SANG New V-Slot Diamond Blade for Cutting Reinforced Concrete, Concrete, Brick, Stone
Quick Answer
SANG's Turbo V-Slot Laser Welded Diamond Blade is designed for fast dry cutting of concrete, brick, masonry and selected reinforced-concrete applications.Its V-slot turbo segment helps improve debris evacuation and airflow around the cutting zone, while laser welding provides a strong segment-to-core connection. The range covers five common diameters from 115 mm to 230 mm, making it suitable for different handheld cutting requirements.
For professional buyers, however, blade selection should not be based only on purchase price. The more meaningful indicators are:
Cutting speed + blade life + safety + consistency + cost per meter.
1. What Makes a Turbo V-Slot Diamond Blade Different?
A diamond blade mainly consists of a steel core and diamond segments. The segment geometry and bond formulation determine how efficiently diamonds cut and how quickly worn diamonds are released.
SANG's Turbo V-Slot design uses an open turbo profile with V-shaped slots. This structure is intended to support:
- Faster debris evacuation
- Better airflow
- Reduced cutting-zone clogging
- Efficient dry cutting
- Stable cutting performance
Laser welding is another important feature. Compared with conventional joining methods, laser welding creates a strong connection between the diamond segment and steel core, making it particularly suitable for demanding professional cutting applications.

3. Which Diameter Should You Choose?
Size
Recommended Applications
115 mm
Brick, masonry, shallow concrete cuts and repair work
125 mm
General construction, brick, block and concrete
150 mm
Medium-depth masonry and concrete cutting
180 mm
Larger openings and deeper concrete/masonry cuts
230 mm
Heavy-duty handheld concrete and masonry cutting
The correct size depends on the required cutting depth and machine specifications. A larger blade does not automatically mean faster cutting.

If speed and dry cutting are priorities, a Turbo V-Slot blade can be a strong option. If ultra-clean edge quality is the priority, a continuous-rim blade may be more suitable.
5. Can It Cut Reinforced Concrete?
Yes, but application conditions matter.
The blade can be used for selected reinforced-concrete applications, especially where reinforcement is limited. For heavily reinforced structural concrete, contractors should normally consider dedicated reinforced-concrete blades, wall saws, floor saws or other higher-powered systems.
Blade selection should consider:
- Concrete strength
- Aggregate hardness
- Reinforcement density
- Cutting depth
- Machine power
- Required cutting speed
6. Dry Cutting Does Not Mean Dust-Free Cutting
Concrete, brick and masonry cutting can generate respirable crystalline silica dust.
Therefore, professional dry cutting should be combined with appropriate dust-control measures, such as:
- On-tool dust extraction
- Industrial vacuum systems
- Suitable respiratory protection
- Jobsite isolation where necessary
- Compliance with local safety regulations
The U.S. OSHA and UK HSE both identify concrete and masonry cutting as activities requiring effective silica exposure controls.
7. Real Jobsite Case
In a Middle Eastern residential renovation project, SANG reports that a contractor needed to cut openings in hollow concrete block walls where water use was restricted.
The contractor changed from a conventional brazed 230 mm blade to a SANG Turbo V-Slot laser-welded blade.
According to the supplier-reported project data:
- Blade life increased from approximately 8–10 openings to about 41 openings
- Cutting time was reduced from approximately 9 minutes to less than 6 minutes per opening
- No segment loss was reported during the 60-apartment project
These figures are field data reported by SANG rather than independent laboratory results, so actual performance will vary with material, machine, operator and cutting conditions.
8. What Should Procurement Managers Compare?
Do not compare diamond blades only by unit price.
