If you are one of those people who occasionally do some repairs at home, then having a power would be a great help. These power drills are used in drilling a hole in various surfaces or materials like wood, glass and even metal or steel. And in order to do this, you need a perfect drill bit set for your needs.

Basically, drill bits are cutting tools that are used in making cylindrical holes. These cutting tools are held in power drills that rotate them into the surface in order to make a hole. Most drill bits come in set that contains steel spiral bits that can be used in almost all your drilling needs at home. However, these drill bits cannot drill into concrete or metal surfaces as they require special type of drill bits for this purpose.

Drill bits usually come in standard sizes that usually range from 8 millimeters to 32 millimeters. They can actually be made to order various sizes, but standards organizations have classified sets of sizes that are produced on a regular manner by drill bit manufacturers and sold by various distributors. In the US, fractional inch and gauge drill bit sizes are commonly used. However, in other countries, metric sizes are the most common.

Aside from various sizes, these drill bits for metal also comes in various types as well. This usually ranges from simple bits used in drilling sheet metal on home projects to the specialized cobalt coated bits that are used in drilling hardened and heat treated metals. This is why knowing which type of drill bits will be appropriate for a certain type of metal is necessary in order to come up with the best results.

Here are some of the most commonly used drill bits intended for metals and their uses:

• Cobalt drill bits – This is considered the best drill bit for hardened metals. It is also ideal for use where high temperatures are usually created from drilling stainless steel. However, the downside of this type of drill bit is their coating which makes it a bit brittle.
• Zirconium coated bits- This type of drill bit offers extended drilling power. It decreases the friction and makes precision drilling projects easier to handle. However, this type of drill bit is a little bit expensive.
• Solid carbide drill bits- This is perfect for the most common drill applications, but these bits cannot handle hardened metals and some heat treated steel.
• Titanium drill bits – This type of drill bit stands up well to heat and their coatings help in dissipating heat. This type of drill bit is also expensive than the other type of bits.

Those people who are interested in buying their own drill bits, you may check your local hardware as well as various online stores like Amazon.com. They have a lot of brands of drill bit sets that you could choose from. Some of the popular brands include Dewalt, Bosch, Craftsman, Irwin and Milwaukee drill bits. Just make sure that you are buying the type of drill bit that matches the material or surface that you intend to put a hole into.

Tired of drilling through stainless steel type metals or extremely hard surfaces like cast irons? Then this type of drill bits is for you. They are called cobalt drill bits which are designed and constructed for use in very specific applications. Cobalt drill bit is made to work at speeds 30 percent higher than the other high speed steel (HSS) bits while it resists heat and has a thick design. They are also a higher form of HSS bits which can drill almost anything including hard materials.

The difference primarily with the other drill bits is that it is made on cobalt element making it more heat resistant than others. Cobalt concentration are from 5% – 8%. This depends on the specification of orders in which the drill bits are to be manufactured. These drill bits prove to maintain temperature and sharpness despite drilling into hard materials.

The main advantage of cobalt drill bits is that they are the strongest type of drill bits around. Because of the high content of cobalt used in them, drilling through stainless steel, aluminum and iron may just be an easy task. Surprisingly, a single cobalt bit is known to drill through more metal than three or four other drill bits. As it is known, when clashing between metals, the strongest metal usually wins.

Cobalt drill bits also lessen heat brought by the friction of drilling. As a drill bit warms up, it becomes softer. So the quick lessening of heat with cobalt drill bits allows it to drill much longer and even faster. Also, since it is made of cobalt, an alloy known to be long-lasting, the drill bits can last for years compared to other high speed steel bits.

Here are some companies offering a cobalt drill bit set: Shanghai WW Tools Co., Ltd. which is good in their craft because they continue to improve and develop their innovations of drill bits; check out Hangzhou Tercel Imp. & Exp. Co., Ltd., which has an expertise in promoting drills in the field of cutting tools; Vorex Tools, on the other hand, are offering more competitive prices, high quality and superior service to the market whose extensive branches are found worldwide.

Qingdao Best-selling Tools Co., Ltd. offers a more friendly approach to their marketing;  Jiangsu Feida Tools Combine Stock Co., Ltd. has been in the business for more than 15 years specializing in manufacturing kinds of cutting tools; and Shanghai Greatcutting Tools boasts of prompt delivery, consistently high level of quality and excellent price deals where they can customize special tools just for you.

When it comes to household and industrial tools consumers must look at several aspects of the product. Most of the time, people get confuse which product to choose from and often they choose the popular brand or end up buying expensive ones.

Cobalt drill bits are most commonly use for drilling on stainless steel surface, automobile body, sheet metal or even some wood surfaces because of its amazing properties. One it maintains its hardness (temper) even at higher temperature which is ideal on metal to metal contact. This is important because the user doesn’t need to replace his/her drill bits often (save money). This drill bits may come in batches – cobalt drill bit set containing different sizes suited for different holes you like to make.

Important aspects to look at before buying a cobalt drill bit set are:

1. Size
In the U.K., drill bit sizes are categorizecod using the metric system. They have Standard measurements being use (British Standards) for setting diameter of drill bit sizes. In the U.S. fractional-inch measurements are commonly use by manufacturers. You would commonly see a 5pc. drill bit set with 5/64″, 7/64″, 5/32″, 1/4″ and 19/64″ or a 29 pc set with measurement range 1/16” – ½” with 1/64” increments.

It is essential to know which size (diameter) of cobalt drill bits you need to use so that you can optimize the number of bits to buy. You don’t need to get a 10 or 29 pc of cobalt drill bit set when you can get the correct bit size in the 5pc. set. It takes a little common sense but you can save some money by doing so.

2. Price

Obviously higher number of drill bit pcs. Commands a higher price than fewer drill bits. However, you must also realize that some generic or lower quality bits can be sold for cheaper price than quality branded ones. This goes the same as a good quality drill bits don’t need to cost much. Sounds a little confusing eh?

The key is to research for information, which cobalt drill bit set commands a good quality for a lower price. For example, you can get a 29pc. M-35 Irwin cobalt set for $80   compare with almost $200 on some leading brands. Irwin is a great industrial tool maker with years of experience on this business. It’s one of the best brands to look for when buying drill bits.

3. Quality

Product quality must be your top priority no matter what. Some people may find cobalt drill bit set quite expensive for their budget and decide to settle in for cheaper and ordinary steel bits. Soon, they realize that investing a little money for best quality cobalt drill bit set will pay for itself in the long run.

Veteran machine shop owners can attest to this fact since their business revolves around drilling and metal works. Excellent and high quality drill bit set is a must if you want to minimize your overhead cost and unnecessary expenditures.

Choosing a cobalt drill bit set seems to be a little expensive at first glance. The buyer must weigh-in his her options such as the amount of metal work to be done and period you need to work on a project. Perhaps, a simple and cheap drill bit set can be used for an overnight project. However, if you’re going to start your automobile or metal sheet business, it’s good to invest on quality cobalt drill bits. You can’t go wrong with them.

Finding the drilling bit for the job at hand might be confusing at first. I find myself quite confuse whenever I go to a hardware store or browse the internet to find the right drill bit set to accomplish the task at my backyard – very simple like punching holes in my kitchen sink, barbeque grill or fixing my kid’s toys. I’m a technical guy but still it’s like solving a difficult puzzle whenever I dare to find the correct and accurate information on what drill bit to find.

First in the list of my bucket full of questions is what’s the difference between a HSS and a Cobalt drill bit set? Aren’t they the same? Can I use one instead of the other? What’s the advantages and disadvantages of each? I’m sure some of you may have asked the same set of questions before.

There are tons of information in the internet, what I’m quite surprise is that there are sites that discuss only a piece of each equipment e.g. they only discuss Cobalt drill bit set or only HSS drill bits but not try to attempt and put this two together. Other drill bit forums prove to be helpful on this type of questions. You can ask your questions directly. Unfortunately, some guys don’t have any idea what they are saying. But then again, you have to separate apples from oranges I guess. Thus, I thought of providing a great information on the similarities and differences of the two drill bit types. Believe me, it isn’t technical like you’re thinking.

HSS Drill Bits

HSS or High Speed Metal drill bits comes in different shapes, sizes and functionalities too. In the case of drill bits the common shape we see is the twist drill bit type, with the size it may run to as little as 0.8mm to 12mm and up. Most drill bit materials use similar elements (metal alloys) to create them. Each were manufactured to accomplish a particular task. You may hear carbon type drill bits and High carbon type drill bits. They were named as such because they have higher Carbon element in them. For HSS drill bits, it compose of Iron (Fe), Carbon , Molybdenum, Tungsten, Chromium, Cobalt and others. Increasing the concentration of an element changes the property of the drill bit like its temper (hardness), flexibility, heat resistance etc.

HSS drill bits has greater performance compare with Carbon drill bit types in “higher speed” drilling because it can stand higher temperature without decreasing its temper (hardness), can drill the holes faster and doesn’t get blunt easily.

High Speed steel are used not only on drill bits but in some common household tools like knives, saws, gear cutters and taps because of such amazing property. However, HSS drill bits can only withstand high temperature setting up to a point and beyond that these drill bits may lose its hardness and drilling efficiency. That is where a Cobalt Drill bit comes in.

Cobalt drill Bits

Cobalt drill bits are special type of HSS drill bits. This means that on manufacturing a cobalt drill bit set, a higher concentration on Cobalt element is made making the bits more heat resistant.

Usually, Cobalt concentration ranges from 5% – 8% depending on the specification of the drill bits to be manufactured. The advantage of cobalt drill bits can be seen on Stainless steel surface and other thick metal surfaces. These type of drill bits prove to maintain their temper and sharpness on the entire task.

Of course, cobalt drill bits do have limitations – and that it is more brittle than regular HSS drill bits. Thus, when you’re buying a set of drill bits you need to weigh-in these factors. For example, what type of surface are going to deal with? Stainless steel? Wood? Kitchen sink? Because, if you’re going to buy an expensive 150 pc. Cobalt drill bit set and you’re only planning to use it one time then you might be better with a good HSS drill bit set or just limit the cobalt drill bit set to lesser number of bits.

Planning ahead is a great way to accomplish this task so you won’t have to waste your money on a tool that isn’t practical to use in the long run. If you’re in a drilling business then that’s a different story as well. Knowing the differences and similarities of HSS and  Cobalt drill bits will make you decide the right tool you should buy.

Drilling is one of the most common household jobs almost all Americans and the rest of the people do. It is one of the most important step to punch holes either to wood, stainless steel, plastic, concrete and other materials you could think off.

On every drilling chores there are important elements/components one should have to accomplish the task. First is the drill – the machine that contains the motor which produces the power to drive the drill bits. Second is the drill bit – this is the shaft that bore the cylindrical hole on the surface we want to. There are many types of drill bits available in the market some of them made specifically to accomplish the job better than the other.

Some materials use for drill bits are diamond, wood, carbide, masonry, steel alloy , cobalt drill bits and others. All of these drill bits have similar action – to drill holes although some do have advantages on some materials and external factors like heat, durability and price.

There are many things we can talk about drilling in general but for the benefit of our readers who are specifically looking for information on Cobalt drill bit set then we’ll focus on that.

Cobalt drill bit set comprise of multiple sizes of cobalt drill bits specifically measured to accomplish the job at hand. Some may think that cobalt drill bit set are just cobalt metal coated on the surface of the steel bit alloy. This isn’t so.

Cobalt drill bits are manufactured by combining cobalt metal (usually 5%) with other metal alloys making it more durable than you could think of! At the end of the manufacturing process these cobalt bits are baked into an oven to make the surface colored off-gold. The purpose of which is for easy identification of the bits.

Advantages of cobalt drill bits

Strength and durability

Cobalt drill bit alloys do have high strength and durability compared to most drill bits. These bits are best suited for making drill holes on surfaces like iron, aluminum and stainless steel. A Cobalt drill bit set will indeed save you money in the long run since it will bore more holes on these metal surfaces than other softer drill bits.

Disperses Heat Well

Cobalt drill bits have excellent performance on dissipating heat very quickly compare with other drill bit materials. That’s the exact reason why you should get a cobalt drill bit set to do metal to metal (especially stainless steel surface) drilling. Some drill bits tend to soften when drilling against a metal surface making them less effective. Again, purchasing a cobalt drill bit set will save you more money 2-3 times than other conventional steel drill bits.

They last longer

Some may find these type of drill bits cost more than other steel drill bits. However, due to cobalt drill bits’ material composition it will last for years with proper maintenance saving you more bucks. Maintenance is quite easy too, just sharpen your cobalt drill bits once it gets dull using cutting fluid and you’re good. These type of drill bits may even prove to last longer than titanium-coated and HSS (high speed steel) drill bits!

Knowing what type of drill bits you need to accomplish the job is the key on finding the right deal. Cobalt alloy bits are one of the best drill bits you can invest your hard-earned money. It will finish the drilling task perfectly each and every time saving you time, money and headache.
