Abstract
The invention relates to a double-bit wood drill. The double-bit wood drill comprises a drill handle, a drill bit body A and a drill bit body B, wherein the drill handle is a columnar rod, a key groove is formed in the drill handle, and the two ends of the drill handle are both provided with grooves convenient for the drilling bit bodies to be inserted therein; the drill bit body A and the drill bit body B are inserted into the two sides of the drill handle respectively, and both the drill bit body A and the drill bit body B are provided with a plurality of cutting edges, and chip removing grooves are formed between the cutting edges. The double-bit wood drill has the advantages that the two drill bit bodies are installed on the drill handle, and the cost and the space are saved; the drill bit bodies and the drill handle are detachable, the drill bits are convenient to replace, the cost is saved, and the resources are used to the greatest extent; the types of the two drill bit bodies are different, two drill bits with different types can be machined by one drill bit, and M8 and M10 are two commonly seen types of drill bits.
Description
Technical field
The present invention relates to a kind of drill bit, 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 problem to be solved in the present invention 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 invention has the advantages that:
(1) a kind of double end timber of the present invention 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 present invention bores.
Detailed description of the invention
As shown in Figure 1, the invention 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 invention and principal character.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
Claims (2)
1. a double end timber bores, and it is characterized in that: comprise drillstock, drill body A and drill body B, described drillstock is a cylindrical rods, it has a keyway, 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.
2. a kind of double end timber according to claim 1 bores, and it is characterized in that: described drill body A model is M8, and described drill body Type B number is M10.
