Sandvik Alpha 330

To match the increased energy output from modern high-power rock drills in drifting and bolting, Sandvik brings further developments to the Alpha 330-- delivering straighter holes, higher penetration rates and 30 to 80 per cent more rod life. The drill string rod / bit connection features an entirely new thread design. The short thread on the hexagonal rods in the tool system result in a rigid, integrated powerpack drill string with superior resistance to bending stresses, improved bit guidance and perfect energy transfer.The sturdy thread is well guided inside the bit skirt, offering high precision in collaring -- even in complex rock formations and against uneven surfaces.
