Detailed Description
The following detailed description of the present invention is provided to facilitate further understanding of the invention.
Fig. 1 is a schematic view of the L-groove cement drill of the present invention. Fig. 2 is a cross-sectional view a-a of the L-slot cement drill of fig. 1. Fig. 3 is a schematic view of the drill bit of the L-groove cement drill of the present invention. As shown in the figure:
the utility model provides a L groove cement bores, include drilling rod 1 with set up in the working segment 2 of 1 front end of drilling rod, chip groove 3 has been seted up on the working segment 2, chip groove 3's cell type is the L shape, the front end of working segment 2 is provided with drill bit 4, drill bit 4 extends forward and forms the head of toper structure, the head comprises a plurality of inclined plane interconnect, the contained angle of head is 130 degrees.
Preferably, the head of the drill 4 is constituted by a plurality of inclined faces of different angles. The present invention preferably includes at least a first inclined surface 41, a second inclined surface 42, and a third inclined surface 43. Of course, the present invention is not limited thereto, and one skilled in the art can select a plurality of different slopes as needed.
The included angle of the tail part of the drill rod 1 is 130 degrees. The head of the drill 4 has an opening for the head to be inlaid with the alloy. The working section 2 and the drill rod 1 are arranged integrally, and the outer surfaces of the working section and the drill rod are provided with polishing layers.
