Rebarbadora a gasolina DEDRA DED8836 3,5 kW disco de 300 mm betão aço

The DEDRA DED8836 petrol cut-off saw delivers 3.5 kW of raw cutting power in a compact, air-cooled 2-stroke package. Unlike benchtop or cordless alternatives, this handheld saw brings industrial cutting capability directly to the workpiece—no power outlets, no battery limits. Its 300 mm blade with 25.4 mm arbor slices through concrete, steel, asphalt, and stone up to 100 mm deep, making it a go-to for demolition, road work, and structural modifications.

Highlights

• 3.5 kW (4.7 HP) 2-stroke engine with forced air cooling for sustained high-load operation
• 300 mm blade diameter with 25.4 mm arbor—compatible with a wide range of professional discs
• 100 mm maximum cutting depth for deep cuts in concrete and steel
• Manual pull start with CDI ignition for reliable firing in all conditions
• 1.3 L fuel tank with 25:1 petrol-to-oil mix ratio for extended runtime
• Lightweight at 10.5 kg net, reducing operator fatigue during vertical or overhead cuts

In daily use

On the job site, the DED8836 proves its worth from the first pull. The 65 cm³ engine spins the blade at up to 4500 RPM no-load, maintaining torque through dense material. The vibration levels of 5.5 m/s² on both handles meet typical professional standards, while the sound pressure of 100 dB(A) demands hearing protection—standard for this class. The saw's balance and 10.5 kg weight allow controlled plunge cuts and straight tracking, even in reinforced concrete. The 1.3 L tank provides enough fuel for multiple cuts before refilling, and the simple 25:1 mix ratio is easy to prepare on site.
