Do You Use a Hammer Drill for Tile?

No. Switch the hammer function off before the bit ever touches the glaze. That single setting is the difference between a clean hole and a spider-web crack radiating out from where you started drilling. We’ve been called out more than once to fix a bathroom accessory install gone wrong because someone left the hammer action engaged on their drill, and the tile paid for it.

Why Hammer Mode Cracks Tile

A hammer drill pulses forward as it spins, thousands of tiny impacts per minute meant to chew through concrete and brick. Tile is brittle and thin by comparison. It has none of masonry’s give. Those pulses transfer straight into the glazed surface, and a crack forms before you’ve even broken through to the substrate behind it.

Porcelain takes this worse than ceramic. It’s denser and harder, so it resists the hammering longer, then fails suddenly instead of chipping gradually the way softer ceramic sometimes does. Either way, once that crack starts, it doesn’t stay contained to your pilot hole. It runs.

What Setting Should You Actually Use

A hammer drill body is fine to hold. Plenty of us use the same drill for tile work that we use on concrete anchors an hour later. What changes is the mode dial: flip it to drill-only, no hammer, no impact. Most hammer drills have this switch built in, usually marked with a small hammer icon versus a plain drill-bit icon.

Speed matters as much as mode. Low RPM, steady pressure, let the bit do the cutting instead of forcing it. Push too hard on a diamond or carbide bit and you generate heat faster than the tile can dissipate it, which is its own path to a crack even with the hammer function off.

Can You Drill Into Tile With a Regular Drill Bit?

Depends what “regular” means here. A cordless drill on standard rotary mode, no hammer action, works fine for tile. Regular twist bits, the kind meant for wood or soft metal, do not.

Standard twist bits are built to cut and shear material away. Tile doesn’t cut. It has to be ground down, which is a completely different mechanism, and a twist bit’s edges dull against glazed porcelain almost immediately. You’ll get a burn mark, a lot of heat, and a bit that’s ruined for anything else, with no hole to show for it.

The drill itself: any standard rotary drill works, corded or cordless, hammer-capable or not, as long as hammer mode stays off. Bit choice is where tile actually needs something purpose-built.

Can You Use a Masonry Bit on Tile?

For ceramic, in a pinch, yes. Masonry bits have a carbide tip ground for hard materials, and that tip will scratch through a ceramic glaze if you’re patient and keep the speed low. We’ve done it on job sites more than once when a diamond bit wasn’t in the truck.

Porcelain is a different story. It’s harder than the carbide tip on most masonry bits, and you’ll wear the bit down faster than you cut through the tile. Trying to force it usually ends in a cracked tile and a dulled bit, the worst of both outcomes.

Masonry bits also assume hammer mode, since that’s what they’re designed for on brick and block. Running one on tile means deliberately working against how the bit itself was built. It’ll work on softer ceramic if you’re careful. It’s not the right tool for the job, and porcelain will humble you if you try.

The Right Bit for Each Tile Type

Diamond bits are the standard for porcelain, and the safest choice across every tile type. Its coating grinds rather than cuts, which matches how brittle, hard materials actually need to be worked. Buy a diamond hole saw for anything larger than a pilot hole, spade bits leave a mess on tile every time.

Carbide-tipped bits handle ceramic well and cost less than diamond. They won’t hold up on porcelain or natural stone the same way, so know which tile you’re working with before you buy. This matters most on a porcelain tile job, where the wrong bit choice is the difference between a clean anchor point and a callback.

Glass tile needs a diamond bit run even slower than ceramic or porcelain, since glass telegraphs cracks the fastest of anything on this list. Natural stone, granite, marble, quartz, wants a diamond bit too, and patience matters more than speed on all three.

Should You Drill Into the Tile or the Grout?

Grout looks like the easy way out. It’s softer, no glaze to fight, and a lot of homeowners assume that’s the safer target. It isn’t, not for anything load-bearing. Grout lines crumble and shift over time in a way the tile body never does, and a shelf bracket anchored in grout works loose within a year or two on most bathrooms we’ve serviced.

Drill into the tile field itself for anything carrying real weight: towel bars, grab bars, mirror brackets. Grout is fine for light, decorative hooks that don’t take much load, and even then a proper wall anchor sunk into the tile behind holds better long-term. The pilot-mark and cooling steps below apply either way, though grout drills faster and needs less patience on speed.

How to Drill Tile Without Cracking It

Mark the spot with painter’s tape first. Two strips crossed in an X, mark the centre point on the tape instead of directly on the glaze. The tape gives the bit something to grip on that first pass instead of skating across a slick glazed surface, which is where most cracked tiles actually start.

Start the hole at a shallow angle, almost flat against the tile, then walk the drill upright once you’ve scored a small divot. Going straight in from the first second is what causes bits to wander and chip the glaze at the edge of the hole.

Water keeps the bit cool. A spray bottle, a wet sponge dabbed on the spot every few seconds, even a small dam of tape and water around the hole on vertical surfaces: any of it works. Skip the water and heat builds fast enough to burn the diamond coating right off the bit.

Once through the glaze, ease off the pressure. The tile body underneath is usually softer than the glazed face, and pushing hard here is how a clean hole turns into a blown-out mess on the exit side, especially with wall tile that’s thin to begin with.

Common Mistakes We See on Site

Rushing is the big one. A proper hole through porcelain takes a couple of minutes at low speed, not thirty seconds of full throttle. Every rushed job we’ve been called to fix shows the same pattern: chipped edges radiating from a hole that was drilled too fast.

Skipping the pilot mark is close behind. Freehand starts on glazed tile almost always walk sideways before catching, and that skate mark doesn’t buff out. Forgetting water is third. Dry-drilling porcelain burns through diamond bits in a fraction of their normal life and raises crack risk with every extra second of heat.

Frequently Asked Questions

Will tile crack if you drill into it?

It can, and usually does if you use hammer mode, a dull bit, or too much pressure. Right bit, right speed, water for cooling: tile drills cleanly almost every time.

Will a normal drill bit go through tile?

Not without damage. A twist bit built for wood or metal burns and dulls against glazed tile long before it cuts through.

Does tile require a special drill bit?

Yes. Diamond or carbide-tipped, matched to whether you’re working ceramic, porcelain, glass, or stone.

What are common mistakes when drilling tiles?

Too much speed. No pilot mark on the glaze. Skipping water for cooling. Any one of the three raises crack risk on its own, and most botched holes we see combine at least two.

Can you drill a hole in tile without cracking it?

Reliably, yes, with the right prep. Painter’s tape for the mark, hammer mode off, diamond or carbide bit, low RPM, water to keep things cool.

What kind of drill do you use for tile?

Any standard drill works, corded or cordless, and a hammer drill body is fine as long as the hammer function stays switched off. Torque matters less than control here. A drill you can hold steady at low speed beats a more powerful one you can’t feather the trigger on.

What drill bit is best for tile?

Diamond for porcelain, glass, and natural stone. Carbide-tipped for ceramic, and cheaper if that’s what you’re working with. Either way, skip anything marketed as a general-purpose masonry bit unless it’s ceramic and you’re not fussed about wearing the bit out.

When to Call a Pro Instead

Expensive tile, a wall you can’t easily patch, or a spot near plumbing and blocking you can’t see behind: that’s where we tell homeowners to stop and call it in rather than risk a DIY crack. A cracked field tile on a $12-a-square-foot porcelain job costs more to source and replace than the hour it would have taken us to drill it right the first time. Towel bars, grab bars, shelf brackets on standard ceramic in a low-stakes spot: most homeowners handle those fine with the steps above. Anything bigger, or anything you’re not willing to gamble on near a fresh bathroom tile installation, is worth the call. Happy to walk through the specifics of your own room. Just ask us.
