## Long description

Diamond core drill bit INDIAN PROFESSIONAL Korona Diamentowa Hex 12 mm is a specialist 12 mm diameter bit designed for dry drilling in hard materials where diamond cutting is required. The bit has a hexagonal shank for secure engagement with chucks and drivers that accept hex bits, enabling stable rotation and reduced slippage during drilling. It is intended for creating precise small-diameter holes in construction and finishing applications.
Advantages
The diamond cutting edge provides efficient material removal when working with very hard surfaces, extending usable life compared with standard carbide bits in demanding applications. The hex shank offers reliable retention in quick-change chucks and impact drivers, improving torque transfer and reducing the risk of bit cam-out. The 12 mm diameter is suitable for installations that require accurate, repeatable holes without the need for cooling fluids, as the design supports dry drilling.
Suitable for
 Dry drilling small-diameter holes in ceramic tile and porcelain
 Creating precise openings in natural and engineered stone
 Drilling through thin concrete, masonry, and cement-based substrates
 Installation tasks for plumbing, electrical boxes, and fixtures requiring 12 mm holes
Key specifications
 Cutting material: diamond-segment edge for hard material cutting
 Drill diameter: 12 mm
 Shank type: hexagonal shank for secure grip in hex-compatible chucks and drivers
 Drilling method: dry drilling compatible design
 Typical applications: tile, stone, masonry, thin concrete
How to use
Mount the 12 mm diamond core bit in a drill or impact driver that accepts hex shanks, making sure the shank is fully seated and the chuck or holder is tightened. Mark the drilling point and start at low speed to establish the hole without wandering. Apply steady, moderate pressure and maintain a consistent rotational speed appropriate for the material; avoid excessive force that may overheat the bit. For prolonged cuts, pause periodically to allow cooling and to clear debris from the hole. The bit is designed for dry drilling, so do not introduce continuous water coolant; use intermittent operation and dust extraction where possible to manage dust and heat.
Usage recommendations
Use personal protective equipment including eye protection and a dust mask when dry drilling. Begin drilling at lower speed to prevent slipping on smooth surfaces and consider using a guide or template for exact positioning. For best results in very hard stone or thick masonry, perform short drilling cycles and allow the bit to cool between passes; replace the bit if significant wear reduces cutting performance.
