Abstract
The utility model discloses a multifunctional drill for tiles, which comprises a drill stem (1) and a drill bit (2) fixedly connected with the drill stem (1), wherein the drill bit (2) comprises a tip (6), a first main blade edge (3), a first accessory blade edge (4), a second main blade edge (5) and a second accessory blade edge, and a buffer angle Theta (7) is formed by the second main blade edge (5) and a first plane (8) of the drill bit (2). The multifunctional drill for tiles not only is capable of drilling on tiles and concrete, but also drilling on cast iron parts, high-hardness alloy steels and the like.
Description
Technical field
The utility model relates to a kind of drill bit, specifically is a kind of multifunctional tile drill bit.
Background technology
At present, when interior decoration or exterior finish, can use drill gun to be holed in the body of wall or the floor that are pasted with ceramic tile usually.The employed drill bit of these drill guns is special drill bit, and its structure generally comprises drilling rod and drill blade, and the end welding of described drill blade and drilling rod is fixing.The name that discloses a publication number and be CN101428451 on China national intellectual property website is called the patent of " drill for tile ", comprise drilling rod and bore cutter, boring cutter is the pentagon body, bore on the cutter and include point of a knife, first major cutting edge, first auxiliary-blade, second major cutting edge and second auxiliary-blade, the angle of described first major cutting edge and drilling rod center line is 40 °-45 °, and the angle of second major cutting edge and drilling rod center line is 65 °.This drill for tile is when the rotary cutting ceramic tile, for the first time eating input by the cutting of first major cutting edge cuts, and then eating input by the cutting of second major cutting edge cuts, so just reduce the cutting resistance in the two major cutting edge working angles, be difficult for to produce vibrations when making the drill bit rotary cutting, it is inner and can not make the ceramic tile fragmentation because of vibrations to make things convenient for drill bit to creep into ceramic tile.The drill for tile of this structure also comes with some shortcomings in actual applications, because we may get into inner high rigidity things such as metal reinforcing bar, ironcasting or steel alloy when the body of wall that is stained with ceramic tile or concrete are holed.When drill bit gets into these high rigidity things, after first major cutting edge cutting, and then eat input when cutting by the cutting of second major cutting edge, can make the drill blade fracture of rotation at a high speed because the cutting cushion effect between two major cutting edges is little.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provide a kind of and not only can on ceramic tile and concrete, hole, and the multifunctional tile drill bit that can on ironcasting, high hardness alloy steel etc., hole.
Technical solution of the present utility model is, a kind of multifunctional tile drill bit with following structure is provided: it comprises drilling rod and the drill blade of fixedlying connected with drilling rod, described drill blade includes point of a knife, first major cutting edge, first auxiliary-blade, second major cutting edge and second auxiliary-blade, and first plane of described second major cutting edge and drill blade is formed with buffering angle θ.
After adopting above structure, the utility model multifunctional tile with drill bit compared with prior art has the following advantages: because first plane of second major cutting edge and drill blade is formed with buffering angle θ.After the cutting of first major cutting edge, and then eat input when cutting by the cutting of second major cutting edge, because first plane of second major cutting edge and drill blade is formed with buffering angle θ, cutting cushion effect between two major cutting edges is increased, the drill blade of rotation can not rupture when getting into the high rigidity thing at a high speed, so this multifunctional tile not only can be holed on ceramic tile and concrete with drill bit, and can on ironcasting, high hardness alloy steel etc., hole.
As preferably, described buffering angle θ is 8 °～12 °.Stock-removing efficiency can be do not reduced like this, drill blade can be do not damaged yet because cushion effect between two major cutting edges is too small because cushion effect between two major cutting edges is excessive.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.
The utility model multifunctional tile drill bit, it comprises drilling rod 1 and the drill blade 2 of fixedlying connected with drilling rod 1, described drill blade 2 includes point of a knife 6, first major cutting edge 3, first auxiliary-blade 4, second major cutting edge 5 and the second auxiliary-blade (not shown), and described second major cutting edge 5 is formed with buffering angle θ 7 with first plane 8 of drill blade 2.
Described buffering angle θ 7 is 8 °～12 °.
Angle between described first major cutting edge 3 and second major cutting edge 5 is 118 °～130 °.
Claims (2)
1. multifunctional tile drill bit, it comprises drilling rod (1) and the drill blade (2) of fixedlying connected with drilling rod (1), described drill blade (2) includes point of a knife (6), first major cutting edge (3), first auxiliary-blade (4), second major cutting edge (5) and second auxiliary-blade, it is characterized in that: described second major cutting edge (5) is formed with buffering angle θ (7) with first plane (8) of drill blade (2).
2. multifunctional tile drill bit according to claim 1 is characterized in that: described buffering angle θ (7) is 8 °～12 °.
