Drill Bit Montolit MONTOLIT KORONA MONDRILLO BLACK 8 mm FSB08 (dry/wet drilling)

Diamond core drill bit Montolit KORONA MONDRILLO BLACK 8 mm FSB08 is a compact, high-precision tool designed for making small, clean holes in hard surfaces. Engineered for both dry and wet drilling, it provides controlled cutting performance for tiles, ceramics and natural stone. The 8 mm diameter and reinforced black-coated body ensure compatibility with standard drill chucks and steady operation during repetitive use in renovation and installation tasks.

Advantages

The drill bit features a diamond-segment cutting edge that enables precise, burr-free holes with minimal chipping on glazed tiles and porcelain. Its construction supports both wet and dry methods, allowing flexibility depending on the working environment. The compact 8 mm size offers accurate starts and good access to tight areas, while the durable coating improves wear resistance and extends tool life under normal professional or DIY use.

Suitable for

• Drilling holes in glazed and unglazed ceramic tiles
• Creating openings in porcelain and vitrified tile
• Making precise holes in natural stone and similar hard materials
• Tile installation, plumbing fixtures and small electrical pass-throughs

Key specifications

• Cutting material: diamond-segment edge for hard materials
• Drilling diameter: 8 mm
• Operation modes: suitable for dry and wet drilling
• Shank type: compatible with standard drill chucks
• Coating: black protective finish for improved wear resistance

How to use

Secure the workpiece and mark the drilling position. Fit the drill bit into a compatible drill chuck and ensure it is tightened correctly. For dry drilling, use controlled feed pressure and moderate speed to avoid overheating; pause periodically to allow cooling. For wet drilling, apply steady water flow or use a suitable cooling system to reduce dust and heat and to extend diamond segment life. Start drilling at low speed to establish a precise entry point, then increase speed as required while maintaining steady pressure.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. When drilling with water, protect electrical tools and connections from moisture. Choose wet drilling for prolonged work on hard or abrasive tiles to maximize bit life; use intermittent drilling and gentle pressure for dry operations to reduce risk of glazing damage.
