[0022] A veneer particleboard alloy drill bit with double helix chip flutes, comprising a shank 1 and a connecting sleeve 4. The outer surface of the shank 1 is fixedly installed with a drill body 3. The outer surface of the connecting sleeve 4 is fixedly installed with a fixing member 6. Two chip flute bodies 7 are provided on the outer surface of the fixing member 6. The outer surfaces of the two chip flute bodies 7 are both provided with main cutting edges 9. A plurality of cutting members 8 are arranged on the outer surface of the fixing member 6 close to the drill body 3.

[0023] Specifically, during drilling, the fixing member 6 supports the drill body 3. The two main cutting edges 9 cut into the particleboard. At the same time, a plurality of cutting members 8 enhance the cutting force. The two chip flute bodies 7 discharge the cut chips, thereby achieving the effect of reducing the wear that easily occurs on the cutting edges of the cutting body during long-term use and improving the drilling efficiency.

[0024] In the embodiment: The shank 1 is in the shape of a hexagonal prism. The drill body 3 is a double helix thread drill bit. The fixing member 6 is in an arc shape. And a plurality of cutting members 8 are arranged in a circumferential array.

[0025] Specifically, because the shank 1 is in the shape of a hexagonal prism, the friction force for installing the shank 1 and the connecting sleeve 4 is increased. Moreover, the drill body 3 is a double helix thread drill bit, which has stronger wear resistance. And the fixing member 6 is in an arc shape, and a plurality of cutting members 8 are arranged in a circumferential array, which improves the wear resistance of the cutting.

[0026] In the embodiment: The two main cutting edges 9 are both in an arc shape. And the fixing member 6 is made of a non-ductile material. The two chip flute bodies 7 are in a spiral shape.

[0027] Specifically, because the two main cutting edges 9 are both in an arc shape, which mainly plays a role in guiding and extruding cutting. And the fixing member 6 is made of a non-ductile material. The non-ductile material reduces chipping. The two chip flute bodies 7 are in a spiral shape, which has a larger space and is conducive to chip discharge.

[0028] In the embodiment: A clamping portion 2 is fixedly installed on the outer surface of the shank 1 away from the drill body 3. And the drill body 3 is arranged at the center point of the fixing member 6.

[0029] Specifically, a clamping portion 2 is fixedly installed on the outer surface of the shank 1 away from the drill body 3, which is convenient for connecting with a drill installation device. At the same time, the drill body 3 is arranged at the center point of the fixing member 6, so that the fixing member 6 supports the drill body 3.

[0030] Working principle: A drill bit body 3 is fixedly installed on the outer surface of the shank body 1. At the same time, a fixing member 6 is fixedly installed on the outer surface of the connecting sleeve 4. In addition, two chip discharge groove bodies 7 are formed on the outer surface of the fixing member 6. Main cutting edges 9 are arranged on the outer surfaces of the two chip discharge groove bodies 7. Moreover, a plurality of cutting members 8 are arranged on the outer surface of the fixing member 6 close to the drill bit body 3. During drilling, the fixing member 6 supports the drill bit body 3. The two main cutting edges 9 cut into the particleboard. At the same time, the plurality of cutting members 8 increase the cutting force. The two chip discharge groove bodies 7 discharge the cut chips. Compared with the related technology, a veneered particleboard alloy drill bit with double spiral chip discharge grooves provided by the present utility model has the following beneficial effects: Thus, it achieves the effect of reducing the wear that easily occurs on the cutting edges of the cutting body during long-term use and improving the drilling efficiency.

[0031] Embodiment 2:

[0032] Please refer to FIGS. 1-4 in combination.

[0033] The outer surface of the connecting sleeve 4 is inserted and connected with the shank body 1. A fixing bolt 5 is threadedly connected to the outer surface of the connecting sleeve 4. The connecting sleeve 4 is fixedly connected to the shank body 1 through the fixing bolt 5.

[0034] Specifically, by inserting and connecting the outer surface of the connecting sleeve 4 with the shank body 1, and then, when the diameter of the fixing member 6 does not meet the opening size requirement, separating the connecting sleeve 4 from the shank body 1 and replacing the connecting sleeve 4 that meets the requirements, and fixedly connecting the connecting sleeve 4 to the shank body 1 through the fixing bolt 5, the effect of facilitating use and improving applicability is achieved.

[0035] In the embodiment: The diameter of the connecting sleeve 4 is smaller than the diameter of the fixing member 6, and the fixing bolt 5 and the connecting sleeve 4 are arranged at an angle of 90 degrees.

[0036] Specifically, because the diameter of the connecting sleeve 4 is smaller than the diameter of the fixing member 6, damage to the connecting sleeve 4 during cutting is avoided. Moreover, the fixing bolt 5 and the connecting sleeve 4 are arranged at an angle of 90 degrees, so the fixed installation is more firm and it is convenient for replacement.

[0037] Working principle: Since the outer surface of the connecting sleeve 4 is inserted and connected with the shank body 1, a fixing bolt 5 is threadedly connected to the outer surface of the connecting sleeve 4. At the same time, the connecting sleeve 4 is fixedly connected to the shank body 1 through the fixing bolt 5. Insert the outer surface of the connecting sleeve 4 and the shank body 1, and then, when the diameter of the fixing member 6 does not meet the opening size requirement, separate the connecting sleeve 4 from the shank body 1 and replace the connecting sleeve 4 that meets the requirements. Compared with the related technology, a veneered particleboard alloy drill bit with double spiral chip discharge grooves provided by the present utility model has the following beneficial effects: Thus, the effect of facilitating use and improving applicability is achieved.
