The Diablo DMANSP1060 1/2 in. Hard Tile & Stone Carbide Tipped Drill Bit is a carbide tipped drill bit built for drilling fast, accurate holes in hard tile, stone, and glass. This is a glass and tile drill bit designed for hard surface hole drilling in materials that usually chip, skate, or burn up ordinary bits. Model Number: DMANSP1060. If you are installing hardware, anchors, fixtures, or fasteners through porcelain, ceramic tile, marble, granite, or other stone surfaces, this is the kind of bit you reach for.

What matters here is not just the diameter. It is how the bit starts and how long it stays useful. Diablo builds this bit with an asymmetric carbide tip design to increase drilling speed and extend tip life versus standard glass and tile drill bits. The multi-ground carbide Grip Point tip is there for a reason: it gives the bit a more stable starting point so you can place holes with better accuracy instead of watching the bit slide across a finished tile face.

The carbide itself is also a big part of the story. Diablo states that its carbide and hardening process are designed to withstand impact for greater durability and longer life than standard tile and stone hammer drill bits. On the job, that means better productivity when you have a run of holes to make in tough material and do not want to swap bits every few minutes. Diablo rates this line for up to 10X longer life versus standard glass and tile drill bits, which is exactly the kind of thing pros care about when drilling expensive finish surfaces.

The 1/2 inch diameter makes this bit a practical choice when you need larger anchor holes or clearance holes in brittle materials. At 3-1/2 inches overall length, it stays compact enough for good control in a drill driver while still giving you reach for common installation work. The hex shank is another real-world upgrade. It helps eliminate spinning in the chuck, improves stability, and gives better power transfer from the drill to the bit. That matters most when you are leaning into a hard tile surface and need the bit to stay planted.

This Diablo drill bit is built to run in cordless and corded drill drivers and is also noted as ideal for hammer and rotary drills. That gives it broad tool compatibility for crews already working across different drill platforms. If your day-to-day work moves from bathroom tile to stone backsplashes to outdoor masonry-adjacent finishes, having one hard tile and stone bit that fits standard hex-chuck setups keeps things simpler.

It is a strong fit for tile installers, remodelers, plumbers, electricians, maintenance crews, and general contractors who routinely need clean penetrations through finished surfaces. Serious DIY users will also appreciate it when the job calls for drilling through porcelain or glass without wrecking the workpiece. Bottom line: this is not a throwaway masonry bit pretending to work on tile. It is a purpose-built hard tile and stone drill bit for clean starts, better control, and longer service life in some of the toughest finish materials you will drill.
