How to Drill a Hole in Hardened Steel
- 1). Place the steel on top of a piece of wood so that when you drill through it you don't dull the bit on concrete or another hard surface.
- 2). Place a small amount of oil on the area of the steel where you're going to drill your hole. The oil will help lubricate the drill and keep the temperature low.
- 3). Drill very slowly into the steel so you do not damage the bit.
