Breakers and Demolition Hammers
Demolition hammers break concrete and masonry by percussion. The catalog spans electric demolition hammers and air-powered pneumatic breakers, the classic tools for slab, foundation, and pavement removal.
Fonctionnement
A motor- or air-driven piston strikes the tool steel hundreds to over a thousand times per minute, and each impact propagates fractures through the material. Impact energy, measured in joules or foot-pounds, separates chipping tools from breakers that split reinforced slabs; the operator's role is guiding, not pushing.
Types et variantes
- Demolition Hammer
- Electric or hydraulic percussion breaker for demolishing concrete and masonry.
- Pneumatic Breaker
- Air-powered paving breaker for heavy demolition of slabs and foundations.
- Hole Saws
- Cylindrical saw bits that cut clean round openings in board, masonry, or metal.
Comment choisir
Material thickness sets tool class: light hammers for tile, overhead, and wall chipping; mid-weight hammers for pads and partitions; and 60-90 lb class breakers for slabs on grade, footings, and pavement. Pneumatic breakers need a compressor sized to their cfm, while electric units trade some power for independence and quieter operation.
