MIRCALE Integral Drill Rods
Integral rods are used by hand held rock drill in granite and marble quarries, underground mining, for small blasting hole drilling shank H22x108mm, H19x108mm, and standard hex. Bit diameters include 20-42mm, different lengths are available from 400mm to 8000mm usually. With the same steels as Sandvik and best carbides made in China, we are supplying different lengths of integral drill rods with different head diameters.
Parameters
• Shank size: Hex.19 x 108mm, Hex.22 x 108mm, Hex.19 x 82mm
• Head diameter: 26mm to 42mm.
• Length: 400 - 8000mm.
Features
• Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;
• 23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material.
• Cost-effective, good performance with reasonable price.
• Complete types of drill rod for various drilling scenarios.
• 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.
Applications
Drilling duties in tunneling, construction, mining, quarrying, etc.
