What materials are typically used for CNC cutting tools?

High-speed steel and carbide are commonly used materials for CNC cutting tools due to their exceptional hardness, durability, and heat resistance. High-speed steel (HSS) is capable of retaining its hardness at high temperatures, which is beneficial for fast cutting operations. It is often used for drilling and milling applications where strength and wear resistance are critical.

Carbide tools, particularly tungsten carbide, offer even greater hardness and can withstand higher temperatures than high-speed steel. This makes them ideal for machining tougher materials and for longer tool life, as they retain their cutting edge even under demanding conditions. Their ability to cut with precision and speed makes them a preferred choice in various CNC machining applications.

Choosing the right material for CNC cutting tools is essential, as it affects the efficiency, precision, and quality of the machining process. Other materials, such as aluminum and brass, are more likely to be the workpieces rather than the cutting tools themselves, while plastic, rubber, wood, and composite materials may not have the necessary hardness for effective cutting tool applications.
