DAYDOOR Dry Diamond Drill Bits Set — 10-Piece Tile & Stone Drill Kit with Cooling Wax

DAYDOOR Dry Diamond Drill Bits Set: Precision for Tile, Glass, and Stone

When you tackle ceramic tile, porcelain, granite, or glass, you want a drill bit that stays true. DAYDOOR’s 10-piece diamond drill bit set combines a hardened steel core with diamond grit, delivering consistent starts and clean holes. The built-in cooling wax melts as you drill, helping manage heat and reducing wear. The kit ships with a mix of sizes (two of each: 6mm, 8mm, 10mm, 12mm) plus two pilot bits, giving you options from small pilot holes to larger openings for fixtures, outlets, or decorative features.

What’s included

• 9 diamond drill bit sizes plus 2 pilot bits (two 6mm, two 8mm, two 10mm, two 12mm) for flexible planning
• Centering pilot drill for accurate starts on glass and smooth tile surfaces
• High-carbon steel core with vacuum-brazed diamond grit for hardness and wear resistance
• Integrated cooling wax inside each tip; supports both dry fast cutting and wet drilling for longevity
• Suitable for ceramic tiles, ceramic floors, rock, porcelain, glass, marble, granite, stone, and jade (not for water, cement, steel, wood, or plastic)

Real-world use cases

• Kitchen renovations: drill precise holes for outlets, fixtures, and cable pass-throughs in tile or stone countertops
• Bathroom tiling: create clean holes for faucets, towel racks, and shower fittings without chipping
• Outdoor installations: mount glass panels, decorative stonework, or granite accents with confident starts
• Automotive and equipment maintenance: add pass-throughs or guide holes on hard surfaces with minimal wander

Performance and durability you may notice

The set’s materials are engineered for durability: vacuum-brazed diamond grit on steel stands up to repeated drilling, and the built-in cooling wax helps maintain tip integrity during longer tasks. While dry drilling yields speed, wet drilling can prolong tool life and protect surfaces from heat buildup.

Storage and care

All bits arrive in a sturdy box for organized storage and safe transport between jobs, reducing the chance of loss or misplacement on busy sites.

Important notes

Not suitable for drilling through water, cement, steel, wood, or plastic. Follow safety guidelines and use appropriate clamping and PPE.
