How To Use A Puncher

Rules for the safe use of the tool

It is permissible to use the puncher only with the use of personal protective equipment. These include safety glasses, headphones, gloves, and a respirator. Clothing should be free of fluttering long-length elements. Hair is gathered under the headdress. Shoes should be dry, comfortable and non-slip, preferably with socks reinforced with metal plates.

The noise level of a working tool fluctuates in the region of 100-110 dB. If the treated surface resonates (for example, a concrete wall), then the noise level can reach 140–150 dB. Such sound loading can lead to medical or mental health problems. Headphones or earplugs must be used.

How to insert / pull out a drill or drill

To work safely with a hammer drill, you need to master a few simple skills. Mandatory skills include installing and removing a drill, drill or any other accessory.

Installation of the working tool

All rotary hammers are equipped with an SDS type chuck that does not require keys. Unlike jaw chucks, drill installation takes seconds:

  • Pull the base of the chuck down.
  • Insert the drill shank into the hole.
  • Release the base of the chuck, the spring will return the chuck to its place, the locking ball mechanism will securely grip the drill in its metal embrace.
  • Check that the drill is securely fastened by pulling it towards you. The cutting tool must not be removed.

A properly installed drill should not protrude more than 1 cm from the socket when trying to pull it out by hand.

If a cam chuck is installed in the hammer drill, the drill can be fixed using the traditional method. by rotating the chuck body around its own axis until the thread is tightened.

Instructions for using the device

Rotary hammers are widely used in modern construction industry, they have replaced monotonous and ineffective manual labor. But its use is fraught with certain risks that you need to be aware of before starting work.

First of all, you need to work with a serviceable tool in a regular mode authorized by the manufacturer. The power supply must be provided through a cable with a cross-section corresponding to the power consumption.

After transporting the rock drill in the cold season, to soften the lubricating fluids inside the mechanism, you must wait at least half an hour.

The operator performing the work must be healthy. Before work, you must study the instructions for the device and safety rules.

The main operating modes of the punch

Perforators operate in several basic modes, switchable by the operator depending on the work being done.


It is performed after switching the regulator to the corresponding mode (drill icon). The overwhelming number of models of rock drills are equipped with a function of a gradual set of revolutions of the working shaft. The speed is controlled using the start button. With a slight pressure, the revolutions from zero smoothly rise higher. When the button is pressed all the way, the revolutions become maximum.

Depending on the material to be drilled, it is recommended to adjust the speed of the drill or drill bit. So, wood products are best drilled at high speeds, metal at low speeds, and concrete or stone at medium.

Most often, a hammer drill is used for drilling stone or concrete. This is due to the fact that the device of the chuck for fastening the drill has a backlash in the longitudinal axis, designed for percussion drilling function. Therefore, when drilling holes in wood or metal, it is not always possible to achieve the desired accuracy. The drill tip may wiggle slightly.

It is recommended to use a chuck with SDS shank for precise drilling of holes. The drill without play is fixed in a chuck, which is inserted into the hammer drill. Jaw chuck included or sold separately. Any holes and materials can be drilled with a replaceable chuck.

Work rules

Before using the rotary hammer, read the attached instructions: this will avoid many errors in operation. Wear safety glasses, ear plugs, gloves. Clothing should be buttoned up to avoid fabric wrap around the drill.

Do not allow the tool to idle, as this leads to premature wear of the mechanisms. If you are working on loose material, it is best to do this in the no-hammer drilling mode to avoid scattering. When working with solid materials, use liquid cooling with special emulsions, grease or machine oil. If you have to drill a hole with a long drill, start with a shorter drill of a suitable size. To extend the life of consumables, periodically let the rock drill cool down and immerse the drill in water or machine oil. During prolonged operation, the gearbox overheats; it is necessary to allow it to cool completely. Alternate between rest and tool work: 30 minutes of work followed by 10 minutes of rest.

How to use a puncher correctly. Operating modes

The vast majority of rock drills have the ability to work in three modes:

Drilling. the toggle switch of the tool is placed opposite the mark in the form of a drill. Then you need to put the drill at the desired point and press the power button. Strong pressing on the punch is not allowed in this mode of operation. When drill chucks are used, the hammer drill position as well as counterclockwise rotation can cause the chuck to break. To prevent such a situation, the tool has an impact blocking function, it is needed for drilling holes in metal and wood. Before switching on the instrument, be sure to check which mode is set on it.

Hammer drilling or drilling. the hammer drill switches to hammer drilling mode (the toggle switch is placed opposite the mark with the hammer and drill). The drill should be positioned where the hole is to be made. During operation, the drill must not be skewed or slipped. The tool is held confidently, with a little pressure on it. Get into a comfortable working position in advance so as not to lose control of the hammer drill when it accidentally bumps into iron reinforcement.

Impact. allows you to perform impact work, chiselling and chiselling. The toggle switch should be above the hammer mark. The tool must be held very firmly, applying some effort so that it does not jump off the right place. No high pressure required.

  • How to choose a puncher
  • What is the difference between a drill and a hammer drill

This tool is used to work on concrete, brick, stone, metal, and is also used as a conventional drill and jackhammer. They can drill any holes, remove old tiles, break through floors or walls. The hammer drill has an impact mechanism. electromechanical or electro-pneumatic action. To turn it on, you need to press the button. The main disadvantage of rotary hammers is their considerable weight: there are specimens weighing more than 25 kg. For the convenience of work, you can attach an additional handle made of soft material, this will reduce the intensity of vibration.

Punch Care

First of all, you need to pay attention to the lubrication. If you have to work on concrete, you should not save on it. Lubricate the cleaned drill shanks periodically with a grease (such as grease). You can protect the tool from a large amount of construction dust with a shield made from the bottom of a plastic bottle. After turning off the punch, wipe it with a damp soft cloth, having previously moistened it with soapy water. Make sure the air vent is completely free of dirt.

If the tool breaks down, you can only entrust its repair to specialists from the service center. If the perforator in use has high power and strong impact, a preventive inspection by a master will be useful. This will avoid malfunctions that could cause injury.

How to work with a punch in different modes.

Punch device. we study the nature of the impact force

The hammer drill device has design features that depend on the engine power and the type of tool assembly. Therefore, before choosing a rock drill, it is better to study it from the engine to the chuck. Having learned all the subtleties of the device, as well as small nuances, you can decide on the model and type.

In what cases can the lights flash?

If the perforator is equipped with light signaling lamps, then their signal may mean a breakdown or malfunction of any unit or mechanism. If the red light on the punch is flashing, refer to the instruction manual of the device.

Deciding which punch is better

The first electric rock drill appeared back in 1932. Since then, its design has remained practically unchanged. The main elements to this day remain: an electric motor, an impact mechanism, a gearbox and a cartridge. Time and progress only increased the electronic musculature, simultaneously replacing the material of the case and mechanisms.

The main function of this device is shock. According to the method of its implementation, there are electromagnetic and pneumatic perforators. Electromagnetic beats are produced by two interacting electric coils. The reciprocating motion from the coils is transmitted to the core, which in turn acts on the drill. In pneumatic devices, a push occurs when the piston moves back and forth in the cylinder. Household rock drill, as a rule, is equipped with a pneumatic impact mechanism.

By the type of drive, the following devices are distinguished:

  • Electrical network (powered by the electrical network);
  • Electric rechargeable batteries (battery operated);
  • Pneumatic (used in fire and explosive works);
  • Gasoline (used in road construction).

The most widespread is the electric network type with a pneumatic mechanism, it is also called a household puncher.

The number of modes is distinguished:

  • Single-mode, only drilling mode is present;
  • Dual mode, drilling mode and hammer drilling mode;
  • Three-mode, have a drilling mode, drilling with a break, a chiseling mode.

Additional tool features

In addition to the above, the standard set of options in a modern rock drill include:

  • Ruler for determining the depth of the hole;
  • Lever for fixing the operating position of the start button;
  • Safety clutch. stops the motor when the drill gets jammed.

And also in the design of each device there are systems:

  • Dust removal. impeller on the engine with a system of dust extraction ducts;
  • Vibration damping. special springs between the body and the power unit;
  • Electronic regulation of operation and monitoring of the condition of brushes on the collector of the electric motor.

An important rule, non-observance of which can lead to failure of the hammer drill. Switching modes should be carried out only when the tool is completely stopped.
