Abstract
The utility model discloses an auger bit which aims to provide a machinery carpenter's auger with a new structure and comprises an auger head and an auger handle which are connected into integration. The anger head body of the anger head is a helical cutting part, and the end part of the anger head is provided with an anger tip, a circumferential cutting edge and a main cutting edge; the anger tip is a conical screw, the circumferential cutting edge is in a circular arc shape, and the anterior angle of the main cutting edge is from 30 DEG to 80 DEG. Because the anger tip is the conical screw, the anger tip can perform a centralized positioning function, and forward pull force is generated to make the anger tip automatically feed and reduce the labor intensity. In addition, because the helical angle of the helical cutting part of the auger head body is smaller than that of the general carpenter's auger, the anterior angle of the main cutting edge is enlarged, the cutting edge is much sharper, and the cutting is much handier than that of the general carpenter's auger; the utility model has little wasted work and smooth drilled hole walls; therefore, the auger work on wood can be finished with rapidness, labor saving and high quality.
Description
Technical field
The utility model belongs to the wood working tool technical field, particularly the boring drill bit of carpenter.
Background technology
Present used carpenter, cutting front end face central point is the rectangular pyramid body of a protrusion, the front end face excircle has the circumference cutting edge, two main cutting edges are arranged in the middle of the front end face, because the particularity of mechanical carpenter structure, the anterior angle of general main cutting edge is sharpening not, and big, though relief angle through sharpening, is not very big to the cutting influence.Therefore, poor performance is cut in this structure carpenter's drilling, and slow, the inefficiency of big, the feed speed of axial resistance during boring, labour intensity are big, drill bit easily generates heat.
The utility model content
The purpose of this utility model is, overcomes the structural shortcoming of above-mentioned solid center bit, provides a kind of carpenter of new construction to use zhiluo drill.
In order to address the above problem, the utility model is achieved through the following technical solutions: zhiluo drill includes drill bit and drillstock fuses, the bit body of its drill bit is a spirality blade, there are apex point, circumference cutting edge, main cutting edge in the end of drill bit, it is characterized in that apex point is a conical screw, the circumference cutting edge is a circular arc, and the anterior angle of main cutting edge is between 30 °-80 °.
According to the zhiluo drill of such scheme system, because apex point is a conical screw, can play centralized positioning, also can produce a pulling force forward, make the drill bit auto-feed, alleviated labour intensity.In addition, because the helical angle of bit body spirality blade reduces than general carpenter, make the anterior angle of main cutting strengthen, make cutting edge sharper, the general carpenter of cutting ratio is lighter and handier, therefore wasted work is little, and the hole wall that gets out is bright and clean, can be not only not only laborsaving but also can finish driller's operation in high quality soon.
Description of drawings
Fig. 1 is the front view of zhiluo drill.
Fig. 2 is the left view of zhiluo drill.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1, Fig. 2 are the structural representations of zhiluo drill.Zhiluo drill has drill bit 1 and drillstock 2 to fuse, and the upper semisection of drillstock 2 is six prisms, and lower semisection is a cylinder, is the hexagonal drillstock, and according to different installation way, the form of drillstock can also be SDS type, quick-change type drillstock, to make things convenient for the clamping of drillstock.The bit body 3 of its drill bit 1 is a spirality blade, and there are apex point 4, circumference cutting edge 5, main cutting edge 6 in the end of drill bit, and apex point 4 is conical screws, and circumference cutting edge 5 is a circular arc, and the anterior angle of main cutting edge 6 is 45 °.26 ° of the helical angles of bit body spirality blade.
Claims (2)
1, zhiluo drill includes drill bit and drillstock fuses, the bit body of its drill bit is a spirality blade, and there are apex point, circumference cutting edge, main cutting edge in the end of drill bit, it is characterized in that apex point is a conical screw, the circumference cutting edge is a circular arc, and the anterior angle of main cutting edge is between 30 °-80 °.
2, zhiluo drill according to claim 1 is characterized in that between 20 °-50 ° of the helical angles of described bit body spirality blade.
