Description
Technical field
The utility model relates to a kind of drill bit, and particularly a kind of double end timber bores.
Background technology
drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Though reamer and counterbit can not be holed on solid material, also they are included into drill bit one class traditionally.Cutter on brill, drilling machine, drilling machine.Hole can be caused on workpiece or rock.What drill bit carried out shear action is its head, its cutting edge part and chisel edge are as cutter in action.For making that the taper seat of cutting tip does not encounter workpiece and with relief angle, the value of relief angle, suitably will be selected according to workpiece material.
Places a lot of in the manufacturing process of furniture needs to carry out punch operation, and punching mainly manufactures interface in order to plate fitment, and the type of present plate type part punching mainly contains: bolt hole, pan, connector aperture etc., general board-like parts all need punching.Because general board-like parts all need punching, and punching quantity is many, and specification is not of uniform size, needs frequent more bit change, cause very burden to work in drilling operation.
Summary of the invention
The technical problems to be solved in the utility model is to provide one double end timber brill easily, its innovative point is: comprise drillstock, drill body A and drill body B, described drillstock is a cylindrical rods, it has a keyway, and its two ends respectively have the groove that is convenient to drill body plug-in mounting; Described drill body A and drill body B is inserted into drillstock both sides, it has some cutting edges, forms chip area between described cutting edge and cutting edge.
Further, described drill body A model is M8, and described drill body Type B number is M10.
The utility model has the advantage of:
(1) a kind of double end timber of the utility model bores, and a drillstock is provided with two drill bodies, cost-saving and space; Drill body and drillstock detachably, are convenient for changing drill bit, cost-saving, at utmost utilize resource.
(2) two drill bodies are the drill body of different size, just can get the drill bit of two kinds of different sizes with a drill bit, M8 and M10 is the drill bit of common two profiles number.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that a kind of double end timber of the utility model bores.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of double end timber to bore, comprise drillstock 1, drill body A2 and drill body B3, drillstock 1 is a cylindrical rods, it has a keyway 4, drill body A2 and drill body B3 is positioned at drillstock 1 both sides, it has some cutting edges 5, forms chip area 6 between cutting edge 5 and cutting edge 5.Drill body A model is M8, and drill body Type B number is M10.
Suitable drill body 2,3 is chosen according to the size in the hole that will bore, be plugged on drillstock 1 both sides, selected drill body 2 is used to punch, after punching terminates, transfer to next place's punching place, use the drill body 3 of opposite side to start punching, after punching terminates, drill body 2,3 can be changed according to the size in concrete hole again.
More than show and describe general principle of the present utility model and principal character.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
