Metal Oil

Should I put oil on the metal I am going to drill through?

I am going to drill through a thinnish piece of metal and I was wondering if putting oil on it will prevent the drill bit from warping or overheating? or at least prevent it happening so quickly?

If the metal is thin you don't need the oil. Make sure to use a center punch first before drilling. This will keep your drill bit from sliding. If you don't have a center punch use a nail to make a starter mark.

For drilling through heavier pieces of metal I would recommend using oil. The oil cuts down on friction and helps to produce less heat, and prevents the bit from becoming dull to quick.
