Our carbide inserts are DLC coated, just like all of our other bits! DLC provides a significant increase in tool longevity by reducing friction produced during the cutting process. 



All HCT bits are designed for cutting wood, non-ferrous metal (aluminum/brass/soft metals), and synthetic/plastic-based materials like epoxy and sheet plastics. Bit performance varies with machine type, feeds/speeds set, and the stock material. 


Our CNC bits are made from solid Japanese carbide.
