Abstract
The utility model relates to a machining tool, an efficiency of work is improved quick chamfer specific drill bit of durable type, the main part comprises the straight shank drilling rod and the cutting body, its characterized in that: the straight shank drilling rod is the cylinder, be equipped with U type groove on the straight shank drilling rod, can dispel the heat, increase of service life, the cutting body is the toper, be equipped with cutting blade on the cutting body, the cutting blade front end is equipped with bullet form alloy head, cutting blade excessive wear anyway.
Description
Technical field
The utility model relates to a kind of semi-finished machining tool, particularly a kind of durable type quick chamfering target drill of increasing work efficiency.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on processing work, and can to the cutter of existing hole reaming.Drill bit is used in a lot of field, comprise machinery, drilling well, medical, timber, stone, glass etc., and chamfering special jewel is a kind of semi-finished machining tool, for removing the burr that boring stays in the air later, also can be used for water caltrop and wears into chamfering.
Utility model content
The purpose of this utility model is a kind of durable type quick chamfering target drill of increasing work efficiency.
A kind of durable type quick chamfering target drill of increasing work efficiency, main body is made up of staight shank drilling rod and cutting body, its innovative point is: described staight shank drilling rod is cylinder, described staight shank drilling rod is provided with U-type groove, described cutting body is taper, described cutting body is provided with cutting blade, and described cutting blade front end is provided with bullet shaped alloy head.
Further, the length of described staight shank drilling rod is 5 ~ 10cm, and the length of described cutting body is 10 ~ 15cm.
Further, described cutting blade is taper.
Further, described cutting blade front end is provided with bullet shaped alloy head.
Further: described staight shank drilling rod has U-type groove.
The beneficial effects of the utility model are:
1, staight shank drilling rod described in the utility model, through quenching technical process, sturdy and durable, has certain toughness, not fragile, and through glossing, meet the aesthetic standard of people.
2, the utility model drill bit is provided with cutting blade, and the design of the angle that cutting blade is carried out and structure, can be good at accelerating cutting speed, increase work efficiency.
3, cutting blade front end described in the utility model is provided with bullet-shaped alloy head, can prevent cutting blade excessive wear, increase the service life.
4, staight shank drilling rod described in the utility model has the U-type groove of heat radiation, can increase the service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is the cutting end view of the utility model drill bit.
Detailed description of the invention
Straight shank drill as shown in Figure 1, by staight shank drilling rod 1, cutting body 2, cutting blade 3, bullet shaped alloy head 4, U-type groove 5.
The structure of straight shank drill is as shown in Figure 1: drilling rod 1 is cylinder, and the length of drilling rod is 5 ~ 10cm, and handling and the use of straight shank drill are mainly considered in the design of this structure, too shortly not easily installs, oversize poor stability.
One end of straight shank drill is cutting body 2 as shown in Figure 1, and cutting body 2 is provided with cutting blade 3, and described cutting blade front end is provided with bullet-shaped alloy head, reaming speed can be accelerated, and cutting blade excessive wear can be prevented, increase work efficiency, increase the service life.
Described staight shank drilling rod 2 has U-type groove 5, and during processing work, drill bit fast rotational, can accelerate the discharge of heat, increase the service life.
During processing work, staight shank drilling rod 1 is contained on electric hand drill, aims at the boring held successfully, first slowly rotate, allow bullet shaped alloy head be introduced in boring, then slowly accelerate rotary speed, the burr of drill hole inner wall just can be got rid of; And water caltrop to be worn into chamfering be with cutting blade 3 near processing work, first slowly rotary drilling-head, determines the angle needing to grind off, then accelerates rotary speed, repeatedly polish up and down, through after a period of time, so just passable.
The above is preferred embodiment of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
