The term anchor bit refers to the specific part of a ship's anchor chain that connects the anchor to the ship. It is the point where the force of the wind, tide, or current is transmitted from the anchor to the vessel, making it a crucial element in ensuring the ship's stability. Historically, anchors were made from stone or wood, but with the advent of metal fabrication, the anchor bit evolved into a robust, durable structure designed to withstand immense pressure.

Material selection for integral drill rods is crucial to their performance and longevity. Typically made from high-speed steel (HSS) or carbide, these rods are heat-treated to withstand the stresses of high-speed drilling and the friction generated during thread formation. HSS offers a good balance of toughness and hardness, while carbide provides superior durability and cutting efficiency, making it ideal for drilling through harder materials.
