Abstract
The utility model discloses a novel wood flat bit set. A flat bit set body comprises a positioning blade and a main cutting blade, a round rod is arranged on a drill body, the drill body is further provided with an inclined blade on one side of the main cutting blade, one end of the inclined blade near to the main cutting blade is a wide blade, one end of the inclined blade away from the main cutting blade is retracted to the side edge of the drill body. The novel wood flat bit set in the scheme can rapidly guide to remove chips and smear metal through the added progressive inclined blade, so that the cutting process is relatively smooth, the cutting resistance is effectively reduced, the cutting speed is increased, the service is prolonged, and the structure improvement is of substantial technical significance and has a market value.
Description
Technical field
The utility model relates to carpenter's cutting tool technical field, specifically a kind of Woodworking flat drill.
Background technology
Woodworking flat drill, perforate speed fast (being conventionally called again lightning Woodworking flat drill), is commonly used to the hole that machining accuracy is not high, and needs through thin plate.Woodworking flat drill regular size has external diameter 6mm-40mm, and common used material is No. 45 steel on the market, and hardness is accomplished HRc40-48, if better brand can be made of No. 65 steel again, hardness can be accomplished HRc45-54 like this, and cutting effect is better
Woodworking flat drill on the market, as shown in Figure 1, mainly by location sword 1, main cutting edge 2, round bar 4 and six side's handle 5 four parts form.The defects such as this traditional Woodworking flat drill exists penetration rate slow, and the life-span is low, and boring sites in curing burr is many.
Utility model content
For the problems referred to above, the utility model aims to provide and a kind ofly can improve penetration rate, increases the service life, and reduces the woodwork chit drill structure of boring sites in curing burr
For realizing this technical purpose, scheme of the present utility model is: a kind of woodwork chit drill, chit drill drill body is by locating sword, main cutting edge forms, drill body is provided with round bar, described drill body is also provided with oblique sword in a side of main cutting edge, and described oblique sword is wide sword near one end of main cutting edge, away from one end of main cutting edge, receives to drill body side.
As further improvement, the end of described round bar is provided with six side's handles.
The lightning Woodworking flat drill of this programme, by the gradual oblique sword increasing can lead rapidly chip removal and smear metal, makes working angles more smooth and easy, has effectively reduced cutting resistance, improves cutting speed, increases the service life; The improvement of this structure has substantial technical meaning and market value.
Accompanying drawing explanation
Fig. 1 is traditional Woodworking flat drill structural representation;
Fig. 2 is Woodworking flat drill structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 2, a kind of woodwork chit drill of the present utility model, chit drill drill body is by locating sword 1, main cutting edge 2 forms, drill body is provided with round bar 4, described drill body is also provided with oblique sword 3 in a side of main cutting edge 2, and described oblique sword 3 is wide sword near one end of main cutting edge 2, away from one end of main cutting edge, receives to drill body side.
Gradual oblique sword 3 can improve the penetration rate of Woodworking flat drill, extends its service life, reduces boring sites in curing burr phenomena.Tiltedly sword can also make the wood that is cut Paint Gloss, reduces follow-up deburring operation.The special negative rake design of location sword 1, main cutting edge 2 and oblique sword 3 makes chit drill be more prone to enter material, cuts curling wood chip, and the cutting of chit drill is chopped off from scraping disconnected becoming, and can cut fast the soft metals such as various hardwood, cork and aluminium.The chip breaking point design of main cutting edge 2 and tiltedly sword 3 can sharp stroke of disconnected lumber fibre.Whole working angles becomes " insert--chip breaking--cutting--volume bits--optical surface " from " insert--cutting " of traditional chit drill before.Not only obtain brighter and cleaner surface but also faster more than 30% than traditional chit drill in cutting speed.
For ease of the installation of drill body, the end of round bar 4 is provided with six side's handles 5, but the Woodworking flat drill below 8mm is generally still made round handle conventionally, without six side's handles.
The modes such as adding man-hour, the needs of the visual rigidity of surface treatment mode of Woodworking flat drill of the present utility model, select polishing, and sandblast is turned black, and electricity is chanted, titanizing are processed.In a preferred embodiment, the material of employing is that steel alloy forges and to form, and is common chit drill service life more than 2 times.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
Claims (2)
