The Yato YT-827722 brushless rotary hammer belongs to the GRF series and is designed for professional assembly and construction work. Powered by an 18 V Li-Ion battery system, it combines drilling, impact drilling, chiseling, and chisel positioning in one compact tool.
Its brushless motor ensures stable power and durability, even during prolonged use. The efficient impact mechanism delivers 2.5 J of energy with an impact frequency of up to 5000 min⁻¹, enabling fast progress in concrete, brick, and stone. The SDS-Plus tool holder allows quick accessory changes, while the LED work area lighting improves visibility in dark spaces.
With a maximum drilling diameter of 22 mm in concrete, electronic speed adjustment (0–1400 min⁻¹), and rotation direction switch, the tool offers precision and control. Lightweight at only 2 kg, it reduces operator fatigue during overhead or serial drilling tasks. The set includes two 4 Ah batteries, a charger, an additional handle, and a depth limiter for enhanced accuracy.
