A stainless steel kitchen sink is one of the preferred sinks of today's homeowner because of its relatively low price, because its ease to clean, and because it resists corrosion and stains. But because this sink is steel, if you wish to install an additional fixture such as a spray hose that requires an additional hole, you'll find that this sink presents a challenge when it comes to drilling that hole. But with the right tools and instructions you can drill such a hole.

Step 1 – Determine Where to Drill Your Hole

Before beginning to drill your hole in the sink, you'll need to know where to drill it. There are two issues to take into account: a) potential damage to fixtures under the sink, b) distance from needed fixtures such as a water pipes or drain pipes. To avoid drilling your hole in the wrong place, survey the underside of the sink. If advisable, measure from needed fixtures to the place on your sink where you'll want to drill your hole. Place a small piece of making tape on the place where you'll make your hole on the top surface. Then make a mark on the masking tape where your hole will be made.

Step 2 – Make an Indentation

To keep your drill bit from skipping across the surface of your sink when the drill is spinning, create a small indentation. Hold the point of a nail set, or large nail, on the mark you made on your sink. Strike the top of the nail set with a hammer hard enough that it will make an indentation. You may need to strike it more than once.

Step 3 – Lubricate Your Drill Bit

To prevent your drill bit losing its temper or its sharp edge, apply a drop of lubricating oil on the point of the bit. As your bit turns, keep it lubricated by applying more oil. If your bit begins smoking, this means it is becoming too hot and may lose its temper.

Step 4 – Wear Protective Eyewear

Before starting to drill, be sure you are wearing goggles or other protective eyewear. Tiny bits of steel will commonly fly from the spinning bit and can damage your eyes if struck by one of these shards.

Step 5 – Begin Drilling

With the 1/4 inch drill bit in your drill, place it the point of your bit on the mark you made on your masking tape that is stuck to your sink surface. Begin to drill at a low speed, keeping your drill bit in a vertical position. The slower, the better. When you've determined that your bit has begun to penetrate the sink surface, stop the drilling. Replace the 1/4 inch bit with the 1/2 inch bit, apply oil to the bit, and continue drilling until you've bored through the sink surface. Remove the drill bit and insert a metal file into the hole. File the hole sides to remove any sharp or uneven metal edges in the hole.
