Carbon steel drill bits come in three primary types low-carbon, medium-carbon, and high-carbon. Low-carbon steel bits, with a carbon content typically below 0.35%, are more flexible but less durable, making them suitable for softer materials like wood. Medium-carbon bits, with a carbon content between 0.35% and 0.60%, strike a balance between strength and toughness, while high-carbon bits, with a carbon content above 0.60%, offer superior hardness and wear resistance, ideal for drilling into harder materials like metal.

The thread button bit, also known as a tap drill bit or a threading bit, is an essential component in the process of thread cutting. Its design incorporates a button-shaped projection at its end, which not only aids in the initial piercing of the material but also contributes to the accuracy and stability during the threading operation. The 'button' serves as a cutting edge, shearing off material as it rotates, gradually forming the required thread pattern.
