| Parameter | Value |
|---|---|
| Outer Diameter (OD) | 125 mm |
| Body Material | Aluminum + Bakelite (hybrid) |
| Abrasive Type | Resin bond diamond |
| Rim Design | Serrated / segmented (slotted / toothed edge) |
| Application | Sharpening, edge profiling, grinding |
| Target Materials | Carbide tools, HSS, hard metals, ceramics, glass, stone |
This 125mm resin bond diamond grinding wheel features a unique aluminum and bakelite hybrid body with a serrated / segmented rim – specifically designed for sharpening, edge profiling, and aggressive grinding of hard materials.
The serrated rim design provides:
Enhanced chip clearance – material debris falls away
Cooler grinding – reduces heat buildup
Faster cutting action – interrupted cutting surface
Reduced loading – prevents clogging
The aluminum + bakelite body offers:
Lightweight construction – easy handling
Good vibration damping – smoother operation
Excellent strength and durability
Corrosion resistance
Typical applications include:
✅ Sharpening carbide tipped saw blades
✅ Edge profiling and grinding
✅ Tool sharpening and reconditioning
✅ Grinding ceramics, glass, and stone
✅ Surface preparation and finishing
| Feature | Benefit |
|---|---|
| Serrated / segmented rim | Chip clearance, cool grinding, fast cutting |
| Aluminum + bakelite body | Lightweight, strong, vibration damping |
| Resin bond diamond | Sharp, self-sharpening, good finish |
| 125mm diameter | Fits standard angle grinders and tool grinders |
| Versatile | Works on carbide, HSS, ceramics, glass, stone |
| Bond Type | Characteristics | Best For |
|---|---|---|
| Resin bond | Sharp, cool cutting, self-sharpening, good finish | Sharpening, finishing, general grinding |
| Metal bond | Long life, runs hotter | Production grinding |
| Ceramic bond | Hard, good form-holding | Precision grinding |
