Drill and grind through porcelain, marble, and glass dry, with no water hose to drag into a finished room and no risk of surface spider cracks.
The TitanEdge 2-in-1 brazed-diamond bit handles both drilling and grinding in a single bit. It works on porcelain, tile, marble, granite, glass, jade, and agate, delivering clean holes without the need for water and without marring the surface.
With one bit you can bore a hole for a shower valve and then ream it to size for the trim plate—no tool swap required. The bit’s design provides dry cutting with minimal heat buildup, so you won’t burn out the edge mid-job.
Diamond grit is brazed to the steel core using a high-temperature alloy, keeping diamonds exposed for sharp, continuous cutting. This construction stays cool enough to cut dry and sheds heat as it wears, unlike electroplated alternatives that can dull quickly.
Whether you’re drilling through glaze or widening openings, the bit’s spear-like edge is designed to bite on contact, reducing wandering and glaze chipping. It’s built to work with standard drill equipment and doesn’t require water cooling for common hole sizes.
The shank is a 1/4 inch (6.25 mm) hex, so it locks directly into any standard drill driver or impact driver chuck—no adapters or chuck keys needed.
Options include a 3-piece set (6, 8, 10 mm) or a 4-piece set (6, 8, 10, 12 mm). Finished in silver or gold with a titanium coating, the TitanEdge bit is designed for dry cutting through porcelain, ceramic tile, marble, granite, glass, jade, and agate.
| TitanEdge Brazed Diamond Bit | Spear-Tip Glass & Tile Bits | Water-Cooled Core Bits |
|---|---|---|
| Drills AND grinds with the same bit — no tool swap mid-job | ❌ | ❌ |
| Runs dry through porcelain — no water rig, no drip pan | ❌ | ❌ |
| 1/4" hex shank fits every driver — drill OR impact | ❌ | ❌ |
Drilling and grinding in one tool keeps you moving—no swapping bits or tools mid-task. The dry-cut capability avoids water rigs and mess, allowing clean holes in finished spaces. The 1/4" hex shank fits standard drill drivers and impact drivers, so you can use the tool you already own without adapters.
How to use
- Snap the TitanEdge hex shank into your drill driver—no adapter or chuck key needed.
- Place the bit flat against the tile, begin at low RPM to engage the glaze, then increase speed. Use rotation only, not hammer mode.
- Apply gentle pressure to pierce the back of the tile, then remove debris and proceed to the next hole.

Real users report cracking tiles with other brands; TitanEdge lets you finish a shower wall with multiple holes without cracking a single tile, using a single bit from start to finish.
