Differences between wood drill bits and metal drill bits

Differences between wood drill bits and metal drill bits

Wood drill bits and metal drill bits are two different types of drill bits. The main differences between them are as follows:

1. Different materials: wood drill bits are usually made of high-speed steel, while metal drill bits are usually made of carbon steel or cobalt steel.

2. Different drill bit geometries: Since wood is softer than metal, wood drill bits are designed to be larger and have a larger drill mouth angle to facilitate the discharge of wood chips. Metal drill bits have a smaller drill mouth angle to better grasp metal materials.

3. Different drilling diameters: wood drill bits are generally designed for drilling large-diameter holes or deep holes, while metal drill bits are often used for small-diameter or shallow holes.

4. Different uses: wood drill bits are mainly used for drilling wood, wood boards and plastics, while metal drill bits are used for drilling hard materials such as metal, steel, and alloys.

In short, the design and manufacturing characteristics of wood drill bits are suitable for drilling flexible materials, while metal drill bits are suitable for processing hard materials. Therefore, different types of drill bits should be selected according to needs when using them.
