Earth-drilling tool

A drill-bit comprising:

• a head comprising a face and a gage;
• the face comprising a plurality of face button bits;
• the gage comprising a plurality of gage button bits evenly spaced around the head;
• a plurality of major chip gage gashes evenly spaced around the head;
• a plurality of minor chip gage gashes evenly spaced around the head;
• a plurality of face flushing holes;
• a plurality of gage flushing holes;
• the plurality of major chip gage gashes alternating with the plurality of minor chip gage gashes around the head;
• and
• one of the plurality of gage button bits disposed in-between every set of the alternating major chip gage gashes and minor chip gage gashes;
• wherein a first axis extending through centers of the plurality of face flushing holes is perpendicular to a second axis extending through centers of the plurality of gage flushing holes.

A method of using a drill-bit comprising:

• rotating the drill-bit to cut material with a plurality of face button bits and a plurality of gage button bits, the plurality of gage button bits evenly spaced around a head of the drill-bit;
• flowing air through a plurality of face flushing holes and through a plurality of gage flushing holes;
• and
• flushing the material cut by the drill-bit through a plurality of major chip gage gashes evenly spaced around the head, and through a plurality of minor chip gage gashes evenly spaced around the head, the plurality of major chip gage gashes alternating with the plurality of minor chip gage gashes around the head, one of the plurality of gage button bits disposed in-between every set of the alternating major chip gage gashes and minor chip gage gashes, and a first axis extending through centers of the plurality of face flushing holes being perpendicular to a second axis extending through centers of the plurality of gage flushing holes.
