Drill & Grind Through Porcelain, Marble and Glass — No Water, No Cracks
Designed for DIY enthusiasts and tile professionals who break carbide bits on tough porcelain, the TitanEdge™ 2-in-1 brazed-diamond bit both drills and grinds tile, marble, granite, glass, jade, and agate — dry, fast, without causing spider cracks. One bit, one chuck, zero water hoses dragged into the bathroom.
End Bit Snaps and Tile Cracks
Porcelain acts like glass to standard drill bits. Carbide tips overheat and slide across the glaze. Spear-tip glass bits dull after a couple holes and start chipping edges. Water-cooled core bits do work — but who wants to drag a hose into a finished bathroom on a weekend? You need a bit that bites on contact, cuts dry, and keeps its cool past the third hole.
➤ Drill AND Grind With One Bit: Create a clean hole for your shower valve, then tilt to grind it larger for the trim plate — all without swapping bits. One bit does both tasks.
➤ Cuts Porcelain Dry — No Water, No Mess: The brazed diamond grit stays cool enough to cut without water, even on hard porcelain and stone. Drill straight through finished bathroom wall tiles — no drip trays, no spray bottles, no wet drywall.
➤ 1/4" Hex Shank Fits Any Driver: The 6.25mm hex shank fits snugly into any standard drill or impact driver chuck — no adapters or chuck keys needed. Take it out, snap it in, start drilling.
Brazed Diamond Grit — Why It Cuts Dry Without Burning Up
Most cheaper diamond bits rely on electroplated coatings — a single grit layer that flakes off as soon as it heats up. TitanEdge™ uses brazed diamond grit instead. The diamonds bond to the steel core with a high-temp alloy, allowing edges to stay exposed as they wear, and letting heat dissipate quickly enough for dry cutting.
That separates a bit that “lasted one bathroom and died” from one that drills clean holes through 30+ porcelain tiles before slowing. The grit works with your drill — no slipping, no glazed chips, no spider cracks.
Why Both Pros and Weekend DIYers Keep These in Their Drill Kits
From bathroom renovators to jewelers working with jade and agate, and tile pros who avoid dragging water rigs into finished rooms — everyone hits the same obstacle and reaches for this solution. "Cracked three tiles using my Dewalt bits until I tried these. Then drilled the rest of the shower wall with a single 8mm bit with zero cracks." — Mike R.
Finish What You Started — Without the Cracked-Tile Stress
✓ Cuts Porcelain, Marble, Granite and Glass Dry: No water rig, no drip pans, no mess on finished walls — just a perfect hole on the first try.
✓ Drill AND Grind Using One Bit: Drill your hole, then ream it to size without switching tools.
✓ Fits Any Standard Chuck: 1/4" hex fits drill drivers and impact drivers alike — including the one already in your hand.
3 Easy Steps From Box to Drilling
Step 1: Snap the TitanEdge™ hex shank into your drill driver — no adapters or chuck keys required.
Step 2: Place the bit flat against the tile, start on low speed to grip the glaze, then gradually increase. Use rotation only — no hammer mode.
Step 3: Ease off pressure as you break through the tile’s back. Pull out, blow off dust, move to the next hole.

Real Questions From Real Customers
Will it fit my drill?
Yes — the 1/4" (6.25mm) hex shaft fits into all standard drill and impact driver chucks on the market. No adapter or chuck key required.
Does it work on hard porcelain tile?
Absolutely. Brazed diamond grit cuts porcelain, marble, and granite cleanly. Begin with low RPM and steady pressure to bite the glaze without slipping, then increase speed. Avoid hammer mode.
Can I use hammer or impact mode?
Rotation only — no hammer. Hammer action breaks the brazed bond and ruins the bit quickly. Use standard drill mode or impact driver in screw-drive mode as intended. "Ruined my first bit running hammer by mistake. The second one drilled 14 holes and still cuts clean." — Dan T.
Do I need water?
No water is necessary for typical hole sizes in tile, marble, or glass — the brazed bond cools enough to cut dry. For longer grinding or thicker stone, a light spray of water between holes can prolong bit life.
How long does one bit last?
Used properly (rotation only, light pressure, no hammer mode), one bit can cover a typical bathroom project — 30+ holes in ceramic, 15–25 in dense porcelain. Keep dry when stored to protect the bond.
