A hydraulic breaker wide chisel (also known as a wide flat chisel or spade tool) is a specialized attachment used with hydraulic breakers to break, split, or cut through tough materials such as concrete, rock, or asphalt. Unlike a pointed chisel, the wide chisel has a broad, flat working end designed for surface demolition and precision material removal.
- Design:The chisel blade is wide and flat with a straight or slightly curved edge. The shank is cylindrical or hexagonal body that fits into the hydraulic breaker; designed for tight tolerance and secure fit. Tapered neck transitions the impact energy from the shank to the wide blade and helps focus force efficiently while reducing stress concentration.
- Applications:
- Primary Uses: Surface scaling of concrete and rock; Asphalt cutting and removal; Frozen ground penetration; Layer-by-layer demolition; Brick or masonry wall stripping
- Industries: Construction and civil engineering; Roadworks and highway maintenance; quarrying and mining; Demolition
- Materials:Base material is alloy steel for excellent impact resistance and wear properties. The entire body is heat-treated for core toughness and surface hardness.
- Configurations:
- Head: Cross or Parallel
- Machine Type: SB52, SB102, SB150/sB152, SB200/SB202, SB302/SBU340, SB450/SB452
