Drilling into tile is one of the most nerve-racking DIY jobs. One wrong move, a wandering bit, or too much pressure and you are staring at a cracked tile that needs replacing. The challenge is real—tile is brittle, glass-hard, and unforgiving. The right bit changes everything, turning a risky operation into a clean, predictable process.
I’m Rikta — the co-founder and writer behind FitlyFast. I’ve spent years analyzing market data and breaking down the real-world specs of drilling hardware to help homeowners and pros choose tools that actually deliver on their promises.
After comparing over a dozen products and combing through user experiences, this guide cuts through the noise to reveal the best bits for drilling tile so you can drill with confidence every single time.
How To Choose The Best Bits For Drilling Tile
Picking the wrong drill bit for tile is the fastest route to cracked material and wasted money. The key is matching the bit’s material, tip design, and cooling method to your specific tile hardness and project scale. Ceramic tile, porcelain, natural stone, and glass all demand different cutting geometries.
Carbide-Tipped vs Diamond-Grit: The Material Split
Carbide-tipped bits use a brazed carbide insert that bites into softer tile like ceramic and natural stone. They are effective at low speeds and work well with hammer drills on masonry. Diamond-grit bits, both sintered and vacuum-brazed, grind through porcelain and glass with a sanding action. Diamond bits handle harder materials but require patience and consistent cooling to avoid burning out the diamonds.
Cooling Strategy: Wax, Water, and Heat Management
Heat is the enemy of any tile bit. Friction dulls carbide edges and sheds diamond grit prematurely. Bits with built-in cooling wax inside the barrel offer longer dry-drilling windows. For wet drilling, a spray bottle or damp sponge keeps the cutting surface below 140°F, which preserves the bond holding the diamond particles. Never use hammer mode on tile—vibration causes cracking regardless of the bit.
Shank Compatibility and Drill Fit
Standard round shanks fit most handheld drills, but hex shanks provide better grip and reduce spin-out in higher-torque situations. Larger core bits (1-inch plus) often use a 5/8-11 thread designed for angle grinders or dedicated core drill rigs. For common household holes—mirror mounts, shower grab bars—a 1/4-inch hex shank bit is the sweet spot.

In‑Depth Reviews
1. BGTEC Diamond Core 10pcs Set (1/4-Inch)
This 10-piece kit delivers vacuum-brazed diamond technology that holds up across porcelain, granite, and glass. Each bit has an 8mm diamond segment and a built-in wax core for cooling during dry drilling, plus a side hole for clearing stone chips. Users report drilling five holes in hard porcelain with a single bit when using a light water spray—a strong return on a multi-bit investment.
The round shank fits standard drill chucks, and the kit provides a range of sizes suitable for most household anchor holes and small hardware installations. The diamond grit is aggressive enough to start without a pilot bit, though using a center punch or a scrap wood template reduces the risk of walking on glazed surfaces.
For anyone tiling a shower wall or installing glass shelving in a ceramic surround, this set offers the best balance between performance and value. The multiple bits mean you have spares for future projects, and the vacuum-brazed bond outlasts electroplated alternatives on repeated use.
Why it’s great
- Ten bits cover common sizes from one kit
- Vacuum-brazed diamond holds up on hard porcelain
- Integrated wax core reduces need for constant water
Good to know
- Bits can wander if not held perfectly straight
- Smaller bits may wear after 5-6 uses on dense stone
2. DEWALT DW5572 Diamond Tip (1/4-Inch)
The DW5572 uses a diamond-welded tip and a reverse spiral that pulls water into the cutting zone, cooling the interface and flushing debris upward. This design allows for longer drilling runs without overheating. One verified buyer drilled twelve holes through half-inch porcelain tile with a single bit, still functional afterward.
Its core ejection slot makes plug removal straightforward—no prying or chipping around the hole edge. The single-bit format is ideal when you need one reliable, repeat-use tool for a specific hole size, such as 1/4-inch for toggle bolts or shower hardware anchors.
Pairing this bit with a wooden template pre-drilled with the same 1/4-inch hole eliminates the starting wander that frustrates many first-time tile drillers. It is a go-to for pros who prioritize hole quality and bit longevity over lowest upfront cost.
Why it’s great
- Welded diamond tip lasts multiple holes in hard porcelain
- Reverse spiral delivers continuous water cooling
- Core ejection slot speeds up plug removal
Good to know
- Single bit format means limited size range
- Not recommended for hammer-mode drilling
3. Bosch NS2000 4pc Natural Stone Tile Set
The NS2000 uses a Multigrind carbide head with multiple cutting edges designed specifically for natural stone, slate, and granite. Bosch claims 20 percent faster drilling than standard glass-and-tile bits, and user feedback confirms sharp, clean holes in quartz and marble with minimal chipping. The 3-flat shank on 3/8-inch bits and above prevents chuck slippage under load.
This set includes four sizes—1/8, 3/16, 1/4, and 5/16 inch—making it versatile for anchor holes and small fixture mounts. It is also compatible with hammer drills for masonry applications, but keep hammer mode off when drilling tile. The carbide tip geometry centers the bit on contact, reducing the need for a pilot punch.
Note that Bosch explicitly advises against using these bits on porcelain tile; the carbide wears too quickly on that dense, sintered material. For ceramic and natural stone, however, this is a precise, durable option that does not overheat as easily as diamond tips in softer stone.
Why it’s great
- Multigrind head delivers faster cuts in natural stone
- Three-flat shank eliminates drill chuck slippage
- Four sizes cover small-to-mid anchor holes
Good to know
- Not suitable for porcelain tile drilling
- Carbide wears faster than diamond on hard materials
4. WildBossy Concrete Carbide 10pc Set
This 10-piece WildBossy set covers sizes from 5/32-inch up to 1/2-inch, with tungsten steel carbide tips and a 135-degree split point that bites aggressively into tile, concrete, brick, and cement. The hex shank design locks securely into the drill chuck, reducing spin-out and bit wandering during start-up on smooth glazed tile.
Users highlight its effectiveness for installing wall anchors, bathroom fixtures, and shelving hardware. The split-point tip centers quickly on ceramic tile, and the range of sizes eliminates the need to buy multiple individual bits for different anchor diameters. For glass and tile, a low speed and steady pressure are recommended—no hammer mode.
While the carbide tips are durable, they are not designed for repeated use on porcelain. For a job site with mixed materials—tile, brick, concrete, and plastic—this set handles most tasks without switching to a dedicated diamond bit. Keep a spray bottle handy for the tile work.
Why it’s great
- Hex shank prevents slipping during start-up
- Ten sizes from 5/32 to 1/2 inch cover all anchors
- Split-point tip reduces walking on glazed tile
Good to know
- Carbide tips wear faster on dense porcelain
- Slightly undersized compared to stated diameters
5. BGTEC Masonry 10pc Tungsten Carbide Set
The BGTEC masonry set uses YG6X cemented tungsten carbide, a grade known for high hardness and abrasion resistance. Bits come in 5mm, 6mm, 8mm, 10mm, and 12mm sizes—all with quick-fit hex shanks for fast chuck changes. The precision crosshead carbide tip reduces slippage on smooth tile surfaces.
Verified buyers report drilling 24 clean holes in porcelain for mirror and hook installations when using intermittent water cooling. The key technique: start at a 45-degree angle to score the glaze, then ease into perpendicular drilling. The set includes two 5mm, four 6mm, two 8mm, and one each of 10mm and 12mm bits.
This set bridges the gap between light ceramic work and occasional porcelain drilling. The YG6X carbide holds an edge longer than standard carbide, but on large projects with dense tile, water cooling is essential. Without it, bits overheat and lose cutting efficiency.
Why it’s great
- YG6X tungsten carbide offers high abrasion resistance
- Quick-fit hex shank allows rapid bit swapping
- Multiple sizes accommodate various anchor needs
Good to know
- Requires water cooling for hard tile
- Not designed for glass or diamond-drilling applications
6. DKIBBITH 2pc Dry Diamond Core Set (1/4-Inch)
These DKIBBITH diamond core bits use a 5/8-11 thread designed for angle grinders, making them a solid choice for users who already own a grinder rather than a standard drill. Each bit includes dense cooling wax inside the barrel to manage heat during dry operation, with a maximum working depth of 1.37 inches.
The two-pack provides a spare bit for larger or multiple-hole jobs. Users report clean holes in porcelain tile when starting at a 45-degree angle and gradually tilting upright. The diamond height of 10mm gives enough cutting surface for most single-tile passes without excessive wear.
If you work primarily with an angle grinder and need a compact core bit for tile, this set offers a cost-effective alternative to larger, more expensive core systems. The wax core helps in dry drilling, but adding water extends cutting life significantly.
Why it’s great
- 5/8-11 thread fits standard angle grinders
- Dense cooling wax extends dry-drilling time
- Two bits included for long or backup use
Good to know
- Not suitable for standard handheld drill chucks
- Shallow working depth limits thick material drilling
7. SALI 5-Inch Diamond Core Bit
This is a large-format diamond core bit built for big openings in concrete, brick, and masonry walls. With a 5-inch diameter and a drilling depth of 10 inches, it is appropriate for installing range hood vents, air conditioner pipes, and bathroom exhaust ducts. The laser-welded turbo segments cut aggressively without a pilot bit.
The kit includes two adapters—a 3/8-inch hex shank adapter and a 5/8-11 male to SDS-plus adapter—making it compatible with standard drills, SDS-plus rotary hammers, and angle grinders. Users report cutting eight-inch deep holes in reinforced concrete in about thirty minutes, with the bit still sharp afterward.
This is a specialized tool for heavy structural work, not for small tile repairs. If your project requires a large hole through tile-covered concrete or brick, the SALI core bit delivers clean results and saves significant rental costs compared to hiring a core drill rig.
Why it’s great
- Laser-welded diamond segments cut concrete and brick cleanly
- Two adapters included for drill and SDS compatibility
- 10-inch drilling depth handles thick foundation walls
Good to know
- Overkill for standard tile-only projects
- Requires steady drill orientation to avoid binding
