Operating rules

Due to violation of the rules for using a puncher, its service life is significantly reduced

That is why it is important to follow all the manufacturer's recommendations for the use of drilling tools. The following rules will help keep the equipment working for years to come.

• In order for the perforator to serve for a long time, it should not be allowed to overheat. In the process of chipping or drilling, it is necessary to pause to cool the engine.
• It is not recommended to drill a deep hole "in one go". It is necessary to stop, pull out the drill and remove construction debris.
• When slitting, do not make a lot of effort, with emphasis pressing on the tool. Such actions will lead to premature failure of the striking mechanism.

The tool should be positioned strictly perpendicular to the base in which you want to make a hole. Even the slightest misalignment causes mechanical damage to the cartridge.
Manufacturers recommend using the grease of the same name, chucks and drill bits.
Regular lubrication of the working parts of the rock drill is a prerequisite

Pay special attention to the shank. And you should also monitor the condition of the anther and brush of the motor - they need to be cleaned (sometimes replaced) when dirty.

Review of the top good rock drills

How to choose?

Correctly selected drilling equipment can facilitate construction and repair work. Before choosing, you should carefully read the technical characteristics of the device. The main one is the maximum impact energy, which determines the performance of the device. The Sturm company produces rock drills with various characteristics, so the consumer has a lot to choose from.

For home use, there is no need to buy productive and powerful devices - the end will not justify the means. In this case, it is best to take a closer look at low-power equipment, the energy of which will not exceed two joules. It will perfectly cope with the tasks of making holes for anchor fasteners or dowels.

Also, the impact frequency is considered an important parameter. This indicator, along with the impact energy, determines the speed of the tool.The more often the piston reciprocates, the less time it will take to make the hole. For short-term work, it is best to select equipment with a horizontally located motor, while vertical models are suitable for long-term slitting or drilling.

The hammer drill may include some important options that will make the job easier for the user.

These include:

• the presence of a limiter for the length of drilling;
• device for smooth switching of speed modes;
• receiver (reverse start of the shaft in the event that the drill gets stuck in the material);
• locking the power button;
• anti-vibration system.

Whether these options are needed or not is up to the buyer

It is important to choose what is really useful, since there is no need to overpay in rubles for those functions that the owner of the equipment will never use

Which is the best perforator to choose, according to the editorial staff of Zuzako

Few people know which hammer drill is best to use for a particular job. Therefore, in order not to buy an ineffective device, follow the advice of professionals and do not forget about our recommendations.

The best model for the house in terms of price / quality ratio

In most cases, quality rock drills are quite expensive. However, if you search, you can find decent options among mid-range devices. According to the Zuzako editors, the best hammer drill in terms of price / quality ratio is DeWALT DCH273N 0. It has an affordable price, an excellent set of functions and good performance characteristics.

Reliable model for professional work

Professional rotary hammers are a separate category of devices. To accomplish the assigned tasks, they must have sufficient power and a large number of additional components. Some manufacturers make models specifically designed for a particular task. They are quite expensive and not everyone can buy them. If we consider more affordable professional models, then the best, in our opinion, is the Makita HR4501C. It has excellent performance and maximum operational reliability.

How to choose

Regardless of the brand, you need to understand what to look for when choosing this technique. Depending on the task, you need to choose the right equipment

Here are the main nuances that you need to know about before buying a chainsaw:

• Professional models are required for stable use. They have a power reserve of about 1,000 hours, and the power is enough to cope with a thick log. They are used in felling, in the construction of log cabins, and so on. Frequent breaks from work are not required.
• Household models are required for intermittent use. It is recommended to operate them no more than 2 hours a day and 20 hours a month. To eliminate engine problems, it is worth interrupting every 15 to 20 minutes.
• Bus length. Ease of use depends on this. Standard tires have a length of 30 - 35 cm. The larger one automatically belongs to the professional class. Less - non-standard, therefore, they are much more expensive.
• Convenience of the handle. It is advisable to choose saws with an anatomical handle to reduce the likelihood of upper limb numbness due to vibration.
• Additional features that improve usability and security.
• Location of the guard. Often it is placed on the handle itself. But for a person with a large brush, this can cause discomfort during work.

How to use the Sturm rotary hammer

Opening a suitcase with a hammer drill, we see that there is from a standard set, a pair of drills and a chisel. If you want to work and drill deep holes, you may need a longer drill bit or an extension bit.

1. Installing the tool in the chuck... The chuck consists of two parts, the first is fixed, and the lower one can be lowered downward with a movement of the hand, insert a drill or chisel into the hole of the chuck, to the end. The grooves on the tool must line up with the tabs in the chuck. To do this, the drill or chisel can be turned by holding the lower part of the chuck in the lowered position.
2. Choosing an operating mode... To do this, press the black part towards the blue arrow and turn the handle, choosing drilling, drilling with chiselling, chiselling, etc. Sometimes with solid bricks or when a part is chipped and the other protrudes, you can simply choose to drill.
3. Choosing the direction of rotation of the tool... By default, everything was set correctly for me, and the orange switch at number 3 was omitted. Otherwise, there would be a reverse.

That's it, the tool is ready to go. Unlike a drill, it is much easier to install a drill here and more reliably.

Review

Actually, I drilled the holes and now I can give my feedback.

1. Initially, there were no attachments in the kit, so I had to buy an extension cord and a crown. The extension cord was knocked out and had to be replaced. In the replacement, the bolt did not hold the drill well, so the drill fell out during the drilling process and fell somewhere in the wall, which left it there. It is good that the drill and the bolt remained from the crown, after being fixed with them, it became much better. The bolt held the drill and did not loosen.
2. Punch handle (under the number 1). In the process of work, the handle spun, especially when the crown clung somewhere. Then I thought that otherwise the hand would have been twisted, and the puncher was spinning like that, but probably the handle could have been fixed.
3. If you will be drilling in a living area, remove everything or cover. There will be a lot of dust.

In general, the perforator coped with the task, pulled out the drilling using an extension cord and a crown, although the hole diameter was only 50 mm, and there are crowns of large diameters.

Output

More complete feedback can be given over time, when the hammer is working. Therefore, I would advise you to rent a tool or rent it, because after work it will just lie there and gather dust. And money for its purchase is not small, from 3200r. puncher, or from 4200r. perforator plus nozzles.

Possible malfunctions

Do Shturm Chainsaws Meet Your Requirements?

Completely there are downsides

There are several common problems when using chainsaws, namely:

1. Stalls at start. Most likely, the problem is in the fuel delivery mechanism.
2. Doesn't start. Possibly the problem is the starter. There may also be a foreign object in the security or fuel supply system.
3. Slipping. The chain needs to be tensioned or replaced.
4. Too loud operation occurs due to a lack of lubricating elements.
5. The tool vibrates violently if the work axis has shifted.
6. Rotation deceleration can occur if air enters the carburetor or fuel compartment.

If you have any problem, you should contact a specialist to diagnose the tool and take the necessary measures to resolve the issue.

Specifications

Rock drills Sturm are available in two versions - with a horizontal engine and vertical. Each of these models has its own characteristics. For example, horizontal (they are also pistol) are distinguished by more convenient operation and less weight. These are budget options designed to solve small household repair tasks.Their disadvantages include weak performance, rapid heating of the engine, which makes it impossible to carry out long-term work.

Vertical rock drills Sturm (drum) - durable and "hardy" equipment designed for heavy work. In comparison with pistol "brothers" such devices are more weighty and productive. They have a better cooling system, thanks to which the engine heats up less intensely when drilling stone or concrete for a long time. The advantages of such models are high power and the ability to withstand heavy loads. The disadvantages include their high cost, as well as large weight and dimensions.

Sturm produces rotary hammers with SDS Plus chucks and SDS Max (Variation of Drill Hold). Most low- and medium-power devices are equipped with the first. This chuck has a shank diameter of 10 mm. This size is enough to install a drill with a diameter of up to 30 millimeters. SDS Max has 18mm shanks. They are designed to accommodate large extended drill bits. In addition, the manufacturer has equipped some models with jaw chucks that are suitable for installing conventional drills.

Sturm rock drills support several working modes.

• Drilling. This mode is used to make holes for dowels in various materials (aerated concrete blocks, brick, foam concrete).
• Drilling with a blow. This mode is necessary for drilling concrete, stone, cast or porcelain stoneware substrates.
• Impact mode. In this case, the device works in a reciprocating rhythm. The chiseling function is needed to chisel walls for wiring or create holes using a flat chisel. But for making deep holes, this mode will not work, as it will lead to jamming of the drill.
