Take the guesswork out of tile and stone installations with the Diablo 3-1/2 in. Carbide Tipped Tile and Stone Drill Bit Set. This 5-piece collection is purpose-built for clean, accurate holes through ceramic tile, porcelain tile, and natural stone, delivering durable performance when you need it most on kitchens, bathrooms, and shower enclosures.
-
Carbide-tipped precision— engineered for hard, abrasive materials, these tips stay sharper longer and resist wear when drilling through tile and stone, reducing the need for frequent bit changes.
-
Five-piece assortment— a handy range of diameters in a single carded set, so you have the right size for mounting hardware, fixtures, and pass-throughs without running to the store mid-project.
-
1/4" hex shank— a secure, slip-free fit for most drills and impact drivers, enabling steady, confident drilling without bit wobble.
-
3-1/2" overall length— compact enough for controlled starts yet long enough to reach through tile thickness and thin-set, making deeper work straightforward in tight spaces.
-
Convenient packaging— carded packaging keeps the set organized for job sites and retail display, so you can grab the right bit quickly when you need it.
Use cases and scenarios
- Installing faucet and faucet-rough-in holes in ceramic or porcelain tile without cracking surrounding material.
- Creating clean, true-through holes for anchoring brackets, towel bars, and fixtures in stone or tile surfaces.
- Patio or backsplash projects where precise hole diameters are essential for fit and finish.
Why this set stands apart
- Carbide tips deliver longer bit life on tough tile and stone compared with standard high-speed steel bits, reducing downtime and replacement costs.
- The hex shank design translates to reliable bite and minimal slipping, even when drilling into dense or thicker materials.
- Thanks to the 3-1/2" length, you can work with thicker tile or deeper substrates without changing bits mid-project.
Tips for best results
- Drill at a steady, moderate speed and use a light touch to prevent chipping. Let the bit do the work—don’t push aggressively.
- Keep the work area cool with a splash of water or cooling spray to prolong bit life and reduce heat buildup.
- Start with a light pilot hole or center-mark the drill point to minimize wandering on smooth tile surfaces.
Ideal for DIY enthusiasts upgrading their bathroom or kitchen projects, as well as professional tile installers who value durable, reliable performance from a ready-to-use set. The Diablo name assures a practical, task-focused tool designed to get clean holes through tile and stone with confidence.
