Tips
When choosing the right diamond drill bit, several factors are important:
• Diameter of the core drill bit – depending on the desired hole size.
• Wet or dry drilling – wet drilling prevents overheating and extends life, while dry drilling is suitable for jobs without water supply.
• Type of material – concrete, reinforced concrete, brick,stone, or tiles each require a specific drill bit.
• Connection – check the connection (1-1/4" UNC or 1/2" BSP) to ensure the drill bit fits your core drilling machine properly.
