Description
Technical field
The utility model is related to a kind of drill bits, and in particular to a kind of high-precision spiral bit.
Background technology
Drill bit is provided on drilling machine, the effect that process component can be drilled by the rotation of drill bit,
Substantial amounts of iron filings can be generated when drilling, these iron filings can not timely repel the processing efficiency that drilling can cause drilling
It is affected, it is impossible to carry out the operation of efficient continuous drilling, the intensity that drill bit is needed when workpieces processing is fine, so
The service life of drill bit can be extended, but many chisel edge insufficient strengths, can influence drill bit subsequently drill when
The situation for bending occur is waited, affects the actual use cycle of drill bit.
The content of the invention
The purpose of this utility model is to provide that a kind of intensity is good, connects a kind of high-precision spiral bit of fastening.
The technical solution of the utility model is：A kind of high-precision spiral bit, is provided with handle of a knife, is divided into the handle of a knife
Drill bit is equipped with, setting is nested between the handle of a knife and drill bit, extruding spring is provided on the drill bit, in the extruding
Outer convex block is provided on spring, the outer convex block is welded to each other fixation with squeezing spring, is welded between the nesting and handle of a knife
Fixation is connect, locking hole is provided in the nesting.
The drill bit is equipped with cutting slot, and the cutting slot is in the ramp-like both sides for being distributed in drill bit.
The cutting slot lower end is provided with cutting tip, and the cutting tip is hexagonal structure.
The cutting tip is connected with each other with cutting slot, and impact-resistant coating is provided outside in the cutting tip.
Impact-resistant coating on the cutting tip is corundum-coating.
The utility model has the advantages that：Nesting is provided on the handle of a knife, drill bit can be allowed to be fixed in nesting,
By outer convex block and the interoperation of locking hole, drill bit can be fixed in nesting, so pass through outer convex block and locking hole
Interoperation can allow the handling enhanced convenience of drill bit that can carry out multiple replacement action, be provided on the drill bit
Cutting slot can allow drill bit timely to exclude iron filings in drilling by cutting slot when drilling so that drill bit can connect
Continuous bore operation, iron filings discharge drilling are more efficient.
