Abstract
The utility model relates to a polishing drill with a straight shank, which is provided with a cylindrical drill shank (1). The front end of the drill shank (1) is connected with a polishing drill bit (3) through a transition guide bar (2). The polishing drill with the straight shank is characterized in that: a main body of the drill bit (3) is in a six-prism structure; the section of the six-prism structure is in a shape of two isosceles trapezoids with upper bottoms opposite to each other; two intersectant waists surround a V-shaped filings accommodating trough (4); the top end of the drill bit (3) is provided with a vertex corner (5); and cutting edges (6) are distributed on the outer edges of the drill bit (3). The polishing drill with the straight shank has a large filings accommodating space, and a drilled hole has good finish of the hole wall and higher precision.
Description
Technical field
The utility model relates to a kind of aperture knife tool, and particularly a kind of polishing is bored.
Background technology
The polishing of prior art is bored, and drill bit is generally the triangular prism structure, and the chip space of drill margin and hole wall is less, to such an extent as to the hole inwall that processes is more coarse, when required precision is higher, can not satisfy required precision.
The utility model content
In order to overcome above-mentioned technological deficiency, the purpose of the utility model is to provide the polishing that a kind of chip space is big, machining accuracy is high to bore.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of staight shank polishing is bored; Have a cylindrical drillstock, the drillstock front end is connected with a polished rod head through the transition guide rod, and said drill main body is one or six prism structures; Its cross sectional shape is two relative isosceles trapezoids of upper base; Its two waistlines that intersect go out a V-arrangement chip pocket, and drill end has a drift angle, and cutting edge is arranged on the drill bit outer rim.
The beneficial effect of the utility model is:
The chip space that the utility model polishing is bored is big, the hole that it processed, and hole wall fineness is good, and precision is higher.
Description of drawings
The stereogram that Fig. 1 bores for the polishing of the utility model staight shank.
The front view that Fig. 2 bores for the polishing of the utility model staight shank.
The specific embodiment
Like Fig. 1, shown in Figure 2:
The staight shank polishing of present embodiment is bored; Have a cylindrical drillstock 1, drillstock 1 front end is connected with a polished rod head 3 through transition guide rod 2, and said drill bit 3 main bodys are one or six prism structures; Its cross sectional shape is two relative isosceles trapezoids of upper base; Its two waistlines that intersect go out a V-arrangement chip pocket 4, and drill bit 3 tops have a drift angle 5, and cutting edge 6 is arranged on drill bit 3 outer rims.
The chip space that the utility model polishing is bored is big, the hole that it processed, and hole wall fineness is good, and precision is higher.
Claims (1)
1. a staight shank polishing is bored, and has a cylindrical drillstock (1), and drillstock (1) front end is connected with a polished rod head (3) through transition guide rod (2); It is characterized in that; Said drill bit (3) main body is one or six prism structures, and its cross sectional shape is two relative isosceles trapezoids of upper base, and its two waistlines that intersect go out a V-arrangement chip pocket (4); Drill bit (3) top has a drift angle (5), and cutting edge (6) is arranged on drill bit (3) outer rim.
