1, ordinary knife alloy knife: high-performance alloy material, double-edge design, good sharpness, high cost performance, easy to re-grind by hand. Disadvantages: The angle of this knife is not standard (there is a big angle at the tip), so it is not suitable for relief. Generally used for carving bluestone and marble!
2. Standard angle alloy knife: made of high-performance alloy, double-edged design, standard angle, lettering and fine relief. Generally used for carving bluestone and marble! Can be customized and polished into a flat-bottomed sharp knife.
3. Melting drill grinding knife: The melting drill grinding knife adopts military high-tech "melting drill technology"! It has the characteristics of good sharpness, high carving efficiency, no deformation of the cutter head and high carving accuracy! Therefore, when carving marble, bluestone, sandstone and other materials, it is often used as the first choice tool for efficient relief and a sharp weapon for carving Chinese characters.
4. Integral alloy triangular knife: The integral alloy triangular knife is made of ultra-fine wear-resistant alloy. The wear resistance is much higher than other triangular knives on the market. Angle standard, good lettering effect! Customers of universal cutter grinder can use this kind of knife. No universal cutter grinder, not recommended!
PCD Polycrystalline Diamond Blade: Imported Polycrystalline Diamond Blade, the quality is far from cheap domestic blade comparable! Using vacuum welding technology, the blade will not be damaged or fall off; Microgrinding technology optimizes the sharpness and strength of the blade. Generally used to carve granite fine print. Good hardness, long service life and good carving effect. Pay attention to cutting flexibly when using, and don't use too much force when cutting!
6. Sintered diamond grinding head cutter: Sintered diamond grinding head is generally used for milling granite bottom. Because the cutter head is made of multi-layer diamond sintered, the service life is very long! The disadvantage is that the sharpness is not high and the cutter head will be deformed. Therefore, for carving marble, bluestone and other materials, in order to obtain higher output and carving effect, sintering knives are not recommended. When making granite and other difficult-to-process stones, in order to avoid excessive tool cost, you can choose sintering grinding head knife!
7. Diamond four-edged knife: generally used for carving granite small characters or lines. The advantage is long service life, but the disadvantage is relatively poor sharpness and shallow carving depth!
