EXTRACUT Vacuum Brazed Diamond Core Drill Bit is engineered for fast, clean hole drilling in hard and brittle materials such as porcelain tile, ceramic, granite, marble, and engineered stone. Utilizing advanced vacuum brazing technology, diamond grit is permanently bonded to the steel body under high temperature and controlled atmosphere, delivering aggressive cutting action, minimal chipping, and a long, predictable tool life.
Key Features
- Vacuum Brazed Bond — High-temperature brazing creates a strong metallurgical adhesion between diamond particles and the steel shank, enabling fast penetration and reduced risk of segment loss under load.
- Multi-Material Versatility — Cuts efficiently through porcelain, ceramic tile, granite, marble, glass, and composite stone without switching tools.
- Clean Edge Quality — Sharp diamond exposure minimizes breakout and micro-cracking on delicate surfaces, leaving a professional finish suitable for visible installations.
- Dry & Wet Use — Performs reliably in dry job-site conditions; water cooling can be added to extend bit life and control dust when equipment permits.
Applications
Ideal for plumbing and electrical through-holes in porcelain and ceramic wall and floor tiles, countertop faucet and sink cutouts in granite and engineered stone, ventilation and conduit openings in hard-burnt brick and marble cladding, and decorative inlay work where edge quality is critical.
