Abstract
The utility model relates to a twist drill, particularly relates to a dual-head twist drill and belongs to a mechanical processing tool. The dual-head twist drill comprises a drill handle and drill bodies, the drill handle and the drill bodies are manufactured into a whole, and spiral chip removing grooves are opened on the drill bodies. The dual-head twist drill is characterized in that the two drill bodies are arranged at two ends of the drill handle respectively. According to the dual-head twist drill, the two drill bodies are arranged at the two ends of the drill handle respectively, so that when one drill body is abraded, the other drill body can be reversed for usage, and expenses of at least one drill body can be saved.
Description
Technical field
The utility model relates to a kind of fluted drill, particularly relates to a kind of double end fluted drill, belongs to a kind of machine tools.
Background technology
Fluted drill be rotary cutting by its relative fixed axis with the instrument of the circular hole of drilling workpiece, gain the name because its chip area curl is similar to fried dough twist.Fluted drill comprises all-in-one-piece drillstock processed and drill body, has spiral chip area on the drill body.The fluted drill of prior art is single head, namely only has a drill body, and drill body whole fluted drill after wearing and tearing all will be scrapped, and has caused like this waste.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and the double end fluted drill that a kind of reasonable in design is provided, use saves.
The technical scheme in the invention for solving the above technical problem is: a kind of double end fluted drill, comprise all-in-one-piece drillstock processed and drill body, and have spiral chip area on the drill body, be characterised in that: described drill body is two, is separately positioned on the two ends of drillstock.
The utility model has anti-slip tank at described drillstock.
The utility model compared with prior art has following advantage and effect: drill body is two, is separately positioned on the two ends of drillstock, and such drill body has worn and torn, and can fall to use another drill body, has saved the expense of at least one drillstock; Have anti-slip tank at drillstock, can prevent from skidding after drillstock is by the chuck clamping of machine.
