This tool is used in core holes with 25 mm cutting depth. For low-wear work, even under heavy use, the core drill with a bare surface is made of HSS Co5 steel. The drill with a Weldon shaft diameter of 19 mm, 2 take-away surfaces and RotaQuick® lowering for a quick tool change works as quickly as precisely as it is pined: only a thin ring is chipped and the drill core is pushed out by spring force via a guide and ejector pin. To keep the risk of breakage minimal, the core drill leads the chipboard material directly upwards. Thanks to this combination, even larger diameters require relatively little force when drilling core.
