Browse our dry diamond core drills and adaptors in various sizes ranging from 22mm to 200mm. Diamond core drills from Black Diamond are robust and built to last under high-pressure applications. Ensure the diamond core drill is suitable for the application you intend to use it for (material drilled and machine used for drilling- check individual product description). When using our diamond core drills, first use a tungsten tipped bit to make the pilot hole and when direction of hole is imperative use the tungsten tipped bit to follow through to the entire depth before using the diamond core drill. Assemble the correct adapter, guide rod and diamond core drill and then insert into chuck of drill machine. Then make sure the chuck is tightened as much as possible. Ensure you are comfortable and secure before beginning. Put the guide into your pre-drilled pilot hole and start the machine. Slowly introduce the core drill to the material in a gentle motion. Make sure the machine is held rigidly to avoid deviation from the correct direction of drilling. As you drill, make sure there is no debris blocking the hole, which can cause jamming.  Equally important is to check for glazing on the segment or stress cracks on the barrel. When removing the core material from the diamond core drill, point the core drill downwards. If the material does not fall out then remove the adapter and insert a rod through the fitting and gently tap to remove.
