The Datou Roland engraving knife relies on three core design principles: stepped Datou limit structure, conical cutting edge, and overall rigidity reinforcement, and is suitable for high-speed reciprocating cutting operations of engraving machines. The tail of the cutting tool is equipped with a thickened limit head, forming a stepped positioning structure. After being installed in the tool holder, it can be precisely clamped to prevent the tool from moving up and down, axial displacement, and solve the problem of uneven positioning and depth of ordinary small knives, ensuring a constant cutting depth throughout the entire process.
The blade adopts a thickened integrated handle design, which enhances the overall bending rigidity. When the engraving machine rotates at high angles and speeds, it effectively suppresses the shaking of the blade head and avoids deformation during curved and small character cutting. The front end adopts a high-precision conical sharp blade structure, matched with 30 °/45 °/60 ° blade angles according to different cutting materials. Using the principle of wedge-shaped extrusion, it can easily cut advertising film, reflective film, adhesive and other materials, and the incision is smooth without drawing burrs.
At the same time, the large head structure fits the contact surface of the tool holder more evenly, reducing tool wear and extending service life. It is perfectly compatible with Roland and domestic general-purpose engraving machines, balancing cutting accuracy and operational stability.
