About tool handle diameter
The choice of the diameter of the tool holder is mainly to choose a reasonable tool body strength to prevent the tool from breaking. Generally speaking, 8MM shank diameter is preferred for reliefs within 2 cm, and 10MM shank diameter is preferred for reliefs above 2 cm. The engraving machine has excellent performance and customers who run high-speed can choose a 12MM tool holder to meet the high-speed requirements.
About the tool tip size
In the case of meeting the requirements of engraving accuracy, try to choose a model with a larger tip. The larger the tip, the longer the life. For example, if the 6MM tool tip can meet the requirements of engraving accuracy for large-size reliefs, try not to choose a 3MM or 4MM tool tip.
About blade length
Depending on the flatness of the stone and the set carving depth, you should choose a blade length with margin to prevent accidental sharpening of the knife handle. For example, if the engraving depth is 26MM, the blade length is 30MM. If the engraving depth is 15MM, the blade length is 20MM.
