| I am in desperate need of help.
I have a stainless steel countertop (stainless steel wrapped around 1-3/4" thick MDF). I need to cut a faucet hole in it that is 1 1/4" in diameter. I have no idea how to acheive this. I know I will need to mark out a center point and the circumference. I think I will need to use a center punch to nick the center before I start drilling with a bit that is OK to use on metal.... But I know I am missing things here. Would anyone be willing to give me a step by step guide on how the heck to do it myself? Thanks for any advice you guys can give. secondcup |

| You need to use a 1 1/4" hole saw. The only trouble is that stainless is difficult to drill because it dulls bits quickly. You'll want to invest in a good quality hole saw (or several cheap ones). Use a center punch to mark your starting point and use the hole saw on a very low speed (maybe 350 rpm). Depending on the hole saw you may not be able to get through 1 3/4". So using the same size drill bit as the pilot bit of the hole saw, drill all the saw through. Then finish the hole from the underside of the counter top. |

| A hole saw with grit for the cutting edge will get through the metal in short order. Then switch to a regular toothed cutter for the MDF. |

| When cutting stainless sheet whether you use a drill bit or a hole saw, the key is to go slow. If you are using a variable speed drill, slow it down as far as it will go and use some oil for a lubricant. Just a tad of motor oil will work fine. |
