A drill bit typically has two flutes.
In a twist drill, the land serves several important functions. Primarily, it provides the cutting edge that removes material from the workpiece as the drill rotates. Additionally, the land helps guide the drill during operation, ensuring stability and precision. It also plays a role in chip removal by allowing chips to flow along the flutes, preventing clogging and overheating.
Flutes
The twist drill uses flutes that act as an Archimedean screw to lift swarf from the hole.
