Abstract
The invention relates to the technical field of drill bit design, in particular to a multi-step taper triangle shank drill. The drill comprises a drill shank and a drill bit, wherein the drill shank and the drill bit are arranged integrally. An installing end head in a polygon prism shape is fixedly connected to the end, away from the drill bit, of the drill shank. A disassembling groove is formedin the connecting portion between the installing end head and the drill shank. A circle of check ring used for retaining the drill bit from drilling too far is integrally arranged on the connecting portion of the drill bit and the drill shank. Compared with the prior art, the multi-step taper triangle shank drill has the beneficial effects that the structure is simple, design is reasonable, by arranging the multi-step drill bit, thin steel plates with the thickness within 3 mm can be drilled, one drill bit is used for replacing multiple drill bits, holes with different diameters can be machined according to needs, large holes can be machined at a time, the drill bit does not need to be replaced, a locating hole does not need to be punched, and use is very convenient.
Description
technical field [0001] The invention relates to the technical field of drill bit design, in particular to a triangular shank drill with multi-step taper. Background technique [0002] An electric drill is a drilling tool that uses electricity as power. It is a conventional product in electric tools, and it is also the most demanded electric tool product. The annual production and sales volume accounts for 35% of China's electric tools. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, drives the working device through the transmission mechanism, and drives the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. . It is widely used in the reinforcement of building beams, panels, columns, walls, etc., and the installation of decoration, wall installa...
