Which Punch To Choose For Work

How to choose a hammer drill for personal use? Nowadays, buying a branded drilling tool is not a problem, but how to choose the right hammer drill for yourself and your tasks? Explore the punch device and specifications.

How to choose a hammer drill for personal use?

which punch to choose for work

Choosing the right drilling tool means making home repairs easier for a long time. How can you successfully choose a puncher in order not to overpay for the brand and get high-quality equipment?

Several decades ago, only powerful electric drills equipped with drills for metal and concrete were used in everyday life. A truly branded, specialized tool was sold only abroad; it was impossible to just go to a construction supermarket and choose a suitable device.

Punch device and characteristics

All punchers are divided into three types in terms of functionality:

  1. Single-mode. Impact drilling function only. Most often, such perforators are not used in everyday life, but are used as professional additional equipment for narrow purposes.
  2. Dual mode. Hammer drilling plus classic drilling or chiseling only.
  3. Three-mode. The tool is equipped with all the functions specified in paragraphs 1 and 2.

The choice of a hammer drill is based primarily on the characteristics of power and impact force. The higher these indicators, the better the hammer to be fitted.

Types of working chuck for rock drill:

  • Usual;
  • Quick-clamping.

Which drill chuck to choose? For household or household chores, the keyless quick-release model is best suited. Changing the nozzle in this version is convenient, easy and quick.

Rock drill classification by weight:

  1. Lungs. Up to 4 kilograms. Power is no more than 700 watts. Only available with SDS-plus chuck for 26 mm drill bits.
  2. Average. 4 to 8 kilograms. Power from 700 to 1500 watts. Depending on the equipment, both SDS-plus and SDS-max are equipped.
  3. Heavy. than 8 kilograms. Power is over 1500 watts. Equipped only with SDS-max chuck for diameter up to 60 mm.

What is the difference between a drill and a hammer drill and vice versa

The hammer drill is characterized by a longitudinal axial movement of the working part, similar to an impact drill. Therefore, hammer drills are confused with a heavy drill. In words, there is practically no difference, however, the hammer drill functions on the basis of pneumatics, and any impact (heavy) drill works thanks to mechanics.

Hence the difference in surface speed. Pneumatic drilling of holes in concrete, brick and stone walls reduces physical stress on the user. For any hammer drill, similar work is associated with great fatigue, and the hammer drilling mode wears out the internal components of the drill very quickly.

We come to the conclusion that the hammer drill should be larger and more massive than a drill with an impact function.

Energy and frequency of impacts

For a hammer drill, the impact function, measured in joules, is very important. The performance of the device, as well as the diameter of the hole to be machined, depends on the impact energy. For daily work with a hammer drill, this is one of the most important indicators.

It is essential that the hammer drill at the maximum will very quickly deplete its resource, and with the hammer drill they perform this work for a long time without wear, especially with the single-mode model.

It turns out that energy and frequency determine the level of performance. When choosing a perforator on your own, you need to evaluate the amount of work on chiselling, then, according to the specified characteristics of the impact frequency, calculate the approximate productivity.

How to choose a hammer drill for work and home

When performing repairs, it is often necessary to drill through and blind holes in surfaces of increased strength. In this case, a perforator is used for concrete, brickwork or natural stone, which allows you to make holes using an impact mechanism.

Food type

When deciding which perforator to choose for the home, you need to have a clear idea of ​​what types of repair work will be performed and in what conditions.

Rotary hammers by type of power supply can be:

  • Electric;
  • Pneumatic;
  • Gasoline.

In a domestic environment, electric rock drills are used in most cases, which are:

  • Network;
  • Rechargeable.

The mains tool is powered from a conventional electrical network, rechargeable from batteries (lithium-ion, nickel-cadmium or nickel-metal hydride). If it is possible to connect to an outlet, choose a power electric punch, paying attention to the length of the power cord (the longer the better). And if there is no network connectivity, then a standalone cordless rotary hammer is the best solution, but it costs much more and is used much less often.

Technical specifications

The basic technical parameter of a hammer drill is power, the more powerful the tool, the wider and deeper holes can be made in surfaces.

Tip. Do not purchase hammer drills below 600W.

Remember. Power does not affect tool performance. The diameter and length of the hole, a number of other characteristics of the punch depends on this parameter.

The second important parameter is weight, we distinguish three groups of perforators:

  • Lungs (less than 3.00 kilograms);
  • Medium (from 3.00 to 8.00 kilograms);
  • Heavy (from 8.00 kilograms).

The third parameter is the impact energy (force) in Joules, which is in direct direct proportion to the power.

Other parameters also affect performance, including:

  • Impact frequency (from 2150.00 to 5800.00 beats / min);
  • Rotation speed (from 230.00 to 2300.00 rpm).

They, like the force of impact, depend on power.

An inexpensive perforator will have a rotation speed of 1000.001500.00 rpm and a blow rate of 4000.004500.00 beats / min, this is quite enough.

What are the punches

In the modern repair and construction market there are many options for electrical devices for construction purposes from different manufacturing companies. How Do I Pick a Good Rotary Hammer? This question is most likely fundamental to you. First, you need to decide on the type of device, because all devices are of two types:

  • Professional;
  • Domestic.

You should not immediately make a choice in favor of the household option if you decide to purchase a hammer drill for your home. Which unit to choose is not an easy question, because it is worth considering all the subtleties of the purchase.

So, both models are different from each other, since they have different degrees of stress. At the same time, both the household and the professional model have many functions. It is worth mentioning here that construction and home repairmen essentially perform the same function, so there is no need to purchase a more expensive model to improve the quality of repairs.

We advise you to evaluate the advantages of household power tools, since you can choose a hammer drill for household work based on its power, ease of use and the number of the most necessary functions for repair. This will be quite enough for high-quality repairs in the house.

The best hammer drill models

Those users who have experience in the construction industry are sure to have favorites among modern manufacturers. We tried to single out two main brands that are distinguished by high quality production and are in great demand in the construction market in our country, these are Bosch and Hitachi. Which is better to choose: Bosch or Hitachi? Which hammer drill is the most suitable for home use? In order to answer this question, it is worth considering the functionality of each model.

So what makes Bosch special:

  • The motor power is 780 W, and the impact force is 2.8 J. This is quite enough for interaction with solid materials. Therefore, if you do not know which perforator to choose for concrete, you can safely purchase this model;
  • There are special pads on the handle of the model, which allow you to reduce the force of impact during use and make your work more comfortable;
  • The speed of revolutions reaches 3000 per minute;

The model can be used to create holes for the socket and to prepare any kind of mortar.

Now let’s look at the advantages of Hitachi:

  • The power of the power tool is 1200 W;
  • The frequency of revolutions per minute can be from 120 to 250, depending on the type of construction process;
  • For the convenience and safety of the user, the device has a special safety clutch and aluminum protection of the gearbox, which will remove heat;
  • The maximum diameter of holes that the tool can make is from 45 to 125 mm.

Compare all of the above characteristics before choosing a hammer drill. For concrete as well as interactions with hard metals, both are excellent options.

What to look for when choosing a device

There are many aspects to consider before choosing a hammer drill for your home. Feedback from friends and acquaintances in this case is not always appropriate, since there may be completely different aspects in your construction work. The hammer drill must be judged solely on its quality characteristics, as well as suitability for use at home.

So, before buying a device, you should pay attention to indicators such as:

  • Power. In modern models of such power tools, it ranges from 450 to 2000 watts. Before choosing the right hammer drill for your home, evaluate the degree of upcoming construction work and, if you decide that the best device for you is a household type, then feel free to purchase a model with a power of 900 W;
  • Device type. Models are horizontal and vertical. In the first case, the electric motor is located parallel to the impact axis, in the second, perpendicular. Horizontal models are more suitable for domestic use, since they are somewhat narrower and longer than vertical ones;
  • Impact strength. This indicator determines the interaction of the device with the working surface. Simply put, the speed of use and its effectiveness depend on it. Here it is worth paying attention to the power, since this indicator will help you to choose the right puncher. For home use, the model with an impact force of up to 4.5 J is optimal;
  • Number of modes. In modern models, there are such modes of operation as drilling, hammer drilling and hammering. The three-mode option is the most optimal for both domestic and professional use;
  • Cartridge type. On modern models, the most common cartridges are SDS and SDS max. For domestic use, the SDS version with 15 mm drills is most suitable;
  • Model weight. The time of work with the tool depends on this indicator. The optimal variant of the model for home use weighs from 2.6 to 3.3 kg.

When purchasing additional important accessories for the model, pay attention to such a detail as a drill. How to choose a drill for a rock drill in such a way that it is most effective? First, determine the option of the diameter and length of the part you need (they are individual for each device). The shape of the cutting surface is another important feature. The best borax for use are those models that keep evenly in the channel and do not jump to the side.
