Problems solved by technology

[0002] Nowadays, when producing machined products, the drill bit is an indispensable tool. When the drill bit is used at high speed, it generates a lot of heat, and the blade often breaks, mainly because the heat of the blade cannot be discharged in time, which adds extra to the enterprise. production cost

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] A drill bit with cooling holes on the blade, such as figure 1 , as shown in Figure 2, it includes a drill body 1, a blade 2, and a cooling hole 3; the blade 2 is at one end of the drill body 1, the cooling hole 3 is on the blade 2, and the cooling hole 3 runs through each blade , That is to form a drill bit with cooling holes on the blade.

[0014] The specific operation is as follows: first, put the drill body 1 into the equipment, and when the equipment is turned on, the blade 2 processes the product to be processed, and the heat generated is dissipated from the heat dissipation hole 3 on the blade 2 and the drill body 1, Therefore, the heat on the blade portion 2 is reduced at the fastest speed, and the service life of the blade portion 2 is increased.

[0015] In the present invention, as a variant embodiment, the shape of the cooling holes may be circular...

Abstract

The invention relates to a drill bit with a radiating hole in a blade part. The drill bit comprises a drill bit main body, the blade part and the radiating hole, wherein the blade part is arranged at one end of the drill bit main body; the radiating hole is formed in the blade part: the radiating hole penetrates through the whole blade part. The drill bit with the radiating hole in the blade part provided by the invention has an excellent radiating property and long service life. The abandonment of the products is greatly reduced.

Description

technical field [0001] The invention relates to a drill bit, in particular to a drill bit with cooling holes on the blade. Background technique [0002] Nowadays, when producing machined products, the drill bit is an indispensable tool. When the drill bit is used at high speed, it generates a lot of heat, and the blade often breaks, mainly because the heat of the blade cannot be discharged in time, which adds extra to the enterprise. production cost. Contents of the invention [0003] The object of the present invention is to provide a drill bit with cooling holes on the blade, which overcomes the deficiencies of the prior art. [0004] In order to achieve the above-mentioned technical purpose, the technical solution adopted by the present invention is: a drill bit with heat dissipation holes on the blade, which is characterized in that it includes a drill body, a blade portion, and heat dissipation holes; the blade portion is at one end of the drill body, and the heat di...
