Hand drill and method of use

A hand drill for rotating a cutter, the hand drill comprising:

• a housing having a motor therein, the housing having a first end and a second end;
• a chuck extending from the first end of the housing, the chuck being driven by the motor to rotate the cutter around an axis;
• a first planar surface of the housing extending between the first and second ends, the first planar surface being parallel to the axis and spaced a first predetermined distance from the axis;
• and
• a guidance groove in the first planar surface, the guidance groove being parallel to the axis.

A method for drilling a hole in a workpiece, the method comprising the steps of:

• a) providing a cutter;
• b) providing a hand drill for rotating the cutter, the hand drill comprising:
• a housing having a motor therein, the housing having a first end and a second end;
• a chuck extending from the first end of the housing, the chuck being driven by the motor to rotate the cutter around an axis;
• a first planar surface of the housing extending between the first and second ends, the first planar surface being parallel to the axis and spaced a first predetermined distance from the axis;
• and
• a guidance groove in the first planar surface, the guidance groove being parallel to the axis and located on a line formed by the intersection of a plane that passes through the axis and is perpendicular to the first planar surface;
• c) locking the cutter in the chuck;
• d) providing a planar work surface having a guidance ridge;
• e) fastening the workpiece in a predetermined position with respect to the planar work surface and the guidance ridge;
• f) positioning the hand drill on the planar work surface such that the first planar surface contacts the planar work surface, the guidance ridge engages the guidance groove, and the cutter is pointed towards the workpiece;
• and
• g) sliding the hand drill across the planar work surface, along the guidance ridge, until the cutter cuts the desired hole in the workpiece.

• a pair of alignment bores in the first planar surface, the pair of alignment bores being positioned such that a line through the pair of alignment bores is parallel to the axis;
• and
• a pair of alignment studs, each of the pair of alignment studs having an insertion end and a protruding end, the insertion end of each of the pair of alignment studs fitting into one of the pair of alignment bores;
• c) locking the cutter in the chuck;
• d) inserting the insertion end of each of the pair of alignment studs into one of the pair of alignment bores of the hand drill;
• e) providing a planar work surface having a linear terminal edge;
• f) fastening the workpiece in a predetermined position with respect to the planar work surface and the linear terminal edge;
• g) positioning the hand drill on the planar work surface such that the first planar surface contacts the linear terminal edge, the pair of alignment studs each abut the planar work surface, and the cutter is pointed towards the workpiece;
• and
• h) sliding the hand drill along the linear terminal edge, keeping each of the pair of alignment studs in contact with the planar work surface, until the cutter cuts the desired hole in the workpiece.
