The Proper Speed and Pressure to Use: While drilling, you need to use the proper speed and pressure on the tool. If you are drilling into something hard, you will want a slower speed and pressure. This causes the drill bit to cut through better. However, if you are drilling into a softer material then there is no need to go slow, and less pressure can be applied without ruining the material.

It will be best if your drill bit does not have a dull element, otherwise your drill bit will face some issue while cutting through any material. It can damage not only the material but also the drill as well. Make sure the drill bits in use are sharp enough.
