[feature] Milling cutters deliver precise and efficient cutting results. The "extra long" design is ideal for machining deep grooves. The spiral milling cutter bit is made of high-quality carbide for high durability and excellent cutting performance. Carbide has better durability and heat resistance. Milling cutters have two sharp cutting edges. The twin-helix design of the helical mill bit enables efficient chip evacuation and reduces vibration during operation, resulting in smoother, more precise cuts. Spiral milling cutters for wood carving produce clean, professional results. Spiral milling cutters are suitable for processing materials such as plywood, MDF, particleboard, and soft and hardwoods. Router bits can be used on CNC machine tools, handheld routers, router tables and other machinery, integrating seamlessly into existingsetups.
