Core Drill Bit for Concrete AWTools Korona 80 x 100 mm SDS+ (AW40518)

AWTools Korona core drill bit for concrete, size 80 x 100 mm with SDS+ shank is designed to create large, clean boreholes in concrete and reinforced concrete. The cylindrical body and durable cutting edge provide stable cutting performance when used with SDS+ rotary hammer drills. Intended for installation tasks that require accurate circular openings, this core bit produces consistent hole edges and efficient material removal for plumbing, electrical and HVAC penetrations.

Advantages

The design combines a hardened cutting rim with a robust cylindrical body to deliver long tool life and improved hole quality. Compatibility with SDS+ chucks allows quick installation and secure retention in hammer drills. The geometry of the cutting edge reduces vibration and helps maintain alignment during drilling, while the hollow core enables faster extraction of the concrete plug.

Suitable for

• Drilling circular openings for plumbing pipes and drains in concrete walls and floors
• Creating passages for electrical conduits and cable routing
• Making holes for mechanical anchors and fasteners in reinforced concrete
• Installing ventilation ducts and service penetrations in masonry

Key specifications

• Drill type: core (hollow) drill bit for concrete
• Material compatibility: concrete and reinforced concrete
• Diameter: 80 mm
• Working length: 100 mm
• Shank type: SDS+ for use with SDS+ rotary hammer drills
• Body: cylindrical hollow core for plug removal
• Cutting edge: hardened rim for improved wear resistance

How to use

Fit the AWTools Korona core drill bit into the SDS+ chuck of a compatible rotary hammer according to the drill manufacturer's instructions. Mark the hole position and, if possible, start drilling at low speed to establish the center, then apply steady pressure using the hammer function appropriate for concrete. Use periodic withdrawal of the core bit to clear debris and, for deep or extended work, cool the bit by clearing dust or using water if the drill and the application permit wet drilling. After reaching the required depth, stop the tool and remove the core plug by pulling out the hollow segment or tapping it out as needed.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and dust mask or extraction when dry drilling. Match drill speed and hammer settings to the base material and avoid excessive lateral force to prolong tool life. For reinforced concrete, inspect for rebar and proceed with controlled cutting; where applicable, consider using water for dust suppression and cooling if the tool and jobsite conditions allow.
