The standard four-sided pyramid tip is precision-machined in one piece with standardized angles and minimal concentricity deviation, ensuring high-speed engraving without deviation and straight, crisp lines. The high-density diamond is securely brazed and locked, preventing sand loss and dulling, offering long-lasting wear resistance and significantly reducing frequent tool changes and downtime. The blade exhibits moderate rigidity, with evenly distributed pressure for shallow engraving, making it ideal for various hard stone surface engraving applications. It boasts exceptional cost performance, though its only limitation is unsuitability for deep, heavy-duty relief work, specializing in flat marking operations.
