Product Description
Product Introduction
Continuous Rim Segment is whole part segment, usually used in the area where fine grinding is needed, or soft concrete that doesn't want leave much scratches. The cup wheel is available in 125mm and 180mm two diameters, diamond grit sizes ranges from 30/40 up to 120/140.
Designed for concrete leveling applications, this diamond cup wheel excels at transforming rough, uneven concrete surfaces into perfectly smooth, level floors. The continuous rim design ensures consistent contact with the surface, eliminating the skip patterns and uneven grinding that plague lesser tools. Multiple ventilation holes in the steel body enhance cooling during operation while efficiently clearing concrete dust and debris from your work area.
This concrete grinding disc attaches easily to standard angle grinders and specialized concrete preparation equipment. The arrow indicator on the cup ensures proper installation direction for maximum efficiency. Whether you're preparing concrete floors for polishing, removing surface imperfections, or creating the perfect substrate for coatings, this cup wheel delivers professional results every time.
Key Benefits:
- Perfect Surface Leveling - Continuous rim design eliminates track marks and produces exceptionally smooth surfaces
- Extended Tool Life - Strategic cooling holes prevent overheating and extend diamond segment longevity
- Dust Reduction - Specialized airflow pattern minimizes airborne particles during grinding operations
- Time Efficiency - Removes material faster than standard cup wheels, reducing project completion time
- Versatile Application - Works effectively on concrete of varying hardness and age
- Reduced Operator Fatigue - Smooth operation minimizes vibration and improves comfort during extended use
- Consistent Results - Uniform diamond distribution ensures even grinding across the entire surface
- Cost Savings - Durable construction means fewer replacements and lower project costs
- Enhanced Preparation - Creates the ideal surface profile for subsequent treatments, coatings, or polishing
- Professional Finish - Achieves commercial-grade results even in challenging applications

FAQ
How to choose the right bond types on cup wheel
THe cup wheels are mainly used to do prep or resurfacing job on concrete floors, however, the hardness of concrete varies. In order to complet the job with high effiency, it is essential to choose the right bond types. Here is the chart of how to define the concrete hardness.

Key Inspection Steps
There are 2 key inspections steps on concrete grinding wheels before delivery: the balance test, and bore hole test. If the cup wheels are not balanced well, it will jump during operation; The bore size will be smaller after painting, if not do the bore size test, it will be difficult to fit the cup wheel to angle grinder.
