Description
Technical Field
The utility model relates to a cutter field is used in the processing of auto industry engine oil pump, especially relates to a ladder drill bit of taking axial angle of processing stainless steel.
Background
Because the product characteristic and customer require to design the multi-step drill bit, process stainless steel material usually, the drill bit design all adopts the fluted drill design, increases sharpness, is favorable to cutting light and fast. However, when the drill bit disclosed herein is designed into a conventional twist, the step portion is likely to be broken when the cutting edge is sharp during use due to the fact that the number of steps is large and the interval between the steps is too small. If the straight fluted drill is designed into a conventional straight fluted drill, the strength of the cutting edge can be ensured, but the cutting edge is too thick and blunt and is not beneficial to cutting.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple structure, processing convenient to use through increasing axial angle on the chip groove of straight flute, has guaranteed the ladder drill bit of the axial angle of the processing stainless steel of the sharpness of drill bit and the intensity of blade simultaneously.
The technical scheme of the utility model, a take shoulder drill of axial angle of processing stainless steel, including drill bit main part and drill spindle, the drill bit main part correspond set up in drill spindle one side and formula structure as an organic whole set up, drill bit main part surface is provided with two cutting edges, the cutting edge is straight cutting edge, the setting of stair structure is adopted to link one side of cutting edge, corresponds respectively between two cutting edges and is provided with the chip groove, the chip groove is the straight flute fluting, the chip groove is provided with an axial inclination in the axial.
In a preferred embodiment of the invention, the axial inclination of the flutes is 12-15 °.
In a preferred embodiment of the present invention, the included angle between the two cutting edge ends is 140 °.
In a preferred embodiment of the present invention, the diameter of the drill body is 8.76 mm.
In a preferred embodiment of the present invention, the diameter of the drill body step is 10.8 mm.
In a preferred embodiment of the present invention, the diameter of the drill shaft is 14 mm.
For a ladder drill bit of area axial angle of processing stainless steel, the utility model discloses simple structure, processing convenient to use through increase axial angle on the chip groove of straight flute, has guaranteed the sharpness of drill bit and the intensity of blade simultaneously.
