for construction or repair work is hard to imagine without the use of specialized tools - Punch.Hammers are available in three classes: light, medium and heavy.All are equipped with a cartridge with quick tool change system SDS.The Germans say Steck-Dreh-Sitzt in the English version - Special Direct System, - whatever you like.Standard developed by Bosch in the mid-70s of the last century.

Shank SDS - what, how, where

for easy operation, quick change of the working tool, as well as to increase the contact area of ​​the shank of the drill with a cartridge was introduced standard SDS.

Bosch has developed 5 types of shank:

  • SDS - the first representative of its cl
    ass, the shank with two slots;
  • SDS-plus - developed on the basis of SDS and fully compatible with it, supplemented with 2 slots.Shank diameter of 10mm.Used in light punch.The maximum drilling capacity - up to 26mm;
  • SDS-top - reinforced SDS-plus, shank diameter - 14mm.Designed to eliminate the failure drills when drilling large diameter 16-26mm.Requires installation of another cartridge in the punch.
  • SDS-max - the standard for professional heavy hammers.Shank diameter of 18mm.The diameter of the holes - from 20mm.
  • SDS-quick - system, developed in 2008.Applicable only on specialized equipment (several models rotary hammers Bosch).Compatible with the holder for ¼ inch

common and popular got two standards: SDS-plus - for light rotary and SDS-max - Heavy as the most sought after in the construction market.

Classification of tooling for punch

Modern hammer - a multi-purpose tool.It is enough to choose the right accessories and you will be able to perform a wide range of construction, from the removal of the tiles in the bathroom and ending with the extension of the door or window opening.

Most drills on the market operate in three modes:

  • chiselling;
  • drilling;
  • drilling.

Yes, exactly, hammer drilling - called drilling.For each mode of operation is its own accessories.Modern kits for the gun drills and ensure conduct the most basic operations.

Shot mode - the main mode of operation of the tool.Depending on the model of the gun, the forward movement of the piston transfers energy to the hammer mechanism and snap (pneumatic).Some light rotary hammers under the influence of a mechanical system - spring.

hammers from Bosch are also equipped with an additional function of turning chisels at a predetermined angle (46 positions) - vario lock.

Shot mode used:

  • blades;
  • peaks;
  • channel chisel;
  • semicircular chisels;
  • zubchastye incisors;
  • mortar cutters;
  • tamping plate;
  • core board;
  • sledgehammer.

drilling mode is used for drilling holes in concrete, brick and masonry.Simultaneous use of impact and rotational motion allows the rapid destruction of the material in the cutting zone by crushing followed by sample material.Drills are used for such work, called Boers or bits for the Punch.Also in the hammer drilling mode using core bits - for the sample material for the future installation of sockets and switches groups.The length of the drill to punch ranges from 100mm to 1m.

Drilling mode is used for drilling wood, plastic and other soft materials.It is also an easy punch (up to 3 kg) can be used as a screwdriver.

important.Drilling mode without the need to use the strike to certain technical conditions.When working only in rotation hammer must be converted into the rotation mode with a bang, and scroll to idle for the distribution of grease inside the tool.

selection and installation of the Boers to punch

As mentioned earlier, among the 5 standards of Bosch widespread two: SDS-plus - with a diameter of 10mm and the shank SDS-max - with a shank diameter of 18mm.

Accordingly, most of the equipment is carried out under these standards.Of course, it is possible to use a snap-shank SDS-max on light perforator, but it is not advisable due to their low power, which will result in a decrease in tool life.

Choose manufacturer drill to punch

World registered only a dozen (to be precise 14 companies) manufacturers drills for punchers.Thus at one plant can produce several brands.For example, in Germany the plant produces DreBo Werkzengfabrik for Hitachi, AEG, Milwaukee, Wurth.

In this case, the drill can not be doubted.The data brands also successfully produced in China.

If you want to buy the goods produced in Europe, then you need to pay attention to the company's products ALPEN-MAYKESTAG - with one of the leading manufacturers in Europe.Complaint on production of 2 pieces.1 million.The company's plants are located in Austria and Italy, the company's factories in China do not have.

But not all of China of poor quality.Thus, the same Bosch has its factories in China.Products manufactured under the brand Bosch, is no worse than its European counterpart, and in some cases even better.The main thing is to get to the industrial manufacturer, and not amateurish.

intensity discharge sludge

drain sludge - one of the most important properties of the Boers.From the rate of removal of chips directly affects the quality of drilling.For shallow holes (up to 60mm) suitable borax with a little steep helical grooves.For a more intensive drilling is necessary to use a drill with a steep spiral.The disadvantage of this equipment is to reduce the strength of the drill body.

quickly and efficiently discharged sludge auger drills.They are most effective for drilling deep holes.

How to insert a drill chuck in SDS

Installing drill chuck in SDS is not a big deal.

before installing the working tool should ensure serviceability tool, make sure it for any chips and cracks, breaks check whether the rubber anther.It must be cleaned of dust.Then you need to apply grease to the splines of specialized tooling and firmly inserted into the socket punch.

necessary To press until it clicks.Pull the drill itself, if it is not removed, the installation was successful.To overcome the need to replace the drill chuck ring axially towards the drill and pull tool.

Important: In the process of the drill heats up, changing accessories only be wearing gloves to avoid burns.

to increase the line of operation and to prevent accelerated wear of the tool, as well as snap-in, you should always be kept clean, removing excess grease and dust adhering to it.

Faults Hammer chuck

Since punch working in very difficult conditions, damage to it can not be avoided.The most common failure cartridges out punch.Sometimes it can take off from the gun drill, which indicates the wear of the ball or puck cartridge.In this case they must be replaced in accordance with manufacturer's instructions.

Improper operation can break the drill chuck punch.In this case, any two versions of events.

first - remove the sealing washer, plastic holder and stopper.Remove sleeve and ball-lock.The shank of the drill must be free to come out of the gun barrel.

Another option - flattened back of the shank.In this case, it will be necessary to disassemble the whole hammer, to "drown" the drill shank in the bore of the instrument.Independently this procedure can be carried out in the presence of experience or, at least, a detailed scheme disassembly tool.But it is better to entrust this work to professionals.

Important: not to break drill to punch, it is necessary to regularly retrieve, inspect the stem, remove the dust and grease, and apply new grease.

Operation tool, according to the manufacturer's requirements, the tool will provide service for many years.
