What are the differences between metal and wood drill bits, and how do they affect the drilling process?

Metal drill bits are typically made of high-speed steel or cobalt, while wood drill bits are usually made of carbon steel or high-speed steel with a brad point tip. Metal drill bits are designed to withstand the high heat generated when drilling through metal, while wood drill bits have a sharp point for precision drilling in wood. The differences in material and design affect the drilling process by determining the speed, accuracy, and efficiency of drilling through different materials.
