Drill attachment - Alpha 330
The Sandvik Alpha 330 utilizes a new short thread construction that enhances drilling and collaring accuracy. This thread design, along with new hexagonal rods, gives the tool a robust drill string specially suited for 43 mm to 51 mm drilling operations.The drill string is capable of creating more linear bores, for enhanced drilling patters and hole precision. This also allows for more efficient use due to reduced downtime and minimized tooling costs.
