Product Overview
Heavy-Duty Cutting Power for Industrial Applications
Engineered for extreme material removal in tough environments, the 350MM Laser Welded Wide Cut / Loop Cut Diamond Blade combines rugged laser-welded construction with a specialized undercut segment design to deliver unmatched performance in deep, wide cutting tasks. Available in 6mm, 8mm, 10mm, 12mm thicknesses, this blade is optimized for creating wide kerfs (6-12mm) and loop cuts in concrete, asphalt, reinforced steel, and natural stone. Ideal for industrial saws, excavator-mounted cutters, 20KW Floor saw.
Core Engineering Features
1. Laser-Welded Durability for Heavy Loads
- 100% Industrial Laser Welding: Secures diamond segments to the 350mm steel core with precision heat fusion, creating a bond strength 30% higher than traditional brazing. Eliminates segment loss even under prolonged high-torque operations (max 10,000 RPM).
- Reinforced Core Design: Thickened steel substrate (5mm core) reduces flexing during deep cuts, ensuring straight cutting paths and minimal vibration.
2. Undercut Segments & Segmented Pattern
- Aggressive Undercut Geometry: Deeply recessed segment bases (5mm undercut) increase chip clearance, allowing faster removal of concrete debris, steel shavings, and stone dust. Reduces blade clogging by 40% in wet cutting conditions.
- Alternating Segment Layout: Spaced 8mm apart with staggered heights, the segmented pattern creates a self-sharpening effect. Fresh diamond grit is continuously exposed, maintaining cutting speed through abrasive materials like reinforced concrete (C40/C50 strength).
3. Wide Kerf Capability
- 6-12mm Cutting Thickness Options:
- 6mm/8mm: For precise wide cuts in thin-walled concrete (e.g., precast panels, pipe trenches)
- 10mm/12mm: Ideal for heavy-duty loop cuts in reinforced slabs, asphalt roads, and granite blocks
- Dual-Purpose Design: Switch between “Wide Cut” for material removal and “Loop Cut” for circular/arched cuts without blade changes.

Performance Advantages
✅ Rapid Material Removal: Undercut segments increase chip evacuation rate by 50%, reducing cutting time by 20% vs standard blades
✅ Extended Service Life: Laser-welded segments resist impact damage; 25% longer life in abrasive environments
✅ Safety-Focused Design: Balanced core minimizes kickback risk; segmented pattern reduces heat buildup during wet/dry cutting
✅ Versatile Thickness Range: Single diameter (350mm) with 4 thickness options covers 90% of industrial wide-cut needs
Usage & Maintenance Tips
Cutting Recommendations
- Wet Cutting Only: Always use with water cooling system (5-8L/min flow) to prevent overheating and enhance blade life
- Break-In Procedure: Run at 50% speed for 2 minutes before first use to align segments
- Load Control: Maintain 5-10mm per pass feed rate for 10-12mm thick blades to avoid motor overload
Storage & Care
- Vertical Storage: Hang blades by arbor hole to prevent core warping
- Post-Use Cleaning: Remove concrete/stone residue with wire brush; avoid acidic cleaners
