Deep round bottom cutter is a commonly used type of woodworking milling cutter. The core design principle is to use the overall circular arc structure of the cutting head to form a deep groove at the bottom of the circular arc in one cutting, and to adapt to special processes such as wire grooves, decorative grooves, and invisible handle grooves. The cutting head adopts a standard circular arc surface design, which precisely matches the required groove bottom curvature of the workpiece, replacing the secondary bottom repair process of flat bottom milling cutters, greatly improving machining accuracy and efficiency.

    The cutting tool adopts a deep blade lengthening structure, optimizing the blade length ratio for deep groove machining, balancing cutting depth and tool body rigidity, and avoiding vibration and edge collapse during deep cutting. The cutting edge adopts a symmetrical and evenly distributed arrangement, which ensures uniform cutting force and effectively reduces machining vibration. At the same time, the blade body is reserved with a wide spiral chip discharge groove, which can quickly export wood chips during the deep cutting process, avoiding chip accumulation, burning of the workpiece, and tool jamming. The front and back corners of the cutting tool have been optimized to balance sharpness and wear resistance, allowing for smooth cutting of wooden materials while reducing edge wear, ensuring consistency in batch processing.
