The YT-82138 Petrol Rotary Hammer delivers 30–35 J single stroke energy and up to 45 J impact force, making it capable of drilling through granite and the hardest concrete faster than electric-powered devices. Its high power (1.3 kW, 51.7 cc engine) significantly reduces working time for demanding tasks such as installing light poles, traffic lights, energy barriers, road signs, radio masts, and sliding gates.
Weighing only 11 kg, it is ergonomically balanced for easier demolition of walls and ceilings, with reduced operator fatigue. The hammer offers two operating modes—forging (hammer symbol) and impact drilling (drill + hammer symbol)—which can be selected easily using the dial with lock button.
The SDS-MAX tool holder (30 mm) ensures compatibility with chisels, blades, peavey, TCT spiral, and crown bits. Powered by a two-stroke engine (95PB gasoline/oil ratio 25:1), the YT-82138 combines portability with durability.
The YT-82138 comes equipped with:
- Complete set of wrenches for servicing
- Fuel mixing tank
