The sharpness of the angle is simply enhanced, the chip containing angle of the drill bit is small, unsmooth chip removal can occur, the drill body and a processed product are extruded, and the bad phenomena of blackening of the drill body, deformation of the drill body, falling of a blade, breakage of the drill body and the like can occur.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at: the problem of the not smooth chip removal appears easily when using to current alloy blade formula carpenter's drill bit, provides a carpenter and uses alloy drill bit, and this drill bit promotes the chip removal ability through improving the helicla flute angle, and bad phenomena such as fracture appear when reducing the drill body and using.
In order to realize the purpose, the utility model discloses a technical scheme be:
the alloy drill bit for the woodworker comprises a drill body, wherein one end of the drill body is provided with a handle part, the other end of the drill body is provided with an alloy cutter head, a cutting part is arranged on the alloy cutter head, spiral grooves are formed in the drill body and the alloy cutter head, and the angle of each spiral groove is 25-30 degrees.
The utility model discloses an increase the drill bit helix angle for 25-30, strengthened the chip removal ability of helicla flute, adopt whole alloy tool bit sharpening to form the cutting portion simultaneously, can increase alloy tool bit blade helicity, promote the blade sharpness ability, further promote drill bit chip removal effect to solve current drill bit appear boring the body when using blackened, bore the body deformation, the blade drops, bore bad phenomena such as body fracture.
As the preferred scheme of the utility model, there is circular main cutting edge both ends about the cutting portion, and the bottom center is equipped with the location cutting edge. By adopting the design, the spiral degree of the cutting edge of the alloy cutter head is better, the sharpness of the tooth edge is improved, the chip removal effect of the drill bit is improved, the centering effect is better, and deviation is not easy to generate during drilling.
As the utility model discloses a preferred scheme, alloy tool bit is as an organic whole with boring body tip welding to improve the joint strength of alloy tool bit and boring the body, make the alloy tool bit be difficult for droing.
As the preferred proposal of the utility model, the handle part is a straight handle, the processing is convenient and the cost is low.
As the preferred scheme of the utility model, be equipped with the fixed plane on the excircle of stalk portion to fasten the drill bit stalk portion through the side pressure mode.
As the utility model discloses a preferred scheme, the stalk portion is connected with adjusting screw in the one end of keeping away from the brill body to the height of convenient when installation regulation drill bit.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
the utility model discloses an increase the drill bit helix angle for 25-30, strengthened the chip removal ability of helicla flute, adopt whole alloy tool bit sharpening to form the cutting portion simultaneously, can increase alloy tool bit blade helicity, promote the blade sharpness ability, further promote drill bit chip removal effect to solve current drill bit appear boring the body when using blackened, bore the body deformation, the blade drops, bore bad phenomena such as body fracture.
