Mark, label, and trace metal workpieces directly inside CNC machine tools with industrial-grade Markers (CNC workpiece marking tools / spring-loaded scribing tools). Designed to mount in standard toolholders or collet chucks, these precision marking devices utilize a wear-resistant carbide point driven by internal spring force or pressure to scribe clear, permanent identification marks, batch numbers, alignment lines, and barcodes on raw or finished metal components. Ideal for automated production processes, they eliminate manual hand-scribing, ensuring rapid, highly repeatable, and burr-free part labeling directly within the machining setup.
