Description
Technical Parameters
Angle Grinder Discs for Porcelain – Engineered for sintered stone. Smooth, chip‑free cuts, one blade for porcelain, ceramic, and natural stone.
This 4.5″, 5″, 7″ (115–180mm) angle grinder disc is designed specifically for sintered porcelain, compatible with most angle grinders and tile saws. Optimized for porcelain tiles - covering glazed, full‑body, polished, and large‑format porcelain - while also handling ceramic tiles, marble, and granite.
The industry truth about porcelain: It looks like stone, but it cuts like glass.
Modern porcelain has a Mohs hardness of 7-8, higher than granite (typically 6-7). It's fired above 1200°C from kaolin, quartz sand, and feldspar, with water absorption below 0.5% - high density, high hardness, but brittle. Industry consensus: blade wear on porcelain is 2-3x faster than on ceramic, and chipping rates are significantly higher.
The problem with standard blades is simple: they're not sharp enough. Segmented edges concentrate stress at the slots, and brittle porcelain fails at those points.
Our solution works on multiple fronts - continuous rim eliminates stress points, high‑exposure diamonds cut sharp from the first pass, and a soft bond self‑sharpens on hard particles. We offer both sintered (longer life) and brazed (sharper) processes, plus continuous rim (smoothest) and turbo (faster chip evacuation) rim designs to match your specific job requirements.
The root cause of chipping: standard blades have slots between segments. When cutting porcelain, those slots create stress concentration points. The brittle material fails along the slots. A continuous rim has no slots - stress is distributed evenly, and chipping drops significantly.
Our solutions cover both angles:
Continuous rim design - the entire rim is smooth, with no slots. Stress is distributed evenly across the cut. Virtually no chipping. Ideal for sink cutouts, trim cuts, and 45° mitre corners.
High‑exposure brazed diamond - diamonds are welded on the surface, not buried. Sharp from the first cut. Independent testing shows 60‑70% less chipping compared to standard sintered blades on glazed and full‑body porcelain.
Key technique: wet cutting + light pressure. Professional literature clearly states that letting the blade do the work and not forcing it is the fundamental principle of chip‑free cutting. Mark the cut line on the tile's back side before cutting, use water cooling to reduce heat and flush debris - a clean blade is a sharp blade. Wet cutting reduces chipping by an additional 10‑15%.
This is a common question from B2B buyers. Quick comparison:
| Feature | Continuous Rim | Turbo |
|---|---|---|
| Edge smoothness | Excellent | Good |
| Chipping rate | Very low | Low |
| Cutting speed | Medium | Faster |
| Chip evacuation | Fair | Good |
| Best for | Sink cutouts, mitre corners, visible edges | Floor tiles, thick tiles, fast cuts |
Quick guide:
Continuous rim - sink cutouts, trim cuts, 45° mitre corners. Edges come out machine‑smooth.
Turbo - large floor tile cuts, thick tiles (12mm+), fast material removal. Priority on speed.
The academic distinction is clear: continuous rim removes material by friction - minimal chipping. Segmented (including turbo) removes material by impact - faster but leaves fine tooth marks. Turbo sits in between - better edge than segmented, faster than continuous.

This is a core purchasing decision in the tile cutting industry. The market distinction between the two processes is very clear:
| Feature | Sintered | Brazed (optional on this product) |
|---|---|---|
| Diamond distribution | Throughout entire segment | Single layer on surface |
| Initial sharpness | Needs break‑in | Sharp from first cut |
| Cutting speed | Medium | Fast |
| Tool life | Long | Shorter |
| Self‑sharpening | Yes - new diamonds expose as metal wears | No - wears flat and stops |
| Best for | Continuous saw cutting, high volume | Angle grinder precision cuts, notches, curves |
How sintered works: diamond grit is mixed into metal powder and pressed. As the metal wears, new diamonds are exposed - the tool keeps cutting. Long life, dressable, ideal for table saws and continuous cuts.
How brazed works: diamonds are fused onto the surface in a single layer. Extremely aggressive from the first cut. But once the surface layer is gone, the blade stops cutting - shorter life than sintered. Test data shows vacuum brazed technology increases particle retention by 40% and cutting speed by 35% compared to traditional sintering. For angle grinder precision cuts, notches, and curves, brazed is the better choice.
We offer both. Here's our recommendation:
Table saw / bridge saw for large slabs → sintered
Angle grinder for sink cutouts, trim, mosaics → brazed
Application: Specialize in porcelain cutting. The good choice for DIY users!
The advantages are:
● Fast cutting
● No chipping
●Long lifespan
● High efficiency with low replacement frequency, save labor cost
