Abstract
The invention relates to a disposable multi-edge twist drill which is characterized in that a. the twist drill with more than four edges (containing four edges) is named multi-edge twist drill; b. the harder the materials to be drilled are, the larger the number of twists should be, namely the larger the edge number is; c. the twists and the edges are arranged on the head portion of the twist drill, the diameter of a body portion is smaller than that of the head portion, and the aim of saving materials can be achieved; and d. the head portion of large-specification twist drill can be made as an independent portion and is movably connected with the body portion of the twist drill, the specification of the head portion is various, and the position of the head portion connected with the body portion has interchangeability. The twist drill advances with the times and is capable of reducing labor intensity, improving production effect, saving integral resources and promoting traditional transformation and upgrading. The twist drill can be applied alternatively and can be applied to a traditional twist drill.
Description
Technical field
The present invention relates to a kind of drill bit, specifically a kind of disposable multiple-cutting-edge fluted drill.
Background technology
As everyone knows, the most general traditional fluted drill is three swords, along with the continuous appearance of new material and the lifting of economic level, boring and drill bit has also been had Secretary; In general, cutting output within the unit interval is relevant with the sword number of blade, and certainly, the cutting ability of fluted drill and durability have many factors to determine, under the prerequisite that guarantees the total quality of fluted drill own, sword number and the sharpening technology of fluted drill blade are decisive factors.
Summary of the invention
The invention provides a kind of disposable multiple-cutting-edge fluted drill, and then reach the requirement that adapts to industry development and grow with each passing hour.
Technical scheme of the present invention is:
1. the above fluted drill (containing four swords) of four swords, we are called multiple-cutting-edge.
2. the material of being holed is harder, and the quantity of fried dough twist should be more, and namely the sword number of blade is more.
3. be provided with fried dough twist and blade by the head at fluted drill, body section diameter can be made less than head diameter, and then reaches the purpose of material-saving;
4. the fluted drill of large specification can be made the fluted drill head an independently part, takes the mode of loose joint to connect with the body section of fluted drill, and the head specification can be multiple, and there is interchangeability at the position that connects with body section.
5. the present invention can use in conversion, is included in the application on traditional fluted drill.
The present invention grows with each passing hour, and can reduce labour intensity, improves the production effect, saves whole resource, promotes tradition upgrading transition.
The specific embodiment
In the age backward in economy, a fluted drill is necessary recycling, and in the age of economic development and lifting, labour cost is sometimes much higher than fee of material, and the present invention is exactly an example, in other words, and disposable growing with each passing hour; The sword number is more, the specification requirement of whetting a knife is higher, generally be difficult to reach requirement by artificial or aid, so above fluted drill of four swords, should be take disposable use as main, disposable multiple-cutting-edge fluted drill, only the head at fluted drill is provided with fried dough twist and blade, body section diameter can be made less than head diameter, and then reaches the purpose of material-saving; The original-pack drill bit that dispatches from the factory is than handy many of artificial reconditioning drill bit out, and this itself has just improved effect; The drill bit of large specification can be made drill bit head an independently part, takes the mode of loose joint to connect with the body section of drill bit, body section can reuse, the head specification can be multiple, and there is interchangeability at the position that connects with body section, and the saving here is significant; The present invention can use in conversion, is included in the application on traditional fluted drill.
