Technical field
The present invention relates to mechanical processing cutter fields, more particularly to cold step drill in a kind of shank grooving lap guard bits
Head.
Background technology
It is directed to difficult Material Processing stainless steel, toughness foot, subland drill multiple-cutting-edge portion is due to its special construction, in cutting process
It is not easy chip breaking, is easily wound at handle of a knife so as to cause iron filings, need artificially to clear up, influences to process beat and easy scratching fingers.
Invention content
It is at low cost the invention mainly solves the technical problem of providing a kind of simple in structure, it is easy to make, it effectively prevent iron
Bits winding improves the interior cold subland drill of the shank grooving lap guard bits of product processing efficiency.
In order to solve the above technical problems, one aspect of the present invention is：A kind of shank grooving lap guard bits are provided
Interior cold subland drill, including cutter shaft and cutter head, the cutter head be correspondingly arranged in cutter shaft one end, and the diameter of the cutter head is small
In the cutting edge for being correspondingly arranged on multiple helical structures in the diameter of the cutter shaft, the cutter head, multiple cutting edges it
Between be correspondingly arranged on chip space, oil groove is also correspondingly arranged on the cutter shaft, the oil groove includes the first oil groove of cutter shaft side
With the second oil groove of cutter shaft shank, first oil groove and the second oil groove correspond to connection setting, one end of first oil groove with
The chip space is correspondingly connected with, and interior cold trap is also correspondingly arranged in the cutter shaft and is correspondingly arranged with oil groove.
In a preferred embodiment of the present invention, first oil groove is provided with two.
In a preferred embodiment of the present invention, two articles of first oil grooves are symmetrically disposed on cutter shaft both sides and respectively with
The both ends of two oil grooves are correspondingly connected with.
In a preferred embodiment of the present invention, one end of the interior cold trap it is corresponding with the first oil groove connection, the other end with
Second oil groove corresponds to connection.
In a preferred embodiment of the present invention, the interior cold trap is correspondingly arranged on two.
In a preferred embodiment of the present invention, two interior cold traps twist structure setting.
The beneficial effects of the invention are as follows：The configuration of the present invention is simple, it is at low cost, it is easy to make, it effectively prevent iron filings to wind, carries
High product processing efficiency.
Description of the drawings
Fig. 1 is the front view of the interior cold first preferred embodiment of step drill of shank grooving lap guard bits of the present invention；
Fig. 2 is the right view of Fig. 1.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
It please refers to Fig.1 and combines Fig. 2, the embodiment of the present invention includes：A kind of interior cold subland drill of shank grooving lap guard bits, packet
Cutter shaft 1 and cutter head 2 are included, the cutter head 2 is correspondingly arranged in 1 one end of cutter shaft, and the diameter of the cutter head 2 is less than the cutter shaft 1
