What are the key differences between using a metal drill bit versus a wood drill bit for various drilling applications?

Metal drill bits are designed to cut through hard materials like metal, while wood drill bits are better suited for softer materials like wood. Metal drill bits are typically made of stronger materials like cobalt or titanium, while wood drill bits are usually made of high-speed steel. Additionally, metal drill bits have a sharper point angle to penetrate tough surfaces, while wood drill bits have a more gradual point angle to prevent splintering.
