Abstract
The utility model discloses a three-blade auger bit, aiming at providing the three-blade auger bit which has simple structure, easy drilling and high efficiency. The three-blade auger bit consists of a conical spiral point, main cutting blades, minor cutting blades, a cutter body, a spiral flute and a hilt and is characterized in that the spiral flute is provided with three ends; the number of the main cutting blades and the number of the minor cutting blades are three; and the front end of each minor cutting blade is provided with a circumference cutting blade which is higher than the main cutting blade. The three-blade auger bit has the advantages that as the number of the spiral flute is three, and the number of the main cutting blades and the number of the minor cutting blades are three, the speed for cutting and chip-removing can be fast. When in drilling, the outer circumference of a hole can be cut by the circumference cutting blades before the cutting of the main cutting blades, and the wall of the hole is smooth, therefore, the drilling operation can be completed fast with less labor and high quality.
Description
Technical field
The utility model belongs to wood working tool, particularly three boring sword Zhiluo drillers of carpenter.
Background technology
Used carpenter is made up of spiral shell point, two major and minor cutting edges, cutter hub and twin-feed spiral grooves mostly at present.But because the carpenter cutting output is big, feed speed is fast, tends to take place the chip removal difficulty for higher feed speed, the drilling resistance is big, drill body heating, the phenomenon that inefficiency even hole wall burn.
The utility model content
The purpose of this utility model provides a kind of simple in structure, three sword Zhiluo drillers light, that efficient is high of holing.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: comprise by taper spiral shell point, main cutting edge, front cutting edge, cutter hub, spiral grooves and handle of a knife, it is characterized in that described spiral grooves is three, main cutting edge and front cutting edge respectively have three, are shaped on the circumference cutting edge that exceeds main cutting edge at the front end of every front cutting edge.
The advantage of this three swords Zhiluo driller is: because spiral grooves is three, major and minor cutting edge respectively has three, and therefore, cutting and chip removal speed are fast.During boring, the circumference cutting edge has cut the excircle that portals before main cutting edge cutting, and the hole wall that gets out is bright and clean, so can be not only not only laborsaving but also can finish bore operation in high quality soon.
Description of drawings
Fig. 1 is the front view of three sword Zhiluo drillers;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, spiral shell point; 2, main cutting edge; 3, front cutting edge; 4, cutter hub; 5, spiral grooves; 6, handle of a knife; 7, positioning groove; 8, circumference cutting edge.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
It comprises by the handle of a knife 6 of taper spiral shell point 1, three main cutting edges 2, three front cutting edges 3, cutter hub 4, three spiral grooves 5 and positive six prisms, is shaped on circumferential circular arc positioning groove 7 on the handle of a knife 5.Front end at every front cutting edge 3 is shaped on the circumference cutting edge 8 that exceeds main cutting edge 2.
Claims (3)
1. three sword Zhiluo drillers, comprise by taper spiral shell point, main cutting edge, front cutting edge, cutter hub, spiral grooves and handle of a knife, it is characterized in that described spiral grooves is three, main cutting edge and front cutting edge respectively have three, are shaped on the circumference cutting edge that exceeds main cutting edge at the front end of every front cutting edge.
2. three sword Zhiluo drillers according to claim 1 is characterized in that described handle of a knife is positive six prisms.
3. three sword Zhiluo drillers according to claim 1 is characterized in that being shaped on the described handle of a knife circumferential circular arc positioning groove.
