Description
Technical Field
The utility model relates to a boring cutter technical field specifically is a small hole boring cutter.
Background
A boring cutter is one of boring tools, and is generally used for hole machining and reaming. When the boring cutter is used for processing a small hole, the diameter of the cutter bar extending into the hole to be processed is required to be smaller due to the smaller aperture of the small hole, so that the strength of the cutter bar is reduced, the boring cutter is easy to break, economic loss is caused, and the invention of the small hole boring cutter is necessary for solving the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pinhole boring cutter to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an aperture boring cutter, includes hilt portion and cutting edge portion, cutting edge portion connects the upper end at hilt portion, the cutting edge portion top sets up to unilateral shaping sword tooth, and the shaping sword tooth that sets up can cut the aperture, the top of shaping sword tooth is provided with the tool bit, be provided with the chute on the tool bit, the tool bit adopts carbide to make, and intensity is difficult for the fracture greatly.
Preferably, the cutting head is provided with a forming corner portion extending radially outwards.
Preferably, a slope is provided on the back surface of the cutting edge portion.
Preferably, the shank portion is cylindrical in shape, and the shank portion has a diameter larger than the diameter of the cutting edge portion.
Compared with the prior art, the beneficial effects of the utility model are as follows: this aperture boring cutter, reasonable in design, simple structure, this product are novel aperture boring cutter, including hilt portion and cutting edge portion, the cutting edge portion top is unilateral shaping sword tooth, and shaping sword tooth top tool bit is radial shaping bight that extends outwards, and this product is specifically exclusively used in high rigidity such as titanium alloy, and the spare part processing of high accuracy has intensity height, processes accurate advantage.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
