Abstract
The utility model belongs to the field of drill bits and particularly discloses a welding alloy drill. The drill comprises a drill bit handle, wherein a drill bit connecting part is arranged at one end of the drill bit handle, a drill bit positioning part is arranged at the other end of the drill bit handle, the drill bit connecting part is welded with an alloy drill body, a drill tip is arranged at one end of the alloy drill body, and a drilling cutting baffle is arranged on the circumferential surface of a position wherein the alloy drill body is connected with the drill bit connecting part. The drill has the advantages that cuttings can be blocked by the drilling cutting baffle, and the cost can be saved by a welded drill bit.
Description
Technical field
The utility model belongs to drill bit field, and specifically a kind of welding alloy bores.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and cutter that can be to the reaming of existing hole.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Used common drill bit is generally used material for carbide alloy and high-speed steel, the drill bit made from Hardmetal materials, although durable in use, price is very high, and the outside diameter of producing can not surpass φ 20mm, production and application cost is high, and the drill bit made from high-speed steel, although low price, use cost is relatively cheap, but due to the low easy fracture of drill bit rigidity of high speed steel material, so use cumbersomely, often change.
Summary of the invention
The utility model, for the weak point existing in above-mentioned technology, proposes a kind of welding alloy and bores, and by the mode of welding, saves use cost.
The utility model provides following technical scheme:
Welding alloy bores, and it comprises drill handle part, and drill handle part one end is provided with drill bit connecting portion, the other end is provided with drill bit location division, drill bit connecting portion is welded with alloy drill body, and alloy drill body end is provided with apex point, and the side face of alloy drill body and drill bit connecting portion junction is provided with drilling cuttings baffle plate.
Described apex point is provided with alloy blade.
Described drill bit location division is comprised of tapered portion and cylindrical portion.
The utility model has the advantages that by drilling cuttings baffle plate and can block chip, the drill bit of welding can be saved cost simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, welding alloy bores, it comprises drill handle part 1, drill handle part 1 one end is provided with drill bit connecting portion 2, the other end is provided with drill bit location division 3, drill bit connecting portion 2 is welded with alloy drill body 4, and alloy drill body end is provided with apex point 5, and alloy drill body 4 is connected 2 places side face with drill bit connecting portion is provided with drilling cuttings and keeps off 6 plates.
Described apex point is provided with alloy blade 7.
Described drill bit location division forms b by tapered portion a and cylindrical portion.
