Which material is commonly used for manufacturing drill bits?

High Carbon Steel (HCS) and High Speed Steel (HSS) are materials specifically designed to withstand the wear and heat generated during the drilling process. These steels offer high hardness, exceptional toughness, and the ability to maintain a sharp edge, making them particularly suitable for cutting tools like drill bits.

High Carbon Steel provides the hardness necessary for drilling through various materials, while High Speed Steel is engineered to retain its hardness even when subjected to high temperatures during operation. This combination of properties ensures longer tool life and efficient drilling performance, making HCS and HSS the preferred choices for manufacturing drill bits in various applications.

In contrast, aluminum is generally too soft for use in drill bits; wood is not suited because it cannot withstand the drilling process; and plastic lacks the necessary strength and durability to function effectively as a cutting tool.
