This 2200W demolition jack hammer delivers up to 1350 BPM for effortless concrete, brick, and stone breaking. It includes four chisel bits – pointed, flat, clay spade, and scraping – for versatile applications. The secure bit locking system prevents accidental dislodging during use. A self-lock switch reduces operator fatigue, while the 360° rotating auxiliary handle allows for comfortable operation from any position. The external oil port simplifies lubrication; the unit is pre-oiled for 20-30 hours of initial use before requiring a one-third capacity refill. Constructed with durable metal, this jackhammer is designed for long-lasting performance. Included chisel bits are crafted from heat-treated alloy steel for enhanced durability and efficiency. The 360° rotary handle features a slip-proof rubber grip to minimize vibration and maximize control. The D-shaped rear handle further reduces muscle fatigue. A visible oil port allows for easy maintenance, and the cooling system ensures optimal operating temperature. This jackhammer is ideal for demolition, trenching, chipping, breaking holes in concrete, block, brick, tile, and stucco; suitable for plumbing, mechanical installation, construction, and interior decoration projects.
