Rotary hammer sds max 20j 1300w 7kg

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

• the sensitive safety clutch protects the tool and the operator when the drill bit jams in reinforced concrete
• high power and high speed matched to it significantly accelerate work
• impact of 20 J and frequency of 2900 beats/min allows for very efficient chiseling in hard concrete and reinforced concrete (high-frequency vibrations crush the material the fastest)
• fast drilling with SDS-max impact crowns up to a diameter of 150 mm and twist drills up to 50 mm (without the effect of jamming the drill spiral even with a large amount of excavated material)
• smooth regulation of rotational speed and frequency
• the motor placed vertically is more resistant to vibrations generated by the electro-pneumatic mechanism, acting along the axis of the tool
• optimal position of the center of gravity and low weight of 7 kg in relation to high power
• precision SDS-max chuck fits other brands of chisels
• anti-vibration handle ensures the comfort of work
• copper insulated winding
• packed in a durable suitcase

High Power

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

Durability

The quality of the seals in the hammer mechanism enables continuous operation. The hammer can be used in serious work, i.e. wherever the work cycle requires chiseling for 3 – 4 hours.

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

Ease of Use

Thanks to the vertical motor and short hammer body, the center of gravity is centrally located. This ensures perfect balance and does not tire the operator.

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

The short body of the hammer allows frequent changes of position, thanks to which concrete chipping is much faster. Concrete is less resistant to tension than compression, so you have to hammer at different angles, constantly looking for the weakest points of the dismantled structure. Therefore, a short body and the lowest weight are strategically important.

Advantages

• very strong stroke
• perfectly matched housing
• construction of a lubrication system with a sealed mechanism
• high-quality tool holder: easy to pull out the chisel even after prolonged use
• soft clutch, thanks to which it is safe for the operator
