Diamond Plus™ Core Bits for Wet/Dry Drilling

• Diamond-tipped drill bits and core bits have been specially developed for professionals who need to drill into exceptionally hard materials such as porcelain/stoneware/stone tiles, cast iron, or fibreglass, where conventional core bits struggle. These core bits guarantee excellent performance and are characterised by great durability even with the hardest materials.
• Water saving: These core bits require only a small amount of water compared to conventional diamond drills, which require a continuous flow. Simply dip the drill bit or core bit in water at the start of each hole and then every 5 seconds during cutting.
• Clean holes: drills clean, precise holes without scratches on the perimeter.
• Durability: to ensure high durability, we use high-quality diamond for fast cutting and excellent bonding through brazing.
• Durability: body made of a resistant alloy that cannot be easily bent or distorted.
• Easy chip removal: angled slots for chip removal to provide greater leverage when removing tightly wedged material pieces.
• Universal: can be used either on angle grinders with the appropriate adapter or on a drill.
• How to use with an angle grinder:
• 1. Screw the M14 grinder adapter onto the core bit and tighten firmly with a wrench. Then lock the spindle in the angle grinder and mount the adapter directly onto the spindle; tighten firmly with a wrench.
• 2. If the tile is not attached to the wall, ensure it is secured in a clamp.
• 3. Dip the tips of the core bit in water.
• 4. Turn on the angle grinder to full speed. Slowly approach the tile holding the core bit at a 20-30° angle and apply light pressure to avoid slipping on the tile. When the core bit starts to cut into the tile creating a groove, gradually raise the core bit so that it is positioned horizontally to the tile.
• 5. Dip the core bit in water every 5 seconds.
• 6. To maximise tool life, apply light pressure and perform an oscillating circular motion during cutting.
