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

Always secure the drill rig either with a mechanical anchor, vacuum system or by use of the jack screw. NEVER stand on the base and drill without anchoring. Level the drill rig by use of the base leveling screws, and a small level attached to the column permanently or by a magnetic strip on the level. This procedure will ensure a perpendicular hole. Never let the bit spin in the hole without applied pressure. This will cause the diamonds to round off and the bit segments will heat and glaze over. Turn on water before starting the drill motor. Otherwise, the water jacket seals heat up and become brittle, losing water. When your bit encounters steel (rebar), relax pressure about 1/3 and allow the bit to cut at its own rate. DO NOT PUSH THE BIT. Some operators turn the water down after exiting the steel to sharpen the bit. If you engage in this practice, turn the water back up once the bit is sharpened. When drilling high PSI concrete or concrete with very hard aggregate (i.e., ri...

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

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.
