R0.5*2*4*50*2T
The cutting edge of the ball head knife with tungsten steel and aluminum is circular, forming a half sphere in the engraving process, and the engraving process is uniform and the cutting is smooth. Therefore, it is particularly suitable for surface engraving, and is often used for surface semi-fine engraving and surface fine engraving. Ball knives are not suitable for milling surfaces. High temperature heat dissipation and chip removal.
