## Long description

AWTools Korona HEX 80 x 100 mm diamond core bit is designed for efficient drilling in concrete. With an 80 mm outer diameter and a 100 mm cutting depth, this core bit creates precise circular holes for plumbing, electrical conduits, anchors and other installation needs. The HEX shank ensures secure grip and fast tool changes in compatible rotary or core drilling machines, while the diamond segment cutting edge is made for cutting through reinforced and plain concrete.
Advantages
The AWTools Korona HEX core bit provides clean borehole edges and consistent cutting performance. Its HEX shank reduces slippage in chucks and adapters, enabling stable rotation under load. The diamond-segmented rim offers increased wear resistance and a longer working life when used with correct drilling technique and cooling. The 100 mm cutting depth allows through-holes for most standard installations without the need for multiple passes.
Suitable for
 Drilling holes for plumbing pipes in concrete walls and floors
 Creating passages for electrical conduits and cable ducts
 Preparing holes for anchors, fixings and dowels
 Core drilling when installing HVAC components or services
Key specifications
 Outer diameter: 80 mm
 Cutting depth: 100 mm
 Shank type: HEX
 Material: diamond-segment cutting rim suitable for concrete
 Intended material: reinforced and plain concrete
How to use
Secure the core bit in a compatible rotary or core drilling machine with a HEX-compatible chuck or adapter. Mark the centre of the hole and, where possible, use a drill stand or guide to maintain perpendicular alignment. Begin drilling at low speed to establish the pilot contact, then increase speed and apply steady pressure. Use continuous water cooling or intermittent flushing to remove slurry and prevent overheating of the diamond segments. Withdraw the bit periodically to clear debris when drilling deep holes.
Usage recommendations
Use appropriate personal protective equipment, including eye and hearing protection and dust control measures. Ensure the drilling machine and bit remain cool by using water cooling or pauses as needed. Match drilling speed and feed pressure to machine power and concrete hardness to optimise bit life and hole quality.
