Hey guys I shot this video to show you my trick to drill stainless steel. I’m a Field metal worker and these are my tips for drilling with limited supplies with hand tools. Of course its always easier to do a job with the Best tools and supplies but we can’t always have what we want!
#1 Center punch is a semi hardened rod with a blunt point that is used to put a dimple in the metal when hit with a hammer. With this dimple drill bit gets a positive start does’t walk.
If you don’t have a center punch sometimes I’ve used a large wood screw (nails don’t work well because they are soft.).
#2 Use a smaller drill bit than your final hole size. If your hole is larger than 3/16″ I suggest a 1/8″ pilot hole.
#3 GO SLOW, going to fast over heats the drill bit. Heat is your enemy.
#4 Lubricate (oil) or cool your drill bit often (water), I prefer water and cooling it often just because I don’t like the huge oil mess and needing to degrease the parts after drilling. This technique is good for less 12 holes, if you have more consider upgrading your tools and lubricant. TIME IS MONEY!
