Symptom:Loss of diamond segment Cause:a.diamond core drill bit too hard for the material it is drilling, causing it to pound and fatigue.            b.Overheating due to insufficient water for cooling and flushing.            c.Machine setup is not rigid or loose material is in the cut and the bit segment hangs.            d.Shooting cable, when drilling pre-stress. Remedy:a.Use a softer bond for diamond core drill bit if possible.  Increase motor RPM if possible.              b. Increase water flow to where slurry is milky and flows easily.              c.Tighten anchor, check vacuum system for proper vacuum pressure.              d.Use a bit with more segments, such as a  pre-stressed diamond core bit Concrete core drill bit

The application fields of vacuum brazed diamond tools 1. Suitable for DIY cutting in the western families,for it’s universal specialities. 2. Could use in strong cutting,drill,and expecially in the special spot like fire emergency,for the coherence and high convexity of diamonds. 3. Could cut the materials which is easily blocked like resin wind-power blade,ferrous metal materials,for its ample place for scraps 4. Cutting efficiently of concret which with high density of rebars,castiron pipe by government,two side rebars on the tracks high speed rail 5. For the super hard granites,ceramics and other materials which could not be easily cut by the electroplated/sintered diamond tools.

What is diamond core drill bit or hole saws Diamond core drill bits are one kind of diamond tools which are used in making holes on the stone,glass,concrete,tile, such as granite, marble,sandstone,green concrete reinforcing steel bars(rebar),cured concrete,etc. They can be classfied by making way as below: 1. Laser welded diamond core drill bit 2. Silver brazed diamond core drill bit 3. Electroplated diamond core drill bit or diamond coated diamond core drill bit 4. Vacuum Brazed diamond core drill bit With different shank, they can be used on CNC machines such as 1/2" GAS,etc. Diamond core drill bit

Diamond hole saws are also called diamond core drill bits . 1. Laser welded diamond core drill bits can be used in wet and dry drilling, but not all materials to be drilled are suitable for dry drilling. Very hard materials like reinforced  concrete, normally should be drilled with water, otherwise the excessive heat generated during the drilling process may cause the diamonds on the core bit to become blunt, and then lead to poor drilling performance. The situation is just like concrete diamond blades for reinforced concrete cutting. 2. Silver braed diamond core drill bits are most used in wet condition, if not, the diamond segment will be dropped off from the core because of the heat caused by drilling hard materials such as hard concrete,granite,marble,tile,etc. 3. Electroplated diamond core drill bits are mosted used in wet condition also for cutting,drilling marble,granite,tiles,glass,etc. 4. Vacuum Brazed diamond core drill bit can be used in dry condition. Because ...

1. Diamond core drill bit 2. The application of diamond core drill bit drilling of holes in optical and industrial glass and other non metal materials · Diamond layer is made of diamond powders and micropowders in electroplated bonds · Usage of coolant is obligatory. Diamond core drill bit

Diamond drilling is the most productive method of making a hole in friable, hard, nonmetallic materials. The most com monly used in industry are tubular drills consisting of a diamond rim crown, fixed in a cylindrical core (drill end). These tools take off material only on the rim surface. Usage of drills of this type helps to reduce axial load and to ease coolant supply to the cutting area. It provides high productivity and quality of processing and decreases diamond expenses.
