What are the differences between a metal bit and a wood bit in terms of their durability and effectiveness for drilling various materials?

Metal bits are generally more durable than wood bits and are better suited for drilling harder materials such as metal or concrete. Wood bits are typically less durable but are more effective for drilling softer materials like wood or plastic. Metal bits have a sharper cutting edge and can withstand higher speeds and pressures, while wood bits are designed to create clean holes in softer materials without splintering.
