Demolition and breaker hammers thrust their chisel at high impact to chip, break, cut, and scrape concrete, masonry, brick, asphalt, and tile. They are dedicated chiseling tools that produce a hammering action for jobs requiring more impact energy than rotary hammers. Their impact energy increases as the tool's weight class increases, with demo hammers performing lighter, targeted chiseling and breakers delivering stronger blows. Corded hammers allow long run times for repetitive tasks, maintain full power during operation, and have no batteries to recharge. Cordless hammers operate in areas without access to wired power, eliminate the tripping hazard of a cord, and run on brand-specific batteries.
