What are the key differences between wood drill bits and metal drill bits, and how do these differences impact their performance and suitability for various drilling tasks?

Wood drill bits are designed with a sharp point and flutes to remove wood chips efficiently, while metal drill bits have a more gradual point and are made of harder materials to withstand the hardness of metal. These differences impact their performance as wood drill bits are better for softer materials like wood, while metal drill bits are more suitable for drilling through metal and other hard materials.
