## Long description

Diamond core drill bit GRAPHITE 72x8x75 mm model 57H877 is a cylindrical cutting tool intended for creating precise holes in hard building materials. The bit has an outer diameter of 72 mm, a cutting width of 8 mm and a total length of 75 mm. It is suitable for wet and dry drilling and can be used with handheld drills and drill presses when fitted with a compatible arbor. The design and diamond cutting segment make it effective for perforating concrete, masonry, ceramic tiles and natural stone while producing clean, well-defined cores.
Advantages
The diamond cutting rim provides efficient material removal and longer life compared with standard carbide bits when working on abrasive substrates. Its dimensions (72×8×75 mm) deliver consistent cylindrical cores with minimal chipping around the hole edge. The bit supports both wet and dry drilling modes, enabling flexible use on site or in controlled workshop conditions. Compatibility with common arbors allows use on handheld and stationary drilling machines for plumbing, electrical and installation tasks.
Suitable for
 Drilling holes in concrete for anchor and pipe installations
 Creating openings in masonry and block walls
 Cutting circular holes in ceramic and porcelain tiles
 Forming through-holes in natural stone for fixtures and fittings
Key specifications

 Total length: 75 mm
 Cutting material: diamond segment
 Suitable drilling modes: wet and dry
 Compatible with: handheld drills and drill presses when used with appropriate arbor
 Primary materials: concrete, masonry, ceramic tiles, natural stone
How to use
Secure the diamond core drill bit to a compatible arbor and mount it in the chosen drilling machine. For best results on reinforced concrete and abrasive materials, use a drill with sufficient power and, if possible, a drill press to maintain perpendicular alignment. When dry drilling, apply moderate feed pressure and allow the bit to cool periodically; when wet drilling, ensure continuous water supply to the cutting edge to reduce dust and extend segment life. Maintain steady, controlled rotation speed appropriate for the material and drill size, and remove cores carefully after completion.
Usage recommendations
Use personal protective equipment (safety glasses, dust mask or respirator for dry drilling, hearing protection and gloves). Choose wet drilling where practical to improve cutting performance and reduce dust. Verify arbor compatibility before operation and inspect the segment condition regularly; replace the bit if significant wear or damage is visible. For through-holes in tiles and stone, start at low speed and light pressure to prevent cracking, then increase feed once the segment has established the cut.
