Further, the sawtooth is made up of sawtooth matrix, hard alloy particle layer and dry copper bisque, the sawtooth base
Body, hard alloy particle layer and dry copper bisque are fixedly connected sequentially and formed, the hard alloy particle of the hard alloy particle layer
A diameter of 2-8mm.
Further, the thickness of the sawtooth matrix is 6-9mm, and the thickness of the hard alloy particle layer is 4-8mm, institute
The thickness for stating dry copper bisque is 2-4mm.
Further, the angle of the tangent line on the sawtooth and blade body of the arc shaped blade structure is 15-25 °.
Further, a diameter of 4-7mm of the chip area, the chip area is consistent with the number of sawtooth, described to dissipate
A diameter of 6-14mm of hot hole.
The beneficial effects of the utility model are as follows：
(1) sawtooth of the present utility model by sawtooth matrix, hard alloy particle layer and dry copper bisque be fixedly connected sequentially and
Into effectively raising the hardness of sawtooth, extend the service life of sawtooth.
