Which blade cuts tile?
A continuous-rim diamond blade with water — and cut wet, because dry cutting tile produces respirable silica dust.
Diamond blades do not cut; they grind, with the diamonds embedded in a metal bond that is designed to wear away and continually expose fresh ones. That means heat is the enemy — an overheated blade glazes, the bond hardens and the diamonds stop being released — which is why wet cutting matters as much for the blade as for the operator. The operator side is more important still: tile, and especially porcelain, contains crystalline silica, and dry cutting releases it as a fine respirable dust that causes silicosis with repeated exposure. Water suppression or on-tool extraction with an appropriate mask is the standard control, and it is exactly the sort of exposure that accumulates unnoticed over years of occasional jobs.
The options, ranked
| Option | Good at | Bad at |
|---|---|---|
| Continuous rim diamond blade | The smoothest edge on ceramic and porcelain, with the least chipping. | Slowest, and it must be cooled with water or the rim glazes over. |
| Turbo rim | Serrated rim clears debris and cuts faster while still leaving a reasonable edge. | More chipping than a continuous rim on glazed faces. |
| Segmented rim | Fast and cool-running, and the right choice for masonry. | Chips tile badly; it is the wrong blade for a visible edge. |
| Manual score-and-snap cutter | No dust, no noise, no power, and a clean edge on straight cuts in ceramic. | Straight cuts only, and it struggles with thick porcelain. |
Technique that changes the outcome
- Cut wet on a tile saw wherever possible, keeping water on the blade
- Mark on masking tape to reduce chipping at the entry
- Feed slowly and let the blade grind; forcing it glazes the rim
- Cut with the glazed face up on a wet saw so any chipping happens on the back
- If a blade stops cutting, dress it on an abrasive block to expose fresh diamonds
What goes wrong
- Dry cutting tile without extraction and respiratory protection
- A segmented masonry blade on a visible tile edge
- Running a diamond blade dry when it is specified for wet use

Other blade questions
| For | Use |
|---|---|
| Metal | A bi-metal or carbide-tooth blade with at least three teeth in the cut — that tooth-count rule matters more than the machine. |
| Wood | 24 teeth for ripping and framing, 40 for general work, 60-80 for a clean crosscut finish. |
| Plywood without tearout | A sharp 60-80 tooth blade, a scoring pass, tape on the line, and the good face oriented for the tool you are using. |
| Brick | A segmented-rim diamond blade, cut wet or with on-tool extraction — brick and mortar dust is a serious silica hazard. |
| Laminate | A triple-chip or negative-hook blade for worktops, and a reverse-tooth jigsaw blade for laminate flooring cut face up. |
| Acrylic | A triple-chip negative-hook blade on a table saw, or score-and-snap for thin sheet — and keep the feed steady so it does not melt. |
| Glass | None — a tungsten carbide scoring wheel, one firm pass with oil, then snap it. And toughened glass cannot be cut at all. |
| Plasterboard | A utility knife for straight cuts and a jab saw or multi-tool for cutouts — a circular saw is the wrong tool entirely. |
| Plastic pipe | A fine 24 TPI hacksaw or a proper pipe cutter — and deburr the inside afterwards, which is the step people skip. |
