How to Drill Holes Into Stainless Steel

Right tools and techniques. This guide will walk you through all the steps necessary to drill into stainless steel successfully. With a few essential tools and techniques, you’ll be able to get the job done in no time!

First Things First – Select Your Drill Bit

When drilling into stainless steel, the key to success is selecting the right drill bit for the job. Several types of drill bits are available on the market, but for most applications in stainless steel, you’ll want to use a cobalt-tipped drill bit. Cobalt-tipped bits are designed explicitly for hardened metals such as stainless steel and will give you better results than standard twist or masonry bits. It’s also important that your bit be sharp; if it isn’t, it may struggle to penetrate the hard surface of the metal.

Mark Your Spot

Once you have your drill bit ready to go, it’s essential that you precisely mark where your hole should go. You can do this with a pencil or marker, but it’s best to use a center punch so that your bit will stay centred when drilling into the metal. This is especially important when drilling larger holes, as off-centre drills can cause unnecessary wear and tear on both your bit and your material.

Drill Away

Now that everything is set up correctly, it’s time to begin drilling! Start by setting your drill speed at a moderate level – too slow, and you won’t penetrate the metal; too fast, and you’ll overheat your bit. As you begin drilling, keep an eye out for any sparks coming from the hole; if none are present after a few seconds of drilling, increase your speed until sparks appear again. Drilling slowly at first will help prevent wear on both your material and your bit, so don’t rush things! Once all is said and done, clean up any dust or debris created by drilling before moving on to other tasks.


With these tips in mind, anyone should be able to drill holes in stainless steel with minimal effort successfully! Remember—it’s always best to start slowly so as not to put too much wear on your material or tools; take things one step at a time, and don’t rush! With some patience and practice, you’ll soon be an expert at drilling into stainless steel!
