As preferably, between the front edge of front cutter face and chisel edge, there is approaching side, approaching side and rear cutter face tilt, and chisel edge is by approaching side and crossing formation of rear cutter face.The existence of this approaching side makes the initial position of front cutter face have suitable thickness, the initial angle of inclination of front cutter face hour also can ensure the intensity of firmer chisel cutter, and the existence of this approaching side is shortened the cycle that chisel edge is worn, can increase the service life, in reconditioning, only need reconditioning approaching side, improve grinding efficiency.
As preferably, the angle of inclination of approaching side is greater than the angle of inclination of position, end in face of front cutter.
As preferably, the length of approaching side is 0.2-2mm, and the angle of inclination of approaching side is 45 ° to the maximum.The length of approaching side and angle of inclination can change, and especially, for the different instructions for uses of firmer chisel cutter, the length of approaching side and angle of inclination can independent design.
A kind of preferred scheme: front cutter face is that many inclined-planes combine, and each inclined-plane is plane.Cutter face before multiple inclined-planes composition, processes fairly simple.
As preferably, the angle of inclination on each inclined-plane of front cutter face to increase progressively angle all identical.
As preferably, the angle that increases progressively at the angle of inclination on each inclined-plane of front cutter face increases gradually.
The preferred scheme of the second: front cutter face is cancave cambered surface structure, the thickness at front cutter face place increases to chisel grip gradually from chisel edge.Front cutter face is cancave cambered surface, and incision effect is more desirable, and the intensity at front cutter face rear portion is more reasonable, and this cancave cambered surface can also play guiding function to wood chip simultaneously.
The beneficial effects of the utility model are: the angle of inclination of front cutter face is not unified, but change, and this angle of inclination increases gradually, the angle of inclination of the front cutter face at close like this chisel edge place is little, and in the time of initial vertical incision Wood surface, the resistance being subject to is little, can increase so the once degree of depth of incision, need not return to incision again follow-up in picking out wood chip, raise the efficiency, also can not damage by the other side's bore ends timber; The angle of inclination of front cutter face increases gradually, be also consider penetraction depth increase after the intensity of firmer chisel cutter while picking out wood chip, place firmer chisel cutter broken end while picking out wood chip.
