Bai NASDAQ PDC drill? Drill blades made of natural South African diamonds as a raw material and special materials carcass sintering, for drilling at f> 12 级 hard rock in providing performance guarantees. Specifications: Φ28, Φ32 PDC anchor bit ????????? Application: Suitable for drilling mining, transportation, utilities and other sectors bolting with wire mesh hole for the construction process to provide effective protection and production safety specifications: Φ25 , Φ27, Φ28, Φ30, Φ32, Φ36, Φ42 PDC core bit ????????? not efficient drilling and drainage hole, drilling escape hole, grouting holes and the Geological Prospecting Holes new tool specifications: (ordinary) Φ48, Φ56, Φ60, Φ65, Φ75, Φ94, Φ108, Φ110, Φ113, Φ133? difference matrix formula and steel body PDC drill bit PDC drill bit matrix PDC ⒈ matrix type formula PDC (PDC) bits are The PDC welding on a cutting type drill bit matrix by brazing. Sintered tungsten carbide drill bit matrix powder made of artificial polycrystalline diamond compact brazed tungsten carbide matrix, with natural diamond gage. ⒉ steel-body PDC drill steel body PDC drill bit is formed with nickel, chromium, molybdenum alloy machining. After heat treatment on drill bit body, strong synthetic polycrystalline diamond composite sheet pusher (tight fit) drill bit body, with a cylindrical tungsten carbide gage PDC drill Features:?? 1, PDC drill bit relative to other efficient , simple, durable, new product 2, PDC drill bits have a long life, under the same conditions is 10-30 times 3 carbide drill, PDC drill bit can improve efficiency, can significantly reduce the number to drill, the average aging can more than 50 percent 4, PDC drill bits suitable lithology wide drilling performance f = 1-12 rocks same level of excellence? Bai Nast diamond bit electroplated diamond drill out to solve the common problem of moles, an effective and practical, long life, good appearance, strong adaptability and so stratum. Diamond drill bits, reamers mainly used for concrete core pulling, engineering survey and bedrock drilling. Particularly suitable for medium hard, hard formation drilling! ? URL: www.hjbns.com
