Eccentric Overburden Drilling System Concentric casing system with blocks is applicable to all kinds of core drilling rig, bolt rig, for geological exploration, deep foundation pit support, high slope anchorage, tunnel collapse tube shed support, pebble layer high pressure rotary jet and other fields 1. Eccentric Reamer System Step-by-step 1) When drilling starts, the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit

Symmetric Overburden Drilling System The symmetric drilling system is designed to drill and case a hole simultaneously through unstabled ground conditions. The driver bit incorporated with a satisficial ring or reusable ring makes a full face head design which significantly improves the penetration rate and hole straightness of drilling. The internal flushing grooves together with the built-in casing shoes gives a good seal to the button of the drilling hole, and thus

Forging Blast Hole Threaded Drill Rod with R32 / R38 / T38 / T45 / T51 Thread Drill rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system. Mainly Products: Thread Drill Bits---Diameter: 51mm to 127mm Thread
