Further, the cutting surface is made of special steel materials;

through above-mentioned technical scheme, improve the intensity of cutting face, and then increase life.

Further, a first screw is connected with one side wall of the special steel in a threaded manner;

through the technical scheme, the special steel can be further fixed through the first screw.

The utility model has the following beneficial effects:

1. compared with the existing straight shank glass drill, when the straight shank glass drill is put into use, the special steel is welded at the joint of the second handle and the glass drill main body, so that the strength of the joint can be improved, the condition that the joint is broken in long-term use is avoided, and meanwhile, the cutting surface is designed to be the special steel, so that the service life of the glass drill main body can be further prolonged.

2. Compared with the traditional straight shank glass drill, the straight shank glass drill provided by the utility model has the advantages that the first handle and the second handle can be conveniently removed through the first threaded pipe, the second threaded pipe, the round hole, the second screw and the nut, and the straight shank glass drill also has more convenient replacement and maintenance in the later period.

3. Compared with the existing straight shank glass drill, the straight shank glass drill with the long service life can improve the overall strength of the handle main body through the reinforcing ribs, and the reinforcing ribs can be limited and fixed under the action of the locating ring, so that the situation that the internal reinforcing ribs deviate when the straight shank glass drill is used for a long time is avoided.
