The KWB 175180 core drill Single 8 cm is a tungsten carbide tipped hollow core drill designed for drilling openings in brick, concrete, marble, stone and reconstituted stone. The 8 cm diameter bore and impact‑resistant, specially hardened carbide cutting edge make it suitable for installing electrical sockets and waste pipes where precise circular holes are required.

Advantages

Carbide tipped cutting plates are brazed and heat resistant for prolonged edge life under high loads. The hollow core design removes material efficiently while the impact‑resistant construction reduces breakage when working in masonry. Supplied as a single piece in blister packaging for easy storage and handling.

How to use

Mount the core drill to a compatible drill or rotary hammer with the appropriate arbor or adapter. Mark the hole position, secure the workpiece or ensure stable support, and start drilling at low speed to position the cutter, then increase speed and apply steady pressure. Use water or recommended cooling if working in marble or dense stone to reduce heat and prolong tool life. Clear debris from the hollow core regularly to maintain cutting efficiency.

Recommendations

Use appropriate personal protective equipment (safety glasses, dust mask, hearing protection) and follow the power tool manufacturer's instructions. Match the drill mounting and arbor type to your machine before use. Avoid excessive lateral force to prevent chipping of the carbide tip.
