3- Lubricating the drillbit reduces friction and heat buildup, which makes drilling easier and your bits last longer when drilling holes in steel that’s 1/8 in. 4- Make sure your drilling at slow speed for a small twist bit (1/16 in. to 3/16 in.), you can drill through most metals at 3,000 rpm. but when you use larger twist bits (11/16 in. to 1 in.), 350 to 1,000 rpm it's much better.
