Vacuum Brazed Diamond Porcelain Drill Bits – Professional Grade
Vacuum Brazed Diamond Porcelain Drill Bits – Professional Grade
-
The 45-Degree Start: Start drilling at a 45-degree angle to create a “cradle,” then slowly bring the drill to 90 degrees. This prevents the bit from wandering on slippery tiles.
-
No Downward Pressure: Let the diamonds do the work! Excessive pressure generates heat that can dull the vacuum brazed coating.
-
Circular Motion: Gently move the angle grinder in a slight circular motion while drilling to help clear dust and cool the bit.
-
Perfect for Dry Work: No need to mess with water pumps. Our vacuum brazed technology ensures high performance even in dry environments, saving you time on the job site.
Key Features
Our Vacuum Brazed Diamond Core Bits are engineered for professionals who demand precision. Unlike standard electroplated bits, the vacuum brazing process fuses diamond particles directly to the steel core, creating a much stronger bond.
Whether you are installing bathroom fixtures or kitchen countertops, these diamond porcelain drill bits provide:
-
Extreme Versatility: One bit for all hard masonry—porcelain, ceramic, marble, and granite.
-
High-Speed Efficiency: Optimized for high-RPM angle grinders, cutting through 10mm tile in seconds.
-
Durable Core: Reinforced 45# grit steel body ensures the bit remains stable under high temperatures.
