If you're a handyman, any old oil you have laying around is better than none: motor oil, machine oil, ATF, WD-40, whatever. Don't use something super flammable with a low flash temperature.

What kind of oil do you use on metal?
With metal oil, a drying oil, such as boiled linseed or tung oil, is a better choice than raw linseed oil or mineral oil. It's also a good idea to thin the oil before applying it and to heat the metal to improve penetrability.
How do you drill through hardened stainless steel?
To drill through stainless steel, you need an HSS (High-Speed Steel) drill bit. HSS drill bits have sharp edges that can cut into the tough metal. To cut into hardened stainless steel, you will require a drill bit with a large point angle of at least 130 degrees.Oct 8, 2020
What oil protects metal from rust?
Iron starts to rust when the metal surface is exposed. For example, oxygen in combination with water. You can prevent rust easily by coating the metal object with an oily shield using a cloth that has been treated or trunk with linseed oil.
What kind of drill bit will cut hardened steel?
cobalt bit
Do you need a special bit to drill through stainless steel?
Stainless steel is a very hard material and therefore difficult to cut. Therefore, the tool steel of the twist drill should be made of HSSE-Co 5 (5% cobalt content), HSSE-Co 8 (8% cobalt content) or solid carbide. So since stainlesssteel is a hard material, you need a twist drill type H.
What can be used as lubricant for drilling?
I use just WD 40 in aluminum or other softer metals, IF I am drillingsteel I used just a drop or two of the mixture I use on the lathe and milling machine which if Vactra way oil mixed with some STP, about 5 to one. You could also use thread cutting oil if you have it.
What drill is best for stainless steel?
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainlesssteel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.Aug 4, 2021
What liquid is used for drilling metal?
It is called “Hydrated Oil”. Essentially, oil is needed for lubrication of the cut, but oil is a poor coolant, and wears out quickly if used to cool the work piece as it is cut.
Can you use vegetable oil for drilling metal?
They are used to provide lubrication and cooling effects between cutting tool and work piece and cutting tool and chip during machining operation. In the present work, different non-edible vegetable oils are used as cutting fluid during drilling of Mild steel work piece.
What oil do you use for tapping?
Generally, for best tap performance, straight cutting oil should be used. For non-ferrous and non-metallic materials, a coolant or a cutting fluid (light oil or soluble oil) is recommended.
