Why Brazed Diamond?
| Feature | Benefit |
|---|---|
| Brazed bond | Diamond grains are chemically bonded to the steel core – much stronger than electroplated bonds |
| Single‑layer exposed diamonds | Maximum grain exposure for aggressive, fast cutting |
| 80 grit (coarse) | Rapid material removal – ideal for shaping and rough grinding |
| High grain retention | Diamonds stay in place longer, extending disc life |
| No loading | Open structure prevents clogging when grinding soft materials like glass or ceramic |
Key Benefits
1. Aggressive Material Removal
The coarse 80 grit brazed diamond layer cuts fast, making quick work of stone edges, ceramic tile shaping, and glass smoothing.
2. Long Service Life
Unlike electroplated discs where diamonds can pull out, the brazed bond holds each grain securely. This significantly extends working life.
3. Cooler Grinding
Brazed diamond tools generate less heat than resin or vitrified bonds, reducing the risk of thermal cracking on heat‑sensitive materials like glass.
4. Versatile
One disc handles multiple materials – stone, ceramic, glass, and even concrete or carbide.
5. Single‑Side Design
The single‑side brazing allows the disc to be used flat against the workpiece, ideal for edge grinding and surface smoothing.
Recommended Operating Conditions
| Parameter | Recommendation |
|---|---|
| Tool Compatibility | Angle grinder with 16mm arbor |
| Speed | 6,000 – 10,000 RPM (typical for 100mm disc) |
| Pressure | Moderate to light – let the diamond do the work |
| Cooling | Dry grinding is acceptable; water cooling extends disc life |
| Application | Edge grinding, surface smoothing, beveling, shaping |
Typical User Applications
Stone fabricators – Shaping granite or marble countertop edges
Tile installers – Trimming and shaping ceramic or porcelain tiles
Glass workshops – Smoothing cut glass edges
Concrete finishing – Grinding concrete surfaces or removing coatings
DIY and home renovation – General masonry and stone work
How to Use
Mount the disc on an angle grinder with a 16mm arbor
Wear appropriate safety gear (eye protection, gloves, dust mask)
Start the grinder and allow it to reach full speed
Apply light to moderate pressure – let the diamond cut
Move the disc across the workpiece in smooth, even passes
Tips for Maximum Disc Life
Avoid excessive pressure – this causes unnecessary wear
For glass and ceramic, use light pressure and intermittent contact to prevent heat buildup
For stone, consistent moderate pressure works best
Store discs flat in a dry location
