Superdrill The integral drill rod is usually used in air-leg and hand-held rock drills. integral drill rods have the integral design of drill bits, drill rods and shank adapters. As it is long enough and is able to effectively reduce energy loss, the integral drill rod is suitable for underground mining and drilling small hole that is 26 to 45mm in diameter. When the rock is soft, using integral drill rods can speed up the drilling process. The integral drill rods have the advantages of reducing energy loss, improving drilling effect and efficiency.
Specifications of integral drill rod:
• Easy to remove the integral drill rod instead of removing the drill bit, which avoids breakage, cracking of drill bit and breakage of the conical end of drill rod;
•High spindle speed, with the utilization rate of the percussive force 18% to 25% higher than using separate drill bits;
• The worn bit end of the integral drill rod can be re-used as the conical drill bit after polishing.
