About these items This electric demolition jack hammer is built for breaking concrete, stone, brick, asphalt, masonry, tile, plaster, and similar hard materials. The 2200W model delivers 1350 BPM with 66J impact energy, while the 2800W model delivers 1200 BPM with 45J per blow, giving users options for different job demands. Both models are suitable for demolition, trenching, chipping, hole breaking, pipe work, plumbing preparation, interior renovation, water supply and drainage projects, and other construction tasks requiring strong impact performance. Each jack hammer includes four chisel types to support multiple applications. The included point chisel is useful for concentrated breaking, the flat chisel helps with general demolition and surface removal, the clay spade supports digging or loosening material, and the scraper or scaling chisel helps remove coatings, tile, plaster, and surface buildup. The chisels are made from alloy steel for strong wear resistance, and the quick clamping design allows fast installation and removal while keeping the bit firmly positioned during operation. The 360° adjustable auxiliary handle helps users adapt to different working angles and body positions. Its rubberized grip improves control and helps absorb vibration during long work sessions. The rear handle is shaped for comfortable holding and helps reduce hand and arm fatigue when breaking dense material. A trigger with lock button supports steadier operation, while the balanced body design helps users maintain better control on demanding surfaces such as reinforced concrete, brick walls, asphalt pavement, and masonry floors. The demolition hammer is designed with a strong metal structure for long-term jobsite use. The 2200W model uses heavy metal construction, while the 2800W model features a one-piece aluminum alloy housing that balances strength and manageable tool weight. Built-in cooling helps reduce motor heat during extended operation, supporting more stable performance. A visible oil port or oil cap access also makes routine maintenance easier, helping users keep the hammer ready for repeated demolition and breaking tasks. Both models come with a blow-molded carry case and practical accessories for transport, storage, and maintenance.
