Integral Drill Rods

Maxdrill’s 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 24 to 44mm in diameter. The integral drill rod is usually used in air-leg and hand-held rock drills. When the rock is soft, using Maxdrill’ 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.

Highlights High spindle speed, with the utilization rate of the percussive force 18% to 25% higher than using separate drill bits; 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; The worn bit end of the integral drill rod can be re-used as the conical drill bit after polishing. Basic information Length: 400mm to 8000mm for various applications Size of the end: Hex.25mm, Hex.22mm Bit diameter: 30mm to 44mm Package: in pallet or in bundles Productivity: 20,000psc/month
