Abstract
The utility model discloses a self-advancing wood drill which comprises a drill handle, a drill bit body, sawdust discharge grooves, a cutting edge, a top tip and a blade point. The drill handle is connected with the drill bit body in an integrate mode. The drill bit body is provided with a plurality of spiral sawdust discharge grooves. The cutting edge provided with the blade point is arranged on the end socket of the drill bit body. The top tip is arranged at the center of the end face of the drill bit body and provided with threads. The cutting edge is at an oblique angle of 5-15 degrees. The blade point is 1-2mm higher than the cutting edge. Due to the fact that the top tip is arranged in the middle of the top of the drill bit body, precise location can be realized. The top tip is provided with the threads so that the top tip can automatically enter a punched hole, and therefore time and labor are saved, strong stability is realized in a drilling process, and potential safety hazards are reduced. The plurality of sawdust discharge grooves arranged on the drill bit body enables sawdust to be discharged smoothly. The cutting edge is arranged at the oblique angle so that sawdust can be cut conveniently, and drilling efficiency is improved. The blade point is arranged to be higher than the cutting edge according to the design to reduce abrasion of the cutting edge and guarantee degree of finish. The self-advancing wood drill is novel in design and convenient to use.
Description
Technical field
The utility model relates to a kind of drill bit, especially a kind of self-advancing type carpenters auger.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and can the cutter of existing hole reaming often be used in daily life, has brought many convenience for our life.At present, carpenters auger is used widely in the timber repairs profession, and in the prior art, common carpenters auger structure is too oversimplified, and the drill bit end is top without arranging, and can't locate accurately fast when object is holed, poor stability, skid easily and may damage the operator, have very large potential safety hazard, when boring, can not hole by self-action, need to consume more energy, inefficiency, general drill bit may bore too many without the device of the design control hole degree of depth during punching, can't reach the demand of construction, bore good hole without fineness, more coarse, bring many troubles and problem.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of accurate positioning, high, the labour-saving self-advancing type carpenters auger of efficient.
For achieving the above object, the technical solution of the utility model is:
