carbide v-scoring blade
- High hardness, good wear resistance, sharp edge
- High surface finish and no burrs for cutting PCB
- Long service life, increase production efficiency
- Premium wolfram carbide and cobalt powder as raw materials
- Regular sizes in stock, quick delivery
Carbide v-scoring blade is mainly used for v-cutting machine to cut off v-shaped grooves on printed circuit boards, so as to separate a single circuit board from assembled ones.
Solid carbide v-cutting blade is with high wear resistance, sharp edge, and good surface finish. It can cut 50HRC hard material. The service life is 20~150times longer than that of tool steel. It can greatly reduce the time of tool changing, and enhance production efficiency. PCB depaneling with a tungsten carbide v-cut blade results in smoother, burr-free edges, significantly improving PCB quality.
