Not every material cuts like aluminum.
FR4, carbon fiber, fiberglass, G10, and other composite materials are abrasive, layered, and demanding on tooling. Standard cutters often struggle with chip evacuation, edge quality, and tool life when machining these materials.

Whether you're producing prototype circuit boards, machining carbon fiber components, corn Bits are designed specifically for these challenging applications. Their unique cutting geometry helps break chips into smaller pieces and improve evacuation during machining, making them a popular choice for PCB fabrication, carbon fiber cutting, and composite material processing.
