Granite has a hard texture and high density, and ordinary tungsten steel knives are prone to wear. Granite carving knives are generally made of solid hard alloy materials. Cutting tools are divided into flat bottomed pointed knives, ball end knives, and tapered milling cutters. The cutting edge is strengthened to resist impact and wear, and is less prone to tooth breakage.

    This type of cutting tool has a sharp edge and can cut stone at high speed, carving large character contours, deep grooves, and relief patterns. A tapered flat bottomed knife is used to follow contour lines and cut edges neatly and cleanly; The ball head knife is used for curved relief, with smooth and natural transitions in the patterns. The blade has high hardness and can be operated continuously for a long time, reducing frequent tool changes.

    Stone has high dust and strong cutting resistance, so the cutting edge of the tool has been thickened and reinforced. Compared to woodworking knives, granite carving knives have thicker and more rigid blade bodies. It is widely used in stone tablet engraving, stone relief, and landscape stone processing. Reasonably controlling the depth and speed of the cutting tool can ensure carving accuracy and effectively extend the service life of the tool, making it a specialized tool for stone CNC machining.
