How to drill through metal?

Do you want to know how to drill through metal? You can make use of this article to find out all about this process. First of all, we will discuss the tools and equipment required for performing this drill. Then, we will be discussing the step-by-step procedure of how to drill through metal using this technique. After reading this article, you should learn how to drill through different types of metals with ease.

Total Time: 9 Minutes

Step One: Prepare the material being drilled with some small amount of oil or solvent.

Step Two: Take the first step bit and tap it on the surface you intend to drill. If there is no oily or solvent residue on the surface, there should be no problem with that. Continue with the tapping until the bit has reached the bottom of the hole.

Step Three: Stop the drilling when the bottom of the hole gets close to the edge of the metal sheet. Stop the drilling by turning the hand crank slowly. In the case of steel or copper, the drill bit should come out of the hole directly. Otherwise, a gas leak will take place, and the device will become useless. In the case of steel, the drill will become useless if you drill any further.

Step Four: Apply some petroleum jelly or lubricant onto the rotary screwdriver bit. If the oil is too thick or greasy, the grease will cause the bit to turn funny. Strip off some of the lubricants and start again. On the other hand, if the oil is too thin, it will not have a good effect on the drill bits.

Step Five: Now you have drilled into the metal, stop the drilling and apply some pressure on the head of the drill bit. When the metal shard changes its shape, you will find that it is no longer parallel with the surface. It means that the shard is now slightly concave. You will have to roll the metal back and try to tap the concave areas using your fingers. Sometimes, you will get a small amount of relief if you tap hard. It is challenging to drill into metal that the electric arc has melted.

Step Six: The next step involves drilling holes into the metal. You will have to add some additional drill bits to the hole. Press the drill bit into the hole. When the shard has concaved into the hole, you can quickly push the drill bit out of the hole. When you are drilling into metal, which has been hammered, you might need additional power to drill the hole. You will need to take care when you push the drill bit out because you might cause damage to the surface.

Step Seven: You can try to twist the drill bit by placing it in the opposite direction of the shard you were drilling. Sometimes this will make the hole bigger. You will need to keep twisting the bits by moving them in a clockwise direction. It will cause the drill bit to dig deeper. You will be able to find different types of bits to help you accomplish this task.

Some people are satisfied with the performance of carbide-tipped bits, while others prefer diamond bits. Some people will mix diamond and carbide bits. A professional would never mix these two very sharp things. It is very dangerous when you drill into the metal hammered or have metal particles in it.

After all, I will assume that you are looking for one of the most useful and least expensive tips to hole a nail. That would make sense, right?  Look at the situation of drilling holes into your own body, and you may realize that there are much better choices than drilling holes into metal.

Let’s say that you have nails sticking up through the sheet metal supposed to hold them in place. You could use a regular drill to drill those holes and hope that you hit the nail and the hole. It will cause damage to the drill bit, or even worse, injuries. The safest thing would be to use a special nail drill, called a taper bit. It will sink into the nail, but it won’t break off as you drive it deeper.

When you have a professional metal digger out, they will use a drill that looks like this. It has a bit that looks like a corkscrew and a blade on the other end that looks like a drill. These types of drill bits are made out of the diamond. Diamond doesn’t break off as it drills into metal; it holds its shape. It is safer and more efficient than a regular drill bit.

Next, you will want to consider using a drill press. A drill press is similar to a drill, except it has a holding tube and a drill head in a cylindrical form. You put the drill bit into the holding tube and use the cylindrical top of the drill bit to guide it through the metal. If you are using wood, you might not use this method, as wood is not an open metal. If you are using steel, though, you can drill into metals with no problem.

It is similar to the drill bit above, but you drill an actual hole in the material. This drill bit is different, though, and is much longer than a regular drill bit. Because of this, it won’t necessarily get as far into the material. This type of drill is good for getting into extremely hard or thick material.

It is the tip for drilling holes in metal that you use when working on larger holes. It is your favorite tip because you will be able to get right down into the material and get a good solid grip on it. You can drill up and down and make circles, all while keeping your hands secure on the drill bit. It is essential to keep your hands steady because if you lose your grip and your drill bit slip, it could very well ruin the piece you are drilling.

This tip requires that you have a very long drill, over three feet. This type of drill bit will usually get very deep into the material before it wears out. It can be used when you are drilling on soft metals or plastics. It works so well because you don’t have to use as much pressure as you would if you were drilling on harder material when you are drilling. It prevents any from slipping away.

Hopefully, those tips have been helpful to you as you seek to learn how to drill holes in metal. There are a lot of other types of drill bits that you can purchase for yourself, too. Just make sure that the ones you buy are designed for the material you need to drill into. If you don’t take the time to learn about your drill, then you might end up spending more money than you needed to. Keep learning about the topic by studying some of the other tips out there.

Tip#1 Types of Drill

There are four types of drill bits: Titanium Nitride, Black Oxide, High-speed steel, and Cobalt steel. Based on material, drill bit usage also differs. These four bits are the drill bits for metal.

All standard bit will work fine with materials for drilling holes. But for metal, an HSS material bit is required because during drilling bit should not be broken. The reason for using HSS material is because of its heavy-duty nature, and it can bore many holes in a minute without heat and pinch. These drill bits have Titanium Nitride (TiN) coating. Because of this coating, heat production is low. It can last up to six hours for boring holes.

Tip#2 Safety

Drilling metal is not a tedious process, but those fragments of metals will cause severe damage to your eyes. So, remember always wear goggles and safety gloves to protect yourself from those tiny monsters. Pick your eyeglasses that cover the side faces too.

Tip#3 Create a Dimple

Usually, metals have a smooth surface, so they start to wander when the drill bits for metal touch the surface. So to avoid make a dimple on the surface. Measure and mark the position and use a punch and hammer to make a dimple on the surface. So after that, use a metal drill bit to make a hole.

Tip#4 How to drill a hole in Tile

Like metals, Tiles need to drill holes. You can use the HSS bit too. But use it at a slow speed. For mounting towel bars, bathroom accessories and shower doors need drilling holes in the tile.

Tip#5 Lubricate the metal drill bits

If harder metals are used for drilling, 1/8 inch thicker metal, use lubricant or multipurpose oil to grease the drill bit. Lubricating the drill bit for metal decreases the friction and heat dissipation, and also it makes the drill bit bore a hole quickly.

Tip#6 Clamp it

Remember, always use clamps to hold your work material, don’t use your hand to keep the metal. Since the drill machine is super fast, if you hold the material in your bare hand, there is a chance for an accident. So, to avoid such an incident, always use clamps to hold your work material, more than safety clamps will hold the material firmly and endure the machine speed.

Tip#7 Take a tiny step

If you need to bore a huge hole, then start with a smaller one. Usually, you will get a hole drill bit for 1-inch diameter, don’t start straightly with that; use a 1/4-in bit to bore a hole and then use other bits to enlarge the hole of your desired size. Always. Start your boring holes with smaller ones, and then go for the big shot.

Tip#8 Deburr the hole you made

Whenever a new hole is bored in a metal surface, sharp edges and residues will be there. Use more significant metal drill bits and twist and turn over the hole with your hand to make it smoother. The reason for the deburring hole is to avoid scratches. So that smooth edges results in a smooth process.

Tip#9 Use hole saws for big holes

If you wish to bore large holes, use Hole saws for perfect and clean holes. Like twist bits, hole saws place at drill bit for stainless steel; it will cast a neat hole in sheets like steel and aluminum. To avoid residues, use plywood to know the depth and to secure your workpiece.

Tip#10 Slow and steady

If the steel drill bits run faster, then it gets hotter soon. And the heat will make the bit less sharp. So, for metals, it is highly recommended to run your bit slower than possible. For hard metals, a slower speed is needed. You can drill the metal with 3000 RPM for smaller metal. For larger, 350 to 1000 RPM is appropriate.

Tip#11 Create a sandwich

For a perfect hole in a thin metal sheet, create a wooden sandwich. Place your metal sheet in between this wooden sandwich and clamp it in your workbench. This wooden bread layer is a perfect partner to make a clean hole. Since the wooden surface is corrosive in nature, the drill bits for steel will never wander around; it will help you to bore a hole in the perfect spot without a miss.

Tip#12 Give a try with a Step bit

Step drills are specially designed for sheet metals and small thin metals for boring holes. It will provide a perfect and clean hole regardless of size. You have many options if the size is considered in this drill bit. Actually, it is a bit costly. The expensive drill presses are the floor-standing model. Still, you can buy a clean benchtop assembly for about $100 bucks.
