We’ve all been there—staring at a tile that needs a big hole cut into it, wondering how to pull this off without turning it into a pile of expensive shards. Here’s the thing: with the right technique, you can cut clean circles for pipes, drains, or fixtures like a pro. So, what’s the secret to keeping your tile intact? Well, it comes down to choosing the right tool and knowing a few tricks that make all the difference.

ToggleChoose Your Method by Hole Size and Tile Type
Before you grab any tool and start drilling into your tile, let’s figure out what’ll actually work for the job.
Here’s what I think: measure your hole first. For anything 4 1/2 inches or smaller, a diamond-tipped drill bit works great.
Going bigger? You’ll need a diamond hole saw with a core drill attachment.
Porcelain’s tougher, so diamond-studded tools are your best bet.
Water-fed saws keep things cool and dust-free.
Honestly, measuring techniques matter just as much as the tool itself.
Alternative tools like angle grinders work too, especially for irregular shapes.
What do you think makes sense for your project?
Mark the Perfect Circle With a Compass or Template
Grab your compass or template—this step makes or breaks your whole project.
We’ll mark that center point first, then carefully measure our radius to match the hole size. Here’s what I think: don’t rush this part.
Mark your center point with precision, measure the radius carefully, and resist the urge to rush through this critical step.
Lightly score the circle with a pencil so you’ve got a clear guide, even if it disrupts existing tile patterns. Use a straightedge to verify everything’s symmetrical—trust me, it matters.
Double-check those measurements before cutting. Following basic safety precautions now saves headaches later.
Can you imagine starting over because of sloppy marking? Not fun.
Cut Large Holes in Tile Using an Angle Grinder
Once you’ve got your circle marked, it’s time to fire up that angle grinder and get cutting. Here’s what I think works best: start with 45° plunge cuts along your marked line, accounting for tile thickness.
Then switch to 90° cutting angles as you work around the perimeter. So, keep steady pressure but don’t force it—you won’t believe this, but patience prevents cracks.
Carefully shave away material inside the circle, moving slowly. Well, finish by smoothing those edges with a grinding bit.
Can you imagine that perfect hole?
Drill Large Holes in Tile With a Diamond Hole Saw
When you need a perfectly round hole for pipes or fixtures, a diamond hole saw makes the job way easier than you’d think. Here’s what I think—it’s all about technique:
- Attach your diamond bit securely and mark the center point.
- Start at a 45° angle to prevent cracking, then shift to 90°.
- Keep your drill speed steady and controlled.
- Use water to cool the bit and cut down on dust.
- Apply gentle pressure in shallow passes.
Combine a Wet Saw and Grinder for Oversized Holes
For those massive holes that go beyond what a standard hole saw can handle, there’s a killer combo technique we’ve found works like a charm. Start with your wet saw to cut straight lines along your outline—think of it as sketching your opening.
When a standard hole saw won’t cut it, this killer combo technique lets you sketch out massive tile openings like a pro.
Then switch to an angle grinder with a diamond wheel to refine everything. Here’s what I think: cutting safety matters most, so support that tile properly and use water to cool your blade.
Tool maintenance tip? Keep those diamonds sharp. Work slowly, and you’ll nail it.
Can you imagine cracking after all that effort?
Smooth Rough Edges With a Diamond File After Cutting
After you’ve wrestled that big hole into your tile, you’re not quite done yet—those edges are probably rougher than sandpaper. Here’s what I think: edge polishing makes all the difference in tile finishing.
So, let’s smooth things out with a diamond file.
- Secure your tile firmly on a stable surface before starting.
- File using small, consistent strokes with moderate pressure.
- Apply a fine-grit diamond file for the best polishing results.
- Keep strokes along the edge to avoid uneven surfaces.
- Rinse the tile afterward to reveal that clean finish.
Can you imagine skipping this step? Don’t risk those jagged edges.
Avoid These 7 Mistakes That Crack Tiles During Cutting
Cracking a tile during cutting feels like watching all your hard work shatter in an instant—and trust me, we’ve all been there.
Here’s what I think: most breaks happen from pushing too hard or rushing the cut. Proper tool maintenance matters—dull blades chip tiles fast. Can you imagine that?
Correct measurement techniques prevent uneven pressure that causes cracks. We’ve learned to support tiles firmly, cut at steady speeds, and score carefully first.
You won’t believe this, but slowing down actually saves time by avoiding do-overs. So, sharp blades and patient hands keep your tiles intact every time.
Keep Blades Wet to Prevent Overheating and Dust
While cutting through tile, water becomes your blade’s best friend—and honestly, it’s a game-changer we can’t skip. Here’s what I think: proper blade maintenance starts with keeping that water supply flowing.
So, what does water actually do?
- Dissipates heat, preventing overheating that kills your blade
- Suppresses dust particles, protecting your lungs
- Reduces friction and wear on the diamond edge
- Prevents tiles from cracking due to thermal stress
- Maintains consistent cutting speed and efficiency
You won’t believe this, but a simple damp sponge works wonders.
Can you imagine cutting dry? Your blade won’t last long.
Safety Gear for Cutting Large Holes in Tile
Before you even pick up that grinder, let’s talk about protecting yourself—because honestly, cutting tile isn’t worth a trip to the emergency room. Here’s what I think: you need proper gear before making a single cut.
| Safety Item | Why You Need It |
|---|---|
| Eye protection (goggles or faceshield) | Stops flying debris from hitting your eyes |
| Safety gloves | Protects hands from sharp edges |
| Dust mask or respirator | Keeps tile dust out of your lungs |
| Hearing protection | Blocks damaging grinder noise |
| Closed-toe boots | Shields feet from dropped tools |
Practice on Scrap Tile Before Cutting Your Final Piece
If you’re anything like me, you’ll want to grab some scrap tile first—trust me on this one.
Here’s what I think: practicing prevents costly mistakes. So, work with tiles matching your project’s tile thickness.
- Use identical or similar tiles to simulate real cutting conditions
- Experiment with different punch tools and methods to find what works best
- Learn how much pressure and speed create clean, precise holes
- Understand your specific tile’s behavior before committing to the final piece
- Reduce cracking and chipping risks during actual installation
Can you imagine ruining expensive tile? Well, we can avoid that completely.
Frequently Asked Questions
How to Cut a Large Circle in Tile?
We’ll mark our circle, then use a diamond hole saw at 45° before going vertical—thrilling stuff! Remember tile sealing afterward and safety precautions like eye protection, because nothing says fun like tile shards everywhere.
What Can I Use to Cut a Hole in Tile?
We’d recommend using diamond-tipped hole saws or core bits for clean cuts, followed by proper tile sealing. An angle grinder with a diamond blade works too, though you’ll need careful grout removal around edges for best results.
How to Drill a Large Hole in Tiles?
We’ll use a diamond-tipped hole saw with steady, light pressure while applying water for cooling—essential safety precautions that prevent cracking. This tile maintenance technique requires marking your center point precisely and drilling at slow speeds for professional results.
How to Cut a Hole in Tile Already Installed?
We’ll carefully mark the hole location, then drill pilot holes around the perimeter using proper cutting tools. While prioritizing tile safety, we’ll use an angle grinder with a diamond blade to connect the holes, ensuring we support the tile firmly throughout.
