When drilling metal, cutting oil should be used to lubricate it. This is because metal can be very difficult to drill through without proper lubrication. The oil will help to keep the drill bit from overheating and will also make the drill bit last longer.
What is cutting oil?
Cutting oil is a lubricant used during machining operations such as grinding, drilling, and turning. The oil is applied to the cutting tool to cool and lubricate the tool and workpiece, reducing friction and heat buildup. Cutting oils also prevent chips from welding to the tool and workpiece, making chips easier to remove. Cutting oils typically contain sulfur, chlorine, and other chemicals that can be harmful to the environment and human health.
How often should I reapply cutting oil?
While there is no one answer to this question as it will depend on the specific cutting oil being used as well as the application, in general, it is typically recommended to reapply cutting oil every few hours. This will help to ensure that the cutting oil is effective and can help to prolong the life of your tools.
Frequently Asked Questions
What is cut oil used for in drilling?
Cutting oil is used in drilling as a lube and coolant. It helps to prevent tip welding, pitting, and metal seizures, and improves machine finish.
Do you need to lube when cutting metal?
Yes, you will need to use a metal lube when cutting metal to prevent heat build up and wear on the bit.
What kind of oil should I use for metal cutting?
Use a high-quality cutting oil or fluid. Some recommended oils include TEMPer™ from Milwaukee Tool, GearWrench Cutting Oils, and their own Max Life® line of metal cutting fluids.
Why do you Lube a drill bit?
A drill bit that is properly lubed will cut more efficiently, resulting in a longer life for the bit and less chance of chafe or snagging. Appropriate use of cutting oils can significantly extend the life of a drill bit.
What is the best cutting oil for drilling metal?
The best cutting oil for drilling metal is Tap Magic Cutting Fluid.
