Rotary hammer sds max 20j 1400w (YT-82131)

Sds max 20j 1300w 7kg impact hammer

A very powerful combi type impact hammer. Ideal for installers for serial drilling for electrical boxes, drilling for cables and pipes, and installation penetrations in walls when laying cable routes or installing air conditioning and ventilation.

• Sensitive
• Powerful hammer
  • A sensitive safety clutch protects the tool and operator when the drill bit is jammed in reinforced concrete
  • large power and matching high RPM significantly speed up work. /strong>speed up the work considerably
  • audar 20 J and frequency 2900 strokes/min . strong>enable very efficient forging in hard concrete and reinforced concrete (high-frequency vibrations crush the material the fastest)
  • fast drilling with SDS-max impact crowns up to 150 mm in diameter and spiral drills up to 50 mm in diameter (no jamming of the drill spiral even with large quantities of material)
  • infinitely variable speed and frequency control
  • the motor positioned vertically is more resistant to vibrations generated by the electropneumatic mechanism acting along the tool axis
  • optimal position of the center of gravity and thelow weight of 7 kg in relation to high power
  • precise SDS-max chuck fits chisels of other brands
  • anti-vibration handle provides comfort
  • copper insulated winding
  • packaged in a durable carrying case 
  .

  High power

  20J obtained through the large diameter of the piston and 1300W commutator motor made of copper (rotor + stator) means faster work speed and less user fatigue.

  Longevity

  The quality of the seals in the impact mechanism allows for continuous operation. The hammer can be used in serious work, i.e. wherever the work cycle requires forging for 3 - 4 h.

  The hammer also has a high-quality tool holder that does not jam chisels.

  Convenience of use

  With its vertical motor and short hammer body, the center of gravity is centrally located. This provides perfect balance and does not tire the operator.

  The hammer also has very good power-to-weight ratio.

  The short body of the hammer makes it possible to change positions frequently, making cracking concrete much faster. Concrete is less strong in tension than in compression, so you have to forge at different angles still looking for the weakest points in the structure you are dismantling. Therefore, a short body and the lowest weight are strategically important.

  Benefits of Yato impact hammer:

  • very powerful percussion
  • perfectly-fitted housing
  • building lubrication system with sealed mechanism
  • high quality tool holder: easy to pull out the chisel even after prolonged work
  • mild clutch, making it safe for the operator
