Abstract

PROBLEM TO BE SOLVED: To prevent oil from running short by providing a groove around a drill body. SOLUTION: By providing a groove with an angle around a drill body to which oil is put, this groove acts as a pump when the drill is rotated, and oil is fed into a hole while cutting the hole, and a great effect is gained in cutting a deep hole and durability of a knife edge is improved. A conventional drill runs short of oil as hole cutting proceeds, and durability of a knife edge and cutting performance are poor. This device was made to solve these problem of running short of oil and durability. To explain this referring to drawings, a groove with an angle (2) into which oil is put is provided around a portion of a relief of the edge of the drill body (1). With this structure, the drill body is mounted on a machine for use, and a cutting oil is flowed into the drill body as the conventional drill.

Conventional drills run out of oil as the depth of hole cutting gradually increases, and the cutting edge lacks durability and machinability. The present invention was devised to eliminate this oil shortage and durability. This will be described with reference to the drawings. Angled oil-containing grooves (2) are formed around the nig portion of the blade of the drill body (1). Since the present invention has such a structure, when this is used, the drill body may be attached to the machine and cutting oil may be poured into the drill body to be used in the same manner as a conventional drill.
