Core Advantages
Patented Great Wall Tooth Geometry: Broad tooth grooves enable fast chip evacuation to prevent clogging and cut down cutting resistance.
Complete Size Selection: Six standard diameters (φ100–φ230) ensure compatibility with handheld and benchtop cutting devices for flexible selection.
Robust Vacuum-Brazed Diamond Coating: Firmly anchored diamond grit resists high-temperature shedding, delivering superior wear resistance and extended service life versus conventional sintered discs.
Premium Cutting Finish: Burr-free, chip-resistant cuts minimize subsequent finishing labor.
Vibration Suppression: Uniform tooth layout stabilizes rotation, mitigating operator fatigue and machine abrasion.
Broad Applicability: Adaptable to bulk industrial cutting as well as casual repair tasks, supporting both dry and wet cutting operations.

Usage Notes：
Equipment Installation & Speed Check
Confirm the blade’s outer diameter and bore fit your machine parameters strictly. Never run the tool over the blade’s rated speed, and firmly fix spacers and flange nuts during installation to avoid wobbling.
Personal Safety Protection
Always wear safety goggles, dust masks, heavy-duty gloves and workwear. Keep other personnel away from the area of flying cutting debris.
Standard Cutting Operation
Feed materials at a stable pace. Do not press hard, conduct curved cuts or side grinding, which may lead to blade cracking and tooth shedding.
Storage & Pre-use Inspection
Store blades in cool, dry places away from corrosive materials. Check for cracks, deformation or missing teeth before use; replace defective blades immediately.
Working Environment Requirement
Do not operate in flammable or explosive environments to avoid fire risks caused by high-temperature cutting scraps.
