How long should you drill stainless steel?
It is important therefore to stop drilling from time to time to allow the drill bit to cool down. We would recommend you do not drill for longer that 30 seconds without taking a break. As Allfasteners say in their article ‘ Drilling Stainless Steel the Right Way ’ drill the material on short bursts. The larger the drill bit size the faster the heat build up will be so this time should be reduced for larger drill bit sizes.

What kind of drill bits do I need for wood?
You can buy a set of cheap Chinese made bits. They are considerably less expensive. But… they will wear out faster, and possibly break easier, occasionally. But plenty of people use them if they have a limited amount of drilling. Drill bits that are labeled HSS (High Speed Steel) are “normal” drill bits, and are usually the ones used for wood. Off-brand HSS drill bits can work fine for you if you are just planning to drill into wood. Higher quality bits are more important if you are planning to do any drilling through thick metal. In that case, you would be using the bits with the golden color coating. There is a even lower grade of bit, made of carbon steel, used only for soft materials. But I find HSS bits to be all-purpose in most cases, unless you are building furniture or cabinetry, in which case you would use carbon steel bits made specifically for wood.
Why is stainless steel hard to drill?
The real problem with drilling stainless steel is the fact that it “work hardens” so quickly. Cutting too fast, or using a dull bit or an incorrect feed rate/drilling pressure will cause the stainless to work harden quickly, and end up burning up your bit. Using a coolant while drilling, supporting the work properly, and using a very sharp bit will allow you to drill the metal in most cases without problems.
What is a HSS drill bit?
Drill bits that are labeled HSS (High Speed Steel) are “normal” drill bits, and are usually the ones used for wood. Off-brand HSS drill bits can work fine for you if you are just planning to drill into wood. Higher quality bits are more important if you are planning to do any drilling through thick metal.
How to drill a hole in steel?
A high speed steel drill bit should work, depending on size. If it’s over 1/2″ diameter, use a pilot drill before the finish size, with lots of coolant. You’ll run it a bit slower than you would in mild steel, with about the same feed rate. Some holes I would use several pilot drills of increasing size to keep the chip load on both cutting edges below 1/4″ or so. Frequent pecking is usually a good idea, both to break the chip and cool the tip.
What is a rotaroach cutter made of?
Your Rotabroach cutter is made of M2 high speed tool steel. That’s not going to be effective with most alloys of stainless stock and is not recommended for hole depths over 1/4″ in mild steel. What you need is a 4 flute solid carbide end mill. Your best bet is to use this with an R8 collet on a milling machine. Someone with a Bridgeport type knee mill or any of the Chinese knock-offs would not be asking this question, so assuming you only have a drill press or hand drill. Don’t worry - if your slot is a half inch wide or less, you can chuck up the end mill. Just don’t give it a lot of lateral
What is thin sheet stainless used for?
Thin sheet stainless is used for trim, flashing, door kick plates, and other purposes and is almost always fastened with a mechanical fastener that requires drilling or punching for screws or rivets, Most of these only require a 1/8 inch hole that is fairly easy to drill. For larger holes, use a “stepped” drilling process drilling a pilot hole, then larger and larger holes until you reach your desired size. Support the work while drilling, and prevent the metal from getting too hot during the drilling process.
What is high speed steel?
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material.
How to drill stainless steel?
How can you drill stainless steel? Drilling stainless steel needs to be done with sharp bits, low RPM, higher cutting pressure (feed), and lots of lube/coolant. High RPM will lead to immediate burned-out drill bits.

How to center a hole under a drill bit?
Unclamp the workpiece and apply gentle pressure with the non-rotating drill bit to center the hole under the drill.
How to lubricate a drill bit?
One of the simplest ways to lubricate the drill bit is to hit it with some WD-40 as you cut. Pull the drill bit out of the hole, spray some oil on the bit, drill for a few more seconds, rinse and repeat. The down side to using WD-40 is that it’s an extremely light oil and it can get pretty messy.
What RPM to run a drill?
The RPM to run the drill at will depend on the size of the drill bit. The larger the drill, the slower you need to run it.
Why is a drill press more stable?
On a drill press, the process is more stable since the setup is more rigid and the bit is more accurately align. Depending on the torque of your machine, you can actually drill some pretty large holes.
