16 mm Round Bottom Router Bits are specialized cutting tools used in CNC routers and hand routers for creating smooth, concave grooves, fluting, and decorative carving. With a 25mm diameter cutting edge and a rounded bottom profile, these bits are ideal for sign-making, engraving, and 3D contouring in wood, plastic, and composite materials. Made from carbide, they offer durability, precision, and a clean finish, making them essential for detailed woodworking and CNC machining projects.
