Jigsaw blade choice for tiles is different from every other material you’ll cut. Tiles are hard, brittle, and prone to chipping if you use the wrong blade or technique. A jigsaw isn’t the fastest tile-cutting method — a tile cutter or angle grinder will be quicker for straight cuts — but if you need a curved cut or a precise hole around a toilet flange or drain, a jigsaw is the most controllable tool you have.
The key difference is that tile blades use grit particles embedded in the blade edge rather than sharp teeth. Diamond grit is fast and cuts cold. Carbide grit is slower but more precise. Both work differently from metal or wood blades, and speed, cooling, and technique are critical to avoiding splintering.
Quick Blade Recommendations for Tiles
| Tile Type | Best Blade | Grit Type | Speed | Why It Works |
|---|---|---|---|---|
| Ceramic wall tile (6–10mm) | Bosch T150RD | Diamond | 30–40% | Diamond grit, compact design, cuts cleanly with water cooling |
| Porcelain (glazed) | DeWalt DT2168 | Diamond | 30–40% | Diamond bond, tough enough for hard porcelain, prevents chipping |
| Natural stone (marble, slate) | Bosch T150RD | Diamond | 30–40% | Diamond cuts stone without fracture; water cooling essential |
| Glass tile | Bosch T150RD | Diamond | 20–30% | Slowest speed; water cooling prevents heat cracking |
| Unglazed ceramic | Bosch T150RD | Diamond | 40–50% | Softer than glazed ceramic; standard diamond blade works well |
Diamond Grit vs Carbide Grit — Which One for Your Job?
Tile blades don’t have teeth. Instead, they have tiny particles of diamond or carbide pressed into the blade edge. These particles grind away the tile surface rather than cutting cleanly through it.
Diamond Grit Blades
Diamond is harder than carbide and cuts faster. Bosch T150RD and DeWalt DT2168 are both diamond grit blades.
- Speed: Fast cutting (30–40% speed setting on your jigsaw)
- Heat generation: Moderate — diamond dissipates heat well
- Finish: Good on ceramic and unglazed tile; can cause glazed tiles to chip slightly
- Cost: £15–22 per blade
- Best for: Ceramic tiles, natural stone, quick cuts where some chipping is acceptable
Diamond grit is the standard choice for most tile work because it’s a good balance of speed and finish. If you’re cutting 20–30 tiles and want to finish in an hour, diamond is what you use.
Carbide Grit Blades
Carbide is slightly softer than diamond but cuts more precisely with less chipping. Carbide blades are rare for jigsaws (they’re more common on table-mounted tile saws), but they exist for precision work.
- Speed: Slower (20–30% speed setting)
- Heat generation: Higher — carbide builds heat faster, needs more cooling
- Finish: Excellent; minimal chipping even on glazed porcelain
- Cost: £18–28 per blade (more expensive than diamond)
- Best for: High-end tile, glazed porcelain, expensive natural stone where every chip matters
If you’re cutting a single expensive tile or need a perfect edge on a visible installation, carbide is worth the cost. But for most jobs, diamond is faster and adequate.
Ceramic vs Porcelain Tiles — Different Hardness, Different Approach
Ceramic Tiles (Standard Wall Tile)
Standard ceramic wall tiles (6–10mm thick) are what you find in most bathrooms and kitchens. They’re soft enough to cut with a diamond blade at moderate speed without problems.
- Hardness: Medium (softer than porcelain)
- Blade: Bosch T150RD, 30–40% speed
- Water cooling: Recommended but not essential if you’re only cutting a few tiles
- Chipping risk: Low — ceramic tiles are forgiving
Ceramic cracks if you push too hard, but it’s nowhere near as brittle as glazed porcelain or glass. Feed the jigsaw slowly and let the grit particles do the work. The blade will make a grinding noise — that’s normal. It’s not cutting with teeth; it’s grinding through the material.
Porcelain Tiles (Hard, Glazed)
Porcelain is fired at much higher temperatures and is much harder than ceramic. Many porcelain tiles are also glazed (shiny coating) which is even more prone to chipping. This is the most difficult tile to cut with a jigsaw because the glaze is brittle.
- Hardness: Very hard (2–3x harder than ceramic)
- Blade: DeWalt DT2168 or Bosch T150RD (diamond only; carbide can work but slower)
- Water cooling: Essential — porcelain heats up quickly and heat causes chipping and glaze damage
- Speed: 30–40% maximum; slower than ceramic
- Chipping risk: High — especially on the underside (exit) of the cut
Porcelain is worth cutting slowly because damage is expensive to fix. The glaze coating is only 0.1mm thick; once it’s chipped, you can’t touch it up. Use water cooling on every porcelain cut.
Natural Stone Tiles — Marble, Slate, Granite
Natural stone is unpredictable. It looks solid but has internal planes of weakness that can fracture if you use the wrong speed or technique. Unlike ceramic, you can’t just push forward — stone needs respect.
Marble & Limestone
Marble is relatively soft for stone. Diamond blade, 30–40% speed, water cooling every 30 seconds.
- Problem: Marble has natural veining and grain; cuts parallel to the grain are easy, but across-grain cuts can fracture
- Solution: Mark out your cut line carefully and feed very slowly (2–3 cm per 5 seconds). Let the blade grind, don’t force it
- Cooling: Spray water constantly — marble fractures if it overheats
Slate
Slate splits along planes. Cuts parallel to the planes are easy; cuts across them risk splintering.
- Blade: Diamond, Bosch T150RD
- Speed: 25–35% (slower than marble because slate is harder)
- Cooling: Heavy water cooling — slate is very heat-sensitive
- Technique: Feed slowly and consistently. Don’t stop mid-cut; it tends to freeze and be hard to restart without chipping
Granite
Granite is the hardest natural stone and the worst candidate for jigsaw cutting. A diamond blade will cut it, but slowly and with a high risk of splintering.
- If you must cut granite with a jigsaw: Diamond blade, 20–30% speed, constant heavy water cooling, feed very slowly (1 cm per 5 seconds)
- Better option: Use an angle grinder with a diamond cup wheel for curved cuts, or a wet saw for straight cuts. A jigsaw is the wrong tool for granite.
Water Cooling Technique — Essential for Hard Tiles
Water cooling is not optional for porcelain, stone, or glass. The grit particles generate friction heat that can cause two problems:
- Heat causes the tile surface to expand and contract, creating stress cracks or chipping
- Heat builds up in the blade itself, which can dull the grit or cause the blade to expand and bind
Water Cooling Method
Use a spray bottle filled with water. Every 15–20 seconds, spray the blade and cut line liberally. You’re looking for a wet, muddy grinding surface — that’s the sign cooling is working.
Why spray, not immersion? A spray bottle gives you control. If you dip the jigsaw in water, the baseplate gets wet, which causes rust. Spray the cut area only.
How much water? Enough to keep the cut area wet and create a muddy slurry. Don’t use so much that water pools — it’ll interfere with your line of sight and create an electrical hazard.
Frequency: Every 15–20 seconds for porcelain and glass. Every 30 seconds for ceramic and stone (less critical but still recommended).
Speed Settings — The Critical Variable
Speed on a tile blade directly affects finish and chip risk. Too fast and you generate heat and chipping. Too slow and the blade will bind.
- Glass tile: 20–30% (slowest; glass is extremely heat-sensitive)
- Glazed porcelain: 30–40% (hard and prone to chipping)
- Unglazed ceramic: 40–50% (softer; can go faster)
- Natural stone: 25–35% (varies by hardness; marble is softer than slate)
If the blade is making a squealing noise or the cut is slow and rough, you’re going too slow. Increase speed by 10%. If the tile is chipping or cracking, you’re going too fast. Decrease speed by 10% and cool more frequently.
Scoring Technique — An Alternative Method for Straight Cuts
For straight cuts in thin ceramic (6–8mm), some tilers use a scoring technique instead of cutting all the way through:
- Set the blade to 20–30% speed
- Feed the jigsaw lightly, making a shallow score groove (1–2mm deep) along your cut line on the top surface
- Stop the saw and let the tile cool for 30 seconds
- Place a block under the score line and tap the overhang gently with a hammer — it will snap cleanly along the score
This method reduces heat generation and produces a cleaner edge because you’re not grinding all the way through. It works well for 6–8mm ceramic wall tile but not for porcelain or thicker tiles.
Jigsaw vs Tile Cutter vs Angle Grinder — Know Your Tool Limits
A jigsaw can cut tiles, but it’s not always the best tool. Understand the alternatives:
Wet Tile Saw (Table-Mounted)
Best for: Straight cuts in any tile. Speed: Fastest. Finish: Best in class.
A professional wet saw is the gold standard for tile cutting. It has a built-in water circulation system and a powerful motor. But it costs £200–600 and is for contractors who cut tiles daily.
For one-off cuts: A jigsaw is cheaper and more portable.
Manual Tile Cutter (Snap-Type)
Best for: Straight cuts in ceramic only. Speed: Very fast (snap in 5 seconds). Cost: £15–40. Finish: Clean.
A manual tile cutter works by scoring and snapping. It’s perfect for ceramic wall tiles but cannot cut porcelain (too hard to snap). It also cannot make curved cuts.
Jigsaw advantage: Works on any tile and cuts curves.
Angle Grinder with Diamond Cup Wheel
Best for: Curved cuts in hard tiles, speed when you have lots to cut. Speed: Fast (but sparks and noise). Finish: Good but rougher than a jigsaw.
An angle grinder can cut any tile, including granite, and produces curved cuts. But it creates dust, noise, and sparks. It’s also less controllable for precision cuts.
Jigsaw advantage: Quieter, more control, no dust clouds.
When to Use Each Tool
- Jigsaw: Curved cuts, precision holes, one or two tiles, quiet indoor work
- Manual tile cutter: Straight cuts in ceramic, fastest if you have 10+ straight cuts
- Wet tile saw: Professional jobs with 50+ cuts, any tile type, best finish
- Angle grinder: Hard stone, speed when you don’t mind dust, curved cuts on tough materials
Cutting Holes in Tiles — Toilet Flanges & Drains
Cutting a hole for a toilet flange or shower drain is the toughest jigsaw tile job. You’re cutting in the middle of the tile with no straight edges to guide the blade.
Hole-Cutting Method
- Mark the hole: Use a compass or hole saw template to mark the exact centre and circumference on the tile surface
- Drill a pilot hole: At 12 o’clock (top) of your marked circle, drill a small pilot hole (3–5mm) to give the blade a starting point
- Lower the blade: Angle the baseplate and lower the spinning blade gently into the pilot hole. Don’t plunge — use the baseplate as a guide
- Follow the line: Once in, rotate the jigsaw around the circle, following your marked line. Keep the baseplate flat
- Cool frequently: Spray water every 5–10 seconds. The heat buildup in a hole cut is intense
- Final arc: As you near the end and return to your starting pilot hole, support the cut piece so it doesn’t drop and crack
Hole cuts take 3–5 minutes in ceramic, 5–10 minutes in porcelain, and are extremely difficult in stone. If you have multiple holes to cut, an angle grinder with a diamond hole saw or core drill is faster.
Blade Compatibility — T-Shank & Grit Types
Tile blades come in T-shank (modern universal) and U-shank (older). Check your jigsaw manual:
- T-Shank: Bayonet mount, one-click fit. Bosch and DeWalt tile blades are all T-shank and interchangeable
- U-Shank: Screw clamp (older design). Ask your supplier for U-shank tile blade alternatives if your saw uses this
The Bosch T150RD and DeWalt DT2168 are both T-shank and will fit any modern jigsaw.
Safety — Dust, Noise & Eye Protection
Cutting tiles creates fine dust that can contain silica. When you breathe silica dust over time, it can cause serious lung disease (silicosis). Protect yourself:
- Dust mask: Wear an FFP2 or FFP3 mask rated for silica dust (not just a paper dust mask). N95 masks are not adequate for tile dust
- Eye protection: Wear safety glasses. Tile fragments can spin off at the blade entry point
- Hearing protection: Tile cutting is loud. Wear ear plugs if you’re cutting for more than 15 minutes
- Water containment: When using water cooling, water will pool and splash. Cover the work area with a tarp to contain it
- Electrical safety: Keep water away from the saw’s power cord and plug. Use a residual current device (RCD/GFCI) outlet if you’re using water near electrics
Buying Guide — Blade Sources
Tile blades are more expensive than wood or metal blades (£15–22 per blade), but they last longer because you’re only cutting a few tiles before you move on. A single diamond tile blade will cut 10–20 tiles before dulling, which is much longer than a wood blade.
Common Mistakes — And How to Avoid Them
Using a Wood or Metal Blade on Tile
This is the biggest mistake. A wood blade will shatter immediately on tile. A metal blade will slip and won’t cut at all. Use a grit blade (diamond or carbide) — it’s the only design that works on tile.
Going Too Fast
High speed on tile creates heat and chipping. If your cut is chipping, slow down. Most people cut tile too fast because they’re impatient — resist the urge.
Not Cooling Hard Tiles
Porcelain, glass, and stone need water cooling. Skip this and you’ll get heat cracking and chipping every time. Keep a spray bottle handy.
Ignoring Dust
Silica dust is invisible and dangerous. Use a proper FFP2/FFP3 mask, not a paper dust mask. One day of tile cutting without a mask might not hurt you, but over years it accumulates.

Frequently Asked Questions
Can I use a jigsaw to cut porcelain tiles?
Yes, but with caution. Glazed porcelain is very hard and prone to chipping. Use a diamond blade (Bosch T150RD or DeWalt DT2168), set speed to 30–40%, and use water cooling every 15–20 seconds. A single chip in the glaze is permanent and cannot be touched up. If you have many porcelain tiles to cut, use a wet tile saw instead.
What’s the difference between diamond and carbide grit blades?
Diamond: Harder, faster, less precise. Best for ceramic and stone. Carbide: Slightly softer, slower, more precise, lower chipping risk. Best for expensive glazed porcelain where every chip matters. For most jobs, diamond is adequate and cheaper.
Do I need to cool ceramic tiles when cutting?
Not essential if you’re only cutting a few ceramic tiles. Ceramic is forgiving and doesn’t overheat as quickly as porcelain or glass. But if you’re cutting 10+ tiles, water cooling every 30 seconds will speed up the job because the blade stays sharper longer.
Why is my tile blade squealing and not cutting?
You’re going too slow. Tile blades need speed to cut efficiently. Increase your speed setting from 20% to 30% or 40% and try again. Squealing means the grit particles aren’t engaging properly with the surface.
Can I cut glass tiles with a jigsaw?
Yes, but glass is the most heat-sensitive material. Use a diamond blade at 20–30% speed (slowest setting) and cool very frequently (every 10–15 seconds). The glaze on glass tiles is extremely prone to heat cracking. If you have many glass tiles to cut, use a wet tile saw instead.
What’s the best way to cut a hole for a toilet flange?
Drill a pilot hole at the top of your marked circle, lower the spinning blade into it, and rotate around the circle. Cool every 5–10 seconds. Support the cut-out piece at the end so it doesn’t crack from its own weight. Hole cuts are slow (3–10 minutes) and difficult — if you have multiple holes, rent or use an angle grinder with a diamond hole saw instead.
Is a manual tile cutter faster than a jigsaw?
For straight cuts in ceramic, yes — a snap cutter is 10x faster (5 seconds vs 1–2 minutes). But a snap cutter cannot cut porcelain or curved lines. Use a tile cutter for bulk straight ceramic cuts and a jigsaw for curves, porcelain, or precision holes.
Do I need a dust mask when cutting tiles with water cooling?
Yes. Water cooling reduces airborne dust but doesn’t eliminate it. Wear an FFP2 or FFP3 mask rated for silica to protect your lungs. Silica dust is invisible and cumulative — one cut won’t hurt you, but years of exposure can cause serious lung disease.
