Every man's arsenal should have tools for all occasions. A hammer drill, unlike a drill, allows you to quickly and effortlessly drill even the most difficult materials, such as concrete or brick. Therefore, together with a hammer drill, even major repair work in an apartment or in the country will become simple and easy.

Rotary hammer or hammer drill?

Many have a tool kit at home, which includes a pair of adjustable wrenches and wrenches, a drill, and a screwdriver. A drill is a very light tool, the main task of which is drilling. Drilling, not drilling (that is, a small range of motion) only allows you to drill a hole. This option is suitable for working with soft materials such as wood or fiberboard.

Drilling with a drill can cause a lot of hassle: often the hole begins to crumble, and sometimes, due to the great efforts applied to the tool, the drills break and remain in the wall. In addition, the hammer drill produces a backward motion, which creates vibration and very strong kickback. This often leads to slipping of the drill from the drilling site and damage to the drilled surface.

The main function of the hammer drill is chiselling . The range of motion and permeability are greater here, which means that drilling is better and faster. In addition to this, there is a function to turn off the rotation of the chuck, that is, the drill does not rotate, but only makes translational movements. This makes it easy to punch wiring trenches or remove unnecessary tiles and plaster from the walls. A drill for such actions is categorically not suitable.

Features of brand models

Rotary hammers of the P. I. T. company occupy one of the leading lines in the rating of power tools. Since 2012, the company has been using the technology of pouring the anchor with a compound, which prevents the accumulation of debris and dust inside the tool. Thanks to the high-strength light-alloy metals, the P. I. T. is also lighter than its competitors.

The brand's rock drills fall into two categories: vertical and horizontal. Let's consider each group in more detail.

Vertical

These rock drills are characterized by a vertical engine arrangement. In another way, they are also called rotary hammers with an L-shaped engine. Such a unit is heavier, more difficult to operate, requires more careful maintenance (frequent and abundant lubrication of the mechanism parts is required).

Such devices are loved by professional builders, as they are more reliable with prolonged use . In addition, the L-motor has the highest torque, and thanks to the air-cooled tool, the tool does not overheat under prolonged use. Most often, such tools are used for vertical drilling, that is, floors, ceilings. The mass of the entire unit is directed to one side, so drilling is easier and faster.

The cons of a vertical rock drill are negligible. Since these are mostly professional tools, they do not have a drilling function. In fact, there is no need for it, because builders use different tools for each type of work. The overestimated cost is also understandable - everything that is intended to perform a large amount of work will be heavier and more massive for a long time. Consequently, such models are more reliable and more expensive.

The P. I. T. vertical perforators include models RVN32-C2 and RVN26-C3. RVN32-C2 - seven-kilogram instrument with three modes. Suitable for wood, stone and steel. Power - 1500 W, and the maximum frequency of beats per minute - 4350. The noise level does not exceed 93 dB. РВН26-С3 already weighs less (about 6 kg). It also has three modes and is suitable for the same types of surfaces. Its power is less - 1200 W, and the maximum impact frequency is almost equal to the previous model and amounts to 4250. The noise level is 91 dB.

Horizontal

These rock drills have a motor located parallel to the drilling axis. This category includes all household (household) models. They do not have such high power, they are lighter, easier to operate and maintain. They are ideal for installing facades, drywall, and in general everything related to vertical installation. The main disadvantage of such models is the lack of cooling elements. Initially, such tools were not intended for long-term, but only for small household chores, so overheating was not expected. With prolonged use, be sure to make sure that the mechanism does not overheat, turn it off in time and let it cool down.

RVN20-D, RVN20-C, RVN24-D, RVN24-C1, RVN24-C, RVN26-C2, RVN26-C3, RVN28-C1, RVN28-C, RVN32-C2 - models of horizontal perforators from P. I. T . All of them have a case, lubricant, limiter, and an additional very ergonomic handle, thanks to which horizontal drilling becomes easier. RVN20-D, RVN20-C - the very first, simple and lightweight perforators in the line. Modification D differs from C by the force of impact and the maximum number of revolutions per minute, and the force is greater in modification D, and the rpm - in C. The average cost of models is from 2,500 rubles.

The difference between RVN24-C, RVN24-C1, RVN24-D is also small . The latest modification has a wider set: this is not only a case and grease, but also 4 drills of various configurations. The average price is 3500 rubles. In addition to the RVN26-C2, RVN26-C3 models, there are also C1, C4 and C5, but they are not as popular as the first two modifications. These instruments are already more like professional-amateur. They have increased indicators of weight, impact energy and power. The price for them is correspondingly higher. The set includes drills and chisels.

RVN28-S and RVN28-S1 are exactly the same models . The difference lies only in the greater perfection of the C1 model in terms of power consumption, speed and impact energy. If the RVN28-S costs about 3000 rubles, then the improved one is a thousand rubles more expensive. RVN32-C2 - the "coolest" and most professional model in the line of rotary hammers.

Due to its greater weight (up to 8 kilograms), there is a vibration damping function. This is the only P. I. T. professional rock drill with a horizontal motor.

Customer feedback suggests that Chinese manufacturing isn't always bad. The tools of this brand are of high quality and serve their owners for many years. Breakdowns do occur, but primarily due to improper storage or use.

Terms of use

• Check the power supplies, they should be 220 V.
• Make sure the instrument is turned off before plugging it in. Otherwise, the unit will start to spin spontaneously - this is dangerous.
• Insert the drill bit, fasten it securely.
• Before starting work, make sure that there are no exposed electrical cables, pipes or other obstructions nearby.

If you are using an extension cord, check the cross-sectional cable and make sure that no strangers are near the extension cord during operation.
