Supplier's Category: All Waterjet Cutting: Cold cutting of metals, stone, and composites with abrasive water streams
Waterjet cutting uses a high-pressure abrasive water stream to cut metals, stone, and composites without heat, avoiding the heat-affected zone that laser or plasma cutting can leave. It handles thicker material and a wider range of substrates than laser cutting, at slower speed.
Waterjet’s main advantage over laser is cutting thick or heat-sensitive material without a heat-affected zone, so it’s worth specifying when that matters, not as a default.
- Confirm whether your material or thickness actually needs waterjet, versus a faster laser cut
- Ask about achievable tolerance and edge taper at your material thickness
- Check nesting/material utilization practices if cost per part matters at volume

Where waterjet is the right choice
Waterjet gets specified where material or thickness rules out laser or plasma cutting.
- Thick metal plate: structural components beyond laser’s practical thickness range
- Heat-sensitive materials: composites, certain plastics, hardened metals that laser would damage
- Stone and glass: architectural and specialty cutting
