Technical Field
[0001] The utility model relates to the technical field of wood material processing, in particular to a hard alloy forming drill and milling cutter for processing wood composite materials. Background Art
[0002] A milling cutter is a rotary tool with one or more teeth used for milling. During operation, each tooth cuts off the excess of the workpiece in sequence and intermittently. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. Existing drilling and milling cutters are used for processing and planing wood materials.
[0003] However, the prior art is weak in smoothing the planed surface when planing wood materials. In actual use, some drill and milling cutter heads are unable to smoothly process the planed surface of wood materials when planing or drilling holes on the surface of wood materials, and after planing and drilling are completed, there will be a large number of burrs on the surface, which requires secondary processing by workers, resulting in limitations in the smooth processing of wood materials by the prior art.
[0004] Moreover, the prior art has a weak function of fastening the drill and milling cutter during rotation. In actual use, if the drill and milling cutter is not fastened during rotation, the drill and milling cutter may be separated from the mounting body under high-speed rotation. In addition, the installation process is cumbersome and time-consuming, resulting in low work efficiency. Utility Model Content
