Triangular alloy tool bit

Abstract

The invention relates to a triangular alloy tool bit, and aims to mainly solve the technical problems that an existing alloy tool bit is nearly all linear, is lower in cutting operation benefit and the like. The triangular alloy tool bit is characterized by comprising a first cutting edge, a second cutting edge and a third cutting edge which are circularly and uniformly distributed and arrayed to form a whole, wherein the inner sides of the first cutting edge, the second cutting edge and the third cutting edge are higher than the outer sides of the first cutting edge, the second cutting edge and the third cutting edge, so that the upper ends of the first cutting edge, the second cutting edge and the third cutting edge are respectively inclined. The triangular alloy tool bit disclosed by the invention has the beneficial effects that by arranging the first cutting edge, the second cutting edge and the third cutting edge, when a drill bit operates, an electric drill drives the drill bit to rotate by one circle, and then cutting output of one cutting edge can be correspondingly increased compared with an existing drill bit, so that cutting benefits of the drill bit can be remarkably improved by one third, the operation time is correspondingly shortened by using the triangular alloy tool bit under the same workload; as the operation time is shortened, the service life of the drill bit can be effectively prolonged.

Description

technical field [0001] The invention relates to a cutting tool, more specifically to a triangular alloy cutter head, which is mainly used in the field of hardware tools such as drill bits. Background technique [0002] The alloy cutter head is a necessary part of the existing hardware tools. The existing alloy cutter head for the drill bit is basically in-line shape, and it is fixed on the end of the drill rod by welding to form a drill bit with two cutting edges, left and right. The electric drill drives the rotation of the drill bit to achieve drilling or cutting operations. As we all know, if there are more alloy cutter heads in the drill bit, the cutting efficiency will be higher. However, due to the limitation of processing conditions, it is impossible to process triangular or pentagonal cutter heads on the head of the drill pipe. Mounting groove, therefore, what the existing hardware tool industry all adopts is the inline alloy cutter head. Contents of the invention...
