## Long description

The Dedra H1241 diamond core bit is designed for drilling accurate circular holes in concrete and stoneware. With a 102 mm outer diameter and a 75 mm inner diameter, this core bit cuts precise cores for installations where clean, consistent openings are required. It is suitable for use with compatible drill rigs and rotary tools that accept these diameters and is intended for professionals and experienced DIY users working on building services and renovation tasks.
Advantages
The diamond-segment cutting edge offers high abrasion resistance and maintains cutting performance when working with dense materials such as concrete and stoneware. The concentric inner diameter supports stable core removal and reduces stress on the drill during operation. The designed geometry improves hole roundness and minimizes chipping on brittle surfaces, delivering repeatable results for through-holes and service penetrations.
Suitable for
Creating service penetrations for plumbing and sanitary installations
Drilling openings for electrical conduits and cable routes
Forming ventilation and HVAC pass-throughs in walls and floors
Renovation work requiring precise circular cutouts in concrete or stoneware
Key specifications
Outer diameter: 102 mm
Inner diameter: 75 mm
Material suitability: concrete, stoneware
Cutting edge: diamond segments for abrasive materials
Intended mounting: compatible with drill rigs and rotary tools accepting the specified diameters
How to use
Select a drill or rig that accepts the Dedra H1241 diameters and ensure the tool is rated for diamond core drilling. Secure the workpiece and, where possible, use a guide or template to maintain perpendicular entry. Start drilling at low speed to seat the bit, then increase to the tool’s recommended speed while applying steady, even feed pressure. Use water cooling or a controlled lubrication method if the drill and material allow it, to reduce heat and prolong cutting life. After completing the cut, withdraw the core bit carefully and remove the core.
Usage recommendations
Use appropriate personal protective equipment, including eye protection, dust mask or respirator, hearing protection and gloves. Match drilling speed and feed to the host material and apply water cooling when feasible to extend segment life and improve cut quality.
