To select an appropriate drill bit, one must first determine the material to be drilled (such as wood, metal, masonry, etc.), as well as the required hole diameter and depth. Match the diameter of the drill bit with the screw or anchor you are using, or adapt it to the size of the required hole. Additionally, consider the type of drill bit (e.g., twist drill bits, flat - head drill bits, spade drill bits) based on the specific application and material.
Wood:
The twist drill is widely used, but the flat drill is suitable for drilling clean holes in wood. The chisel-shaped drill is suitable for larger holes. If you want to drill very clean holes (especially in finished woodworking products), you can consider using a Fosterner drill.
Metal:
For metals, high-speed steel (HSS) or cobalt drill bits are used because they can withstand the heat generated during drilling.
Bricks and Stones:
Bricks and stones drill bits are specifically designed for drilling into bricks, concrete and stones. Diamond-tipped drill bits are used for hard materials such as tiles.
Plastics:
Point-shaped drill bits can be used for plastics, but be aware of the characteristic that this material is prone to melting or cracking, and adjust the drilling speed accordingly.
