Applications
Vacuum brazed diamond core bits are made for drilling clean, accurately sized holes in hard, brittle materials where ordinary twist or masonry bits tend to chip, crack or burn the surface.
- Ceramic and porcelain wall and floor tiles, including glazed and large-format tiles
- Glass panels, glass tiles and glass blocks
- Natural stone such as marble, granite and slate
- Engineered stone, quartz and other sintered surfacing materials
- Terrazzo and cement-based tiles
- Installation work such as holes for faucets, shower fittings, wall anchors and decorative fixings
FAQ
What materials can these diamond core bits drill?
They are intended for glass, tile, ceramic, stone and similar fragile materials. They are not designed for cutting or drilling iron, steel or other metals.
What does "vacuum brazed" mean?
Vacuum brazing bonds the diamond grit directly onto the steel body of the bit. The diamond layer forms the working edge that grinds through the material, which is why these bits suit hard, brittle surfaces rather than general-purpose drilling.
Why buy a multi-size kit instead of a single bit?
A kit covers several drilling diameters in one set, so you can match the hole size to the fitting, pipe or anchor you are installing without ordering individual bits for each job.
How do I choose the right size for my job?
Match the bit diameter to the item that will pass through or sit in the hole — for example a faucet shank, a pipe or a wall anchor. Because the kit contains multiple sizes, you can select the closest match before starting to drill.
Can these bits be used on metal or wood?
No. The diamond abrasive edge is specified for glass, tile, ceramic and stone. Using them on iron, steel or other metals is outside their intended application.
