For many years I hated drilling stainless steel. Its hard, it requires expensive cobalt or carbide bits and it takes a long time to drill. In other words, I had many good reasons for feeling this way. However, as it turns out, all of them were based on incorrect information. First and foremost best s420n steel drilling
No Drill Hard Plate, Anti Drill Plate, 440C Stainless Steel Pro Good for hand drills and most drilling applications Con Has limits with hardened steel. Carbide Tipped Will drill almost any steel, Hard, Stainless or Mild. Pro Drills all steel Con- Blunt tip requires extreme pressure to produce cuttings. Drill bit is hard to start on all steels. Diamond Coated Drill Bit Cuts on most steels(Not Hard Plate) just not for long.
Drilling through metal is a lot harder than drilling through wood, and you'll need a tougher drill bit. Take a look at the drill bit you've got now -- it probably tapers to a point, which is the sign that its not right for steel. Go to a hardware or home improvement store for a cobalt bit that is designed specifically for drilling through steel.
High speeds cause too much friction and high heat levels. Slow and steady drilling speed is best when drilling metal. Step Seven: If you notice any smoke, youre drilling too fast or not using enough oil to lubricate the drilling process. STOP and allow the drill bit to cool. You can squirt some oil on the bit to cool it faster.
Drilling steel or metal is a quick way to dull your drill bits if you do it the wrong way. This AsktheBuilder.com video shows you how to drill holes using the correct bits and oil to drill through best s420n steel drilling

When drilling through-holes a backing plate should be used to help avoid drill breakages as the drill comes out of the blind side of the hole. Drill geometry Although standard High Speed Steel (HSS) drills are suitable for drilling stainless steel, they should preferably be shorter to reduce deflection and breakages in use.
Which Drill Point Angle Should I be Using? The selection of an appropriate drill point angle for your bit should be informed by questions about your application. Yesa hole is a hole is a holebut what is the purpose of the hole, what type of metal are you cutting into, and what are the specifications for the finished hole?
If you are using a drill bit suitable for steel, then yes, providing the drill itself has enough power, this will be fine. Even a low power drill can do this successfully, you will just need to take it slow in order to avoid getting the bit stuck. A higher power drill will manage without much of a problem.
