A seismic drilling bit designed for insertion for use in enlarging an upper end of a pre-drilled hole for receiving and securely retaining an anchor therein. The bit is rotatably mounted onto a drill or can be mounted onto a mounting assembly which in turn is rotatably mounted to the drill. The upper end of the bit has cutting portions positioned on each side of the upper end which have a greater cutting radius than that of the bit body whereby, when the bit is inserted fully into an uppermost end of the pre-drilled hole and rotated, by means of the drill, the cutting portions enlarge a circumference of the pre-drilled hole at the uppermost end that is greater than that of the pre-drilled hole. In this manner, an anchor can be inserted within the pre-drilled hole, and, when the anchor has been flanged outwardly by conventional means within the hole, the flange portions of the anchor will rest within the enlarged area, thus securely retaining the anchor in place.
