2024’s Best Drill Bits for Tile, Tested and Reviewed
Hello, my friend, hello again; today we come together to talk about 2024’s Best Drill Bits for Tile, Tested and Reviewed and hope the blog can help you.
We tested drill bits specifically designed to make holes in tile. Find out how they fared on various tile types, including ceramic, marble, granite, and more.
Drilling holes in tile—to install towel rods in a bathroom renovation, say—can be tricky. There’s always a risk the tile will crack, especially if you use the wrong drill bit. What’s more, attempting to drill tile with a standard steel bit designed for use on wood can cause the bit to overheat, bend, or even break in half. Of course, with the right bit, drilling tile can be nearly as straightforward as drilling wood—and since most tile drill bits and drill-bit sets are fortunately affordable, it makes sense to have the right tool.
However, tile is made from various materials, so it’s crucial to select the right bit for the specific material. To help DIYers and pros alike get great results, we tested some of the best-rated designated tile bits, creating holes in ceramic, porcelain, marble, glass, and stone tiles. As we expected, some performed better on one type of tile than another. Our favorite was the Owl Tools 10-Piece Masonry Drill Bit Set for its impressive durability and wide range of sizes to meet most tasks. Ahead, learn about drilling in different types of tile and find out how the following bits earned a spot on our lineup of the best drill bits for tile.

How We Tested the Best Drill Bits for Tile
Over the years, we’ve had plenty of practice drilling tile, so our experience combined with in-depth product research was instrumental in selecting the drill bits for testing. We considered the brand to an extent—DeWalt and Bosch are both top manufacturers of construction tools—but didn’t automatically eliminate drill bits from smaller or niche manufacturers if they featured carbide or diamond tips and were rated well by consumers.
Our actual testing process was straightforward. All of the drill bits were tested using a standard cordless drill. We used masking tape on the tops of some tiles, which can help keep bits from wandering and reduce the risk of the tile chipping during the drilling process. It’s not always necessary, so we didn’t tape all the tiles—for example, the surface of a travertine tile is soft and porous, and most bits will not wander when drilling through travertine. As the manufacturer suggested—or if a bit was struggling to drill through—we added a few drops of water while drilling to help keep the bit from getting too hot and breaking.
We tested the bits by drilling multiple holes, but we only tried them on tile types they were designed for. In short, we did not test a bit made for drilling ceramic or glass tiles on porcelain tiles, which are much harder. Our goal was to determine how well the bits stood up to their intended drilling purposes.
We scored each bit (or bit set) using a rubric throughout the hands-on testing process. The better a drill bit performed, the higher the score. We looked for durability and relatively smooth-edged holes—it’s not unusual to have some slightly ragged edges, however. We did not judge the bits on how long it took to drill through a tile because different types of tile require longer drilling times, and it’s counterproductive to exert strong pressure while drilling as it can cause the bits to break. After drilling an initial 10 holes with each bit, we inspected them for dulling and wear before drilling more holes.
We finished by adding up the scores and using them to determine the best categories for each set of drill bits.

When folks have a variety of different tile materials to tackle, it can be difficult to pick the best drill-bit set. In our tests, this 10-piece set of masonry drill bits from Owl Tools demonstrated a high level of durability while the spear tips proved to reduce wandering (sliding across the surface of glazed tile before creating a hole). The shanks are made from steel and the bits boast carbide tips for added hardness.
We tested the Owl Tools bits on several types of tile, including marble, travertine stone, shale, glazed ceramic, and glass tiles. We used masking tape on some of the tiles to further reduce the risk of wandering and prevent surface chipping, but we also drilled holes without the benefit of tape, and the Owl Tools bits excelled in both cases. We drilled all the test holes without adding drops of water because the bits were drilling so well dry, we didn’t feel water was needed.
After drilling 10 holes, we checked the bits for wear. The carbide-tipped spears were still sharp, and none of the bits had broken. After 30 more holes in various types of tile, we noticed the bits (we tested one of each size) were starting to drill slower. Upon inspection, we found the spear tips were beginning to wear down—but we still consider that superior performance for drilling about 40 holes in hard tiles.
Another advantage to the Owl Tools set is the number of different-size bits. The set includes 10 bits that range in diameter from ⅛ inch to ½ inch in both 4-inch and 6-inch lengths, making this tile-drilling bit set suitable for drilling a range of hole sizes in several common types of tile.

Best Bang for the Buck
Hillman Tapper Carbide Tipped Drill Bit
Photo: Amazon
Our Ratings: Effectiveness 5/5; Performance 4.5/5; Durability 4.5/5; Value 5/5
Product Specs
- Tip material: Carbide
- Number of bits: 1
- Sizes: 3/16 inch (3½ inches long)
What We Liked
- Carbide tip makes quick work of drilling through ceramic tile and softer stone tiles, such as travertine and marble
- Buying bits in individual sizes is often more economical than buying a set of bits that won’t get used
- The flutes (spiral grooves) on the bit’s shank work to bring powdered tile material up and out of the hole for cleaner drilling
What We Didn’t Like
- Unsuitable for porcelain, and while it will drill through glass, other bits are better for glass tile
When a project requires only a few holes to be drilled in tile, consider buying a single bit rather than a whole set, such as this Hillman Tapper drill bit in a 3/16-inch diameter and 3½-inch length. (We chose that size to test because 3/16-inch is a fairly standard hole size for installing towel rods and toilet-paper-holder anchors). We drilled holes in marble, travertine, slate, glass, and ceramic tiles with this carbide-tipped spiral bit. We did use masking tape for most of the holes because the bit had a tendency to wander without it. The bit drilled clean holes in ceramic and stone tiles but seemed to struggle on the glass tile, so we added a few drops of water to the hole to help cool the bit and reduce friction (not cooling a hot bit is a primary cause of bit breakage).
After drilling more than 45 holes, the Hillman bit started to slow down, and we could see that the tip was softening and wearing down some. However, we felt its performance and durability were still good under pressure, and the bit never broke. A single-size bit won’t be suitable for all tile-drilling purposes, but it’s more economical to buy just one if only drilling a few holes of the same sizes.

Best Glass Tile Set
Bosch GT2000 4-Piece Glass and Tile Bit Set

Our Ratings: Effectiveness 4/5; Performance 4/5; Durability 5/5; Value 4.5/5
Product Specs
- Tip material: Carbide
- Number of bits: 4
- Sizes: ⅛ inch, 3/16 inch, ¼ inch, 5/16 inch (2 to 2¼ inches long)
What We Liked
- Carbide tips make these bits suitable for drilling through glass tiles
- Spear tips help start a hole and gradually enlarge it to reduce cracking
- Bits are durable and hold up to making dozens of holes
- Suitable for drilling through other types of tile, including travertine and marble
What We Didn’t Like
- Without masking tape on the top of the glass, the bits tend to wander
Drilling in glass tiles is more straightforward than it might seem—a good carbide-tipped blade is essential, as is using a slow drill speed. The four-piece bit set from Bosch excelled in our glass-drilling tests.
The set comes with bits ranging from ⅛ inch to ⅝ inch in diameter and from 2 inches to 2¼ inches long. Each bit features a spear tip with a sharp point the manufacturer claims will keep the bit from wandering. Unfortunately, we found each one of the bits tended to wander on the glass tiles unless we used masking tape—an easy fix that didn’t detract from the bits’ performance and durability. Wandering is common when drilling through tiles, so everyone should be prepared to use tape.
After 10 holes, we inspected the bits. The largest one showed a slight amount of wear on the edges of the spear blades, while the others looked nearly new. They all went on to drill 30 more holes apiece, but toward the end, they made slower progress, and we had to exert more pressure on the drill. Fortunately, we didn’t have any cracked glass tiles after all the drilling. That’s largely due to the sharpness and durability of the bits, but we also give a little credit to an old computer mouse pad that we placed beneath some of the tiles as we drilled, which absorbed some of the vibrations and may have helped prevent cracking.
While our main objective in testing these bits was to determine their performance on glass, we also tried them afterward on a marble tile and a travertine tile. At this point, the bits were slightly worn down but still drilled through both materials cleanly, albeit slowly.

Best Professional
DeWalt Rapid Load Carbide Masonry Drill Bit Set
Photo: Ace Hardware
Our Ratings: Effectiveness 5/5; Performance 5/5; Durability 5/5; Value 4/5
Product Specs
- Tip material: Carbide
- Number of bits: 7
- Sizes: 3/16 inch, ¼ inch, 5/16 inch, ⅜ inch, ½ inch (lengths from 3 to 6 inches)
What We Like
- Strong, durable bits easily drill through a variety of tile types
- They didn’t show wear or dulling even after making dozens of holes
- Set contains bits of several diameters and lengths for versatile hole drilling
What We Didn’t Like
- We found the bits wandered a bit on glass tiles if masking tape wasn’t used
- These bits are not designed to drill holes in porcelain tile
We’re well aware of the superior quality of many DeWalt power tools and accessories, so it was no surprise that the company’s seven-piece set of masonry drill bits excelled at drilling through tile. The set features bits ranging in diameter from 3/16 inch to ½ inch with lengths ranging from 3 inches to 6 inches. Three of the bits are ¼ inch, which is a commonly used size.
We used the DeWalt bits to drill through travertine, slate, marble, ceramic, and glass tiles. The bits have carbide spiral tips, and we tested them with and without masking tape. They wandered less than we expected, even without tape, but we would suggest taping highly glazed ceramic and glass tiles to be on the safe side.
These proved to be very durable heavy-duty bits: After drilling 10 holes with each, we saw virtually no softening of the blades or dulling. As we drilled an additional 30 holes per bit, we still didn’t notice much slowing down. The deep flutes in the shank quickly removed the powdered tile material as we drilled, and the holes were clean and uniform.
With the largest ½-inch bit, we did crack two glass tiles, but we feel that was primarily due to our wrists and arm muscles becoming fatigued and not holding the drill as stable as we should have. A few days after the original test, we tried again and drilled through glass tiles with no cracking. We feel these DeWalt bits fit the bill for professionals needing durable bits on the job.

Best Metric Set
Qwork Multi-Material 8-Piece Drill Bit Set
Photo: Amazon
Our Ratings: Effectiveness 4/5; Performance 4/5; Durability 3/5; Value 4/5
Product Specs
- Tip material: Carbide
- Number of bits: 8
- Sizes: 3, 4, 5, 6, 8, 10, 14, and 16 millimeters
Pros
- Set contains 8 different-size bits for versatility
- Spear tips offered precise drilling without wandering
- Metric sizes make this set suitable for installing or assembling fixtures for metric-size fasteners
Cons
- Bits cannot be used on porcelain
- This is a light-duty drill-bit set only and will not stand up to heavy use
With a growing number of kitchen and bathroom fixtures now supplied in metric sizes, it may be necessary to have an accurate metric drill bit for tile. Imperial (United States) equivalents are close but not always close enough. In the past, we’ve had to guess which Imperial bit or anchor is most comparable to the metric one called for, so we were excited to test these carbide-tipped metric drill bits.
After drilling 10 starter holes, we examined the spearheads of the bits. The two smallest bits showed substantial dulling and wear on the blades, so we set those aside and continued with the other five. None of the other bits made it past 25 additional holes, so we can’t rate the Qwork bits as the most durable of the ones we tested. Perhaps the steel wasn’t quite as high in quality—but we still deem these bits to be a decent option for jobs that require metric bits and fasteners, since those are typically small projects, such as installing a towel bar or a ceramic soap dish. And interestingly, these bits didn’t wander much, not even on un-taped glass, so they earned a point in that department. Consider these as light-duty tile-drilling bits for metric usage.
