The accompanying drawing explanation
The structural representation of the flat-wing driller that Fig. 1 provides for the utility model embodiment.
In figure: Reference numeral: 1, drillstock; 2, apex point; 3, the heavy sword that cuts; 4, side is cut sword; 5, inclined-plane; 6, bit-withdrawing slot; 7, bore body.
The specific embodiment
With reference to Fig. 1, the utility model embodiment is described further.
A kind of flat-wing driller, comprise drillstock 1 and drill bit, described drill bit comprises apex point 2, heavy cuts sword 3, side is cut sword 4 and bored body 7, drill bit and drillstock 1 connect as one, and it is characterized in that: apex point 2 is located at body 7 centers of boring, and apex point 2 blade tip height cut higher than heavy the blade tip height that sword 3 and side are cut sword 4, it is circular-arc that side is cut terminal knife edge on sword 4, the side that side is cut corresponding apex point 2 one sides of sword 4 forms the parallelogram face, and the heavy sword 3 that cuts cuts 4 of swords with side and is provided with inclined-plane 5, and inclined-plane 5 cuts sword 3 to side, to cut sword 4 downward-sloping by sinking.When drilling machine or rig are driving flat-wing driller and are working on workpiece, apex point 2 is in the drill bit top, tough and tensile and sharp degree by tip thrusts in workpiece, side is cut sword 4 blade tips and is cut saw at periphery, heavy cut sword 3 and cuts the rotating speed of sword 4 by drilling machine or rig with apex point 2 and side, perfectly hole drill is gone out in workpiece, make the detritus of workpiece, along with the rotation of flat-wing driller drill bit, from side, cut sword 4 and the heavy inclined-plane 5 that cuts 3 of swords spills, arrived the flat-wing driller outside.Avoided residual bits head can't get out and flat-wing driller is stuck, and damaged flat-wing driller, also avoided residual bits head to hit the blade point at a high speed because of the drilling speed of drilling machine, blade tip is damaged.Such flat-wing driller, not only improved operating efficiency the life-span of flat-wing driller, intensity improved greatly.
