Abstract
The utility model aims at providing a drill with replaceable cutting blades. The drill comprises a drill handle and a blade portion which is installed on the end portion of the drill handle. The drill is characterized in that a plurality of clamping grooves are formed in the end face of the front end of the blade portion, and the cutting blades are inlaid in the clamping grooves. The cutting blades of the drill are inlaid in the clamping grooves of the blade portion of the drill, so that when the cutting blades are worn, only the cutting blades are required to be replaced, the whole drill is not required to be discarded, and the cost is saved.
Description
Technical field
The utility model belongs to the bit technique field, specially refers to a kind of drill bit of replaceable cutting edge.
Background technology
In the use of drill bit, its cutting edge can wear and tear gradually, can't continue to use until cutting edge again.Because cutting edge and the drill bit of conventional drill are integrally manufactured, therefore after cutting edge lost efficacy because of wearing and tearing, drill bit will go out of use, and has caused great waste like this.
The utility model content
The purpose of this utility model is the drill bit that proposes a kind of replaceable cutting edge.
Drill bit of the present utility model comprises drillstock and is installed in the blade of drillstock end that key is that the front end end face of described blade is provided with several draw-in grooves, is inlaid with cutting edge in the described draw-in groove.
Because the cutting edge of above-mentioned drill bit is to be embedded in the blade draw-in groove of drill bit, therefore after the cutting edge wearing and tearing, can only changes cutting edge, and need not whole drill bit is discarded, thereby save cost.
Further, described draw-in groove radially distributes, and the angle angle between the adjacent draw-in groove is identical.Like this in when boring, all cutting edges stressed identical, therefore the degree of wearing and tearing can be consistent, and finally can change all cutting edges simultaneously, rather than change certain cutting edge, can guarantee the performance of drill bit like this.
Drill bit of the present utility model is inserted by cutting edge is changed into, can change when cutting edge weares and teares, and need not whole drill bit is discarded, thereby save cost.
Description of drawings
Fig. 1 is the structural representation of drill bit of the present utility model.
Fig. 2 is the structural representation of the blade front end end face of drill bit of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the drill bit of present embodiment comprises drillstock 1 and is installed in the blade 2 of drillstock 1 end that the front end end face of described blade 2 is provided with several draw-in grooves 3, is inlaid with cutting edge 4 in the described draw-in groove 3.
Because the cutting edge 4 of above-mentioned drill bit is to be embedded in the blade draw-in groove 3 of drill bit, therefore after cutting edge 4 wearing and tearing, can only changes cutting edge 4, and need not whole drill bit is discarded, thereby save cost.
Further, as shown in Figure 2, described draw-in groove 3 radially distributes, and the angle angle between the adjacent draw-in groove 3 is identical.Like this in when boring, all cutting edges 4 stressed identical, therefore the degree of wearing and tearing can be consistent, and finally can change all cutting edges 4 simultaneously, rather than change certain cutting edge 4, can guarantee the performance of drill bit like this.
Claims (2)
1. the drill bit of a replaceable cutting edge comprises drillstock and the blade that is installed in the drillstock end, it is characterized in that the front end end face of described blade is provided with several draw-in grooves, is inlaid with cutting edge in the described draw-in groove.
2. drill bit according to claim 1 it is characterized in that described draw-in groove radially distributes, and the angle angle between the adjacent draw-in groove is identical.
