Abstract: A flat drill for boring holes through hard metals and high heat resistance materials such as hard metal and fiberglass. The flute or fluid portion forms a spade with slightly cylindrically concave faces which tend to distally converge. The cutting edges at the base of the drill have a negative rake angle, but a relatively high clearance for this type of drill. The lateral leading edges have a positive rake angle, but are strengthened by cylindrically convex flanks. Nose splits form a small but relatively keen small central burrowing edge which stabilizes the drill.
