Correct water flow at the kerf extends diamond blade life and keeps silica dust below exposure limits.
Wet cutting is standard practice for diamond blades on concrete, stone, and asphalt. Insufficient water flow causes segment overheating, premature bond wear, and unsafe silica dust levels. Protec Tools recommends minimum flow rates based on blade diameter and cutting depth.
Flow Rate Guidelines
- Hand-held saws: continuous stream directed at kerf contact point.
- Walk-behind saws: minimum 2 liters per minute per inch of blade diameter.
- Core drills: steady flow through center feed and outer flush ports.
Setup Checklist
- Verify pump output before starting production cutting shift.
- Clear slurry from trench to maintain water reach at kerf.
- Inspect hoses and fittings for leaks that reduce effective flow.
- Document flow checks in job site safety log.
Protec Tools technical team advises on wet cutting setup for contractor fleet operations.
