Dry vs Wet Cutting with 400mm Brazed Diamond Blades — A Practical Guide for Global Project Managers

If you're managing a construction or stone fabrication project overseas, one question keeps coming up: Should I use dry cutting or wet cutting? The answer isn’t just about preference—it’s about maximizing blade life, ensuring safety, and minimizing downtime.

In real-world scenarios, the choice often hinges on site conditions—not just personal preference. For example:

Case Study – Middle East Highway Expansion (UAE):
A contractor in Dubai used dry cutting on granite slabs due to limited water access during summer months. Result? Blade wear increased by 50%, leading to 3 extra blade replacements per week. Switching to wet cutting with a mobile water tank system cut costs by 22% monthly.

The key lies in understanding how brazing affects performance. Unlike sintered blades, brazed diamond segments offer superior thermal conductivity—up to 25% better cooling under load. This makes them ideal for high-speed applications where heat builds quickly, especially in wet environments where consistent water flow is maintained.

But here's what many overlook: even with wet cutting, improper technique can shorten blade life dramatically. Overloading the saw or using low-pressure water jets reduces cooling efficiency by up to 40%. Always ensure:

• Adequate water flow rate (~5–10 L/min for 400mm blades)
• Proper alignment between blade and workpiece
• Use of dust extraction systems when possible—even in wet mode

Let every blade count. Don’t let poor selection lead to unnecessary waste—especially when your project timeline and budget are already tight. Whether you’re working in remote locations like Mongolia or urban centers like Berlin, smart choices now mean fewer interruptions later.

Remember: the best tool isn't always the most expensive—it's the one that fits your job, your environment, and your goals.
