The solid carbide body supports cutting rigidity, while the two-flute geometry provides chip space for aluminum and other suitable non-ferrous materials. Its low-friction DLC coating helps reduce aluminum adhesion and built-up edge. The tool is suitable for flat-bottom counterbores, recessed screw seats, shallow stepped holes and related precision hole-making operations where a conventional pointed drill would leave a conical bottom.<\/p>\n<div style=\"display: flex;
