Hold the drill perpendicular to the bracket, and then place the tip of the drill bit into the mark or depression you made. Pull the trigger of the power drill and let the bit gain rotational speed as it moves around the mark. Stainless steel is a hard metal, unlike aluminum, iron, and copper. 118 and 135 degree-bits are most appropriate. They are of high precision and their cutting points bite into metal without slipping. Besides, new drill bits in this class cut well into metal than any other bits. Split point bits and twist drill bits are great for working on steel.

Used a Milwaukee dozer but 1 3/8 inches Stainless steel can be penetrated by a handheld drill with a cobalt or high-speed steel bit. Care must be taken to avoid overheating. Accidental overheating can cause damage and discoloration of the metal. It increases the risk that the steel will 'work harden', becoming more difficult to drill through. Use lubrication or water to avoid this. Drilling holes even in exceptionally hard stainless is fairly easy, even if you have comparatively simple, low-tech tools. The key is keeping the production of friction-generated heat to a minimum, either with cooling pastes and liquids or—believe it or not—plain ol' water. Here's how. Hold the drill perpendicular to the piece of steel so the tip is in the divot. Find the divot you created on the steel and place the drill bit in it. Make sure you hold your drill straight so you don't make a crooked hole in the steel. 3 Drill slowly and apply firm downward pressure.
