Sintered Diamond Grooving / Slotting Grinding Head (Metal Bond – with Grooved Design)
| Parameter | Value |
|---|---|
| Product Type | Sintered diamond grinding head / Mounted Point |
| Abrasive Type | Sintered diamond (metal bond – diamond throughout) |
| Special Design | Grooved / slotted working surface |
| Application | Milling, slotting, grooving, channel grinding |
| Target Materials | Glass, ceramics, stone, hard composites, engineered stone |
This sintered diamond grooving / slotting grinding head is specifically designed for milling slots, grooves, and channels in glass, ceramics, and other hard, brittle materials.
The sintered metal bond provides:
Diamond grit distributed throughout the working layer – long life
Self-sharpening action – consistent performance
Excellent wear resistance – ideal for abrasive materials
Good heat dissipation – cool grinding
The grooved / slotted design on the working surface offers:
Enhanced chip clearance – debris falls away
Cooler operation – reduced heat buildup
Faster cutting – interrupted cutting action
No loading – prevents clogging
Typical applications include:
✅ Milling slots and grooves in glass sheets
✅ Channel grinding in ceramic components
✅ Grooving in stone and engineered stone
✅ Slotting in hard composites
✅ Keyway and channel grinding in hard materials
| Feature | Benefit |
|---|---|
| Sintered diamond | Long life – diamond throughout the working layer |
| Grooved / slotted design | Chip clearance, cooling, no loading |
| Self-sharpening | Consistent cutting performance |
| Versatile | Works on glass, ceramics, stone, composites |

| Material | Suitability |
|---|---|
| Glass | ⭐⭐⭐⭐⭐ Excellent |
| Ceramics | ⭐⭐⭐⭐⭐ Excellent |
| Stone (granite, marble) | ⭐⭐⭐⭐⭐ Excellent |
| Hard composites | ⭐⭐⭐⭐ Good |
| Engineered stone | ⭐⭐⭐⭐⭐ Excellent |
| Step | Action |
|---|---|
| 1 | Mount the grinding head securely |
| 2 | Set speed: 8,000 – 15,000 RPM (material dependent) |
| 3 | Position the grooved surface against the workpiece |
| 4 | Apply light to moderate pressure – let diamond work |
| 5 | Use coolant for extended grinding (water or oil) |
| 6 | Dress when needed – refresh the surface with dressing stick |
| Parameter | Recommendation |
|---|---|
| Speed | 8,000 – 15,000 RPM |
| Feed rate | Slow to moderate |
| Coolant | Recommended (water or oil) |
| Dressing | As needed (with dressing stick) |
| Problem | Likely Cause | Solution |
|---|---|---|
| Slow cutting | Tool glazed or worn | Dress or replace tool |
| Excessive heat | No coolant or too much pressure | Add coolant; reduce pressure |
| Poor groove finish | Wrong grit or dull tool | Use finer grit; dress tool |
| Tool wears quickly | Too much pressure | Reduce pressure |
| Loading | Grooves clogged | Use coolant; clean with brush |
