipes is impossible without a building level.
Spray gun is a good alternative to brushes and rollers. With the help of this tool it is possible to paint quite a large area. In this case, spray guns can be of several types.
The most popular and proven tool for applying mortars to surfaces are ordinary paint brushes. At the moment there are many kinds of paint brushes, which differ from each other by construction type, material, purpose, etc.д. It is important to note that the choice of this tool should be taken responsibly, because in case of using a low-quality brush the paint substance will be applied to the surface unevenly, bristles may remain, which will spoil the appearance of the painted surface in the end result.
