The Role of Lubrication in the Drilling Process

Drill bits create holes by rotating at a very high speed. This generates a lot of heat that might end up affecting the functionality of the drill bit or the drill itself. You need to stem this heat before it becomes dangerous by use of water or a lubricant. Proper lubrication helps extend the life of the drill bit while making sure the bit doesn’t get damaged as you work.

Different Materials Have Different Lubrication Needs

One of the most sensitive materials to heat is glass and tile. While drilling through these materials, you need to make sure the drill doesn’t get warm at all. Make use of lubricant when drilling through these materials. Concrete drilling also needs lubrication, but you can use a continuous stream of water instead of oil.

Metal drilling needs you to have the right coolant nearby. You can swap the coolant with motor oil because both work properly for metal. You can also use cutting fluid to cool the tip. When drilling soft abrasive metals such as aluminum, stainless steel and copper, use oil as well, which helps remove chips that can wedge between the drill bit and the stock.

Additionally, the type of drill dictates how much lubricant to use. If one was fortunate enough to follow correct purchase tips and read expert reviews, the drill bit won’t need so much lubricant, just the occasional pulling out from the hole.

Techniques of Lubrication

You can use a water hose that supplies water continuously onto the top of the hole as you drill. Another option is to use a small bottle with a hole in the cap. Make sure the hole is large enough to allow water to flow into the hole without the need to press the bottle.

Another method is to place water in a container and dip the drill bit into the water after every few minutes. Make sure the water level is high enough to cover the entire length of the drill bit.

Choosing the Best Lubricant

Just because some lubricants have been recommended doesn’t mean they will work for every situation. You have to find a way to get the best lubricant for each job. Make sure you understand the specifications of the job and the recommended drill bit speed you are going to use to execute the process. Once you understand this, you can make the best decision.

Final Thought

You need to find the best lubricant that is ideal for the material you are drilling through. Water is general purpose, but you can use special kinds of coolant or lubricant for specific materials.
