electroplated diamond drill diamond drill known as casting, is made by plating the principle of diamond drill bits. Diamond carcass in the plating tank in the plating layer by layer on the drill bit body, electrolytic metal plating covering the same time, spreading the diamond particles, the diamond was wrapped in a metal plating layer inside. Prolonged and repeated patch of sand to form a plating layer of drill work. Electroplating drill steel body also uses plastic mold shaping, the coating along the axis of the drill bit growth, and to ensure that the inner and outer carcass size and small ducts. Diamond drill bits are used mostly artificial diamond diamond drill carcass composition is mainly nickel, and ordinary impregnated diamond bits have the same conditions of application
carbide drill is a drill core drilling used. On a cylindrical drill bit body of steel welded tungsten carbide inserts because of carbide cutting tools named. And its shape on the drill bit inserts welded carbide cutting tools of the number, arrangement, different inserts welded angle, called the end of the blade, and the blade within the blade out to ensure that there is a gap through the water and the discharge of the powder. The upper portion of the drill bit body is threaded connection core pipe, drill bit body side opened a sink, the bottom surface of the lip also opened outlet. Sink and outlet are to ensure the flow of irrigation fluid, reach excluded rock dust and cool the drilling bit. In order to increase the gap in the inner and outer side walls of the hard alloy drill welded on the drilling clay and shale formations ribs, said ribs drills. In the highly abrasive formations can be hard to use autogenous grinding tungsten carbide drill bits. Usually hard alloy drill drilling rock drillability is a Ⅶ grade Ⅱ formation; tungsten carbide drill bits drilling Ⅵ Ⅷ stage a rock.
1. material can be suitable for more complex drilling, choose a higher cutting speed.
2. Featured alloy drill dedicated high-performance alloy blades, effectively reduce chipping, good wear resistance.
3. multilayer geometry cutting edge end, increase the excretion of performance, maintain a smaller cutting resistance.
4. In addition to the usual rectangular handle, the handle a wide range, suitable for a variety of drilling machines, drilling machines equipped with
