A key feature provided is the precision threaded Cap-to-Tube system virtually eliminating lateral runout at the drilling face of the core bit.;This allows the bit to spin more precisely without a loping effect that commonly occurs due to an uneven Cap to tube weld.;More precise running bits mean quicker penetration and drilling while also decreasing segment side wear and drag.;Wet bits are standard 15 cutting depth.;Designed for use on mast mounted core rigs.
