Concrete Core Bit AWTools Korona HEX 65 x 100 mm (AW40519)

Diamond-tipped concrete core bit AWTools Korona HEX 65 x 100 mm is designed for drilling clean circular holes in concrete, reinforced concrete and similar masonry materials. With a 65 mm diameter and 100 mm cutting depth, this core bit is suitable for creating openings for pipes, conduits, cable glands and anchor points. The HEX shank ensures secure mounting in compatible rotary tools and core drills, reducing slippage during intensive work.

Advantages

The diamond-segment cutting edge provides efficient material removal and prolonged service life when used on hard masonry. A precisely manufactured cylindrical body and balanced cutting segments deliver straight, accurate holes with minimal breakout. The HEX shank design improves torque transfer and prevents rotation in chucks that accept hexagonal shanks, enhancing safety and tool control. The core bit is suitable for both professional tradespeople and informed DIY users who require consistent performance.

Suitable for

• Drilling holes for plumbing and HVAC pipe installations
• Creating openings for electrical conduits and cable entries
• Installing anchor bolts and fixing points in concrete structures
• Making passage holes for drainage or ventilation ducts

Key specifications

• Cutting diameter: 65 mm
• Cutting depth: 100 mm
• Tip material: diamond segments
• Shank type: HEX (hexagonal)
• Compatible materials: concrete, reinforced concrete, masonry

How to use

Mark the drilling position and ensure the workpiece is stable and supported. Use a rotary hammer or core drill that accepts HEX shanks, clamp the core bit securely and set the tool to the appropriate rotation speed and feed pressure for concrete. Begin drilling with light feeding to establish the pilot contact, then maintain steady pressure and coolant or periodic water flushing if applicable to reduce heat and clear debris. Withdraw the bit occasionally to remove the inner core and check progress. After reaching the required depth, stop the tool before removing the bit to avoid chipping the hole edges.

Usage recommendations

For optimal performance and tool life, use water cooling or intermittent drilling to control heat buildup and remove dust. Wear appropriate personal protective equipment including eye protection, hearing protection and a dust mask or extractor. Verify compatibility of the HEX shank with your drill chuck or adapter before use and follow the drill manufacturer's instructions for safe operation.
