Which blade cuts laminate?
A triple-chip or negative-hook blade for worktops, and a reverse-tooth jigsaw blade for laminate flooring cut face up.
Laminate is a thin, hard, brittle melamine surface over a soft core, so it chips at the moment a tooth exits the decorative face. Every workable method comes down to controlling which face the teeth exit through and how big a bite each tooth takes. On a worktop, the trade practice is to cut it face down with a circular saw and a fine blade, running against a clamped guide, with masking tape over the line. On flooring, a reverse-tooth jigsaw blade lets you cut with the finished face visible, which is what you want when you are scribing to a doorframe. A blunt blade chips laminate badly regardless of type, and the ragged edge is usually hidden by trim only in the simplest cuts.
The options, ranked
| Option | Good at | Bad at |
|---|---|---|
| Triple-chip grind blade | Alternating flat and chamfered teeth take small bites, which is what brittle melamine and laminate need. | Slower feed rate, and it dulls fast if it meets the substrate's glue line repeatedly. |
| Negative hook blade | The teeth scrape rather than pull, so the saw does not snatch the sheet or chip the surface. | Requires more feed pressure and is not ideal for general timber. |
| Reverse-tooth jigsaw blade | Cuts on the down-stroke, so the finished face can be uppermost — the answer for laminate flooring. | Rougher on the underside and more prone to wander. |
| Laminate cutter (guillotine) | Silent, dust-free and instant for cross-cuts on flooring planks. | Straight cross-cuts only; no rips, notches or curves. |
Technique that changes the outcome
- Tape over the cut line and mark on the tape
- Score the line with a knife before sawing on a visible edge
- Clamp a straightedge guide; a wandering cut chips as it corrects
- Support the sheet fully so it cannot flex and pinch the blade
- Feed slowly and evenly rather than forcing the saw
What goes wrong
- A coarse general-purpose blade in laminate
- Cutting a worktop face up with a circular saw
- Rushing the feed, which chips the leading edge of the cut

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. |
| Tile | A continuous-rim diamond blade with water — and cut wet, because dry cutting tile produces respirable silica dust. |
| 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. |
| 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. |
