12 Best Step Drill Bit For Wood & Metal In 2021

If you have used a drill machine, you must be familiar with various types of drill bits. In any standard hardware store, you will find a dedicated section for drill bits where you can find hundreds of options. But, the main problem with traditional drill bits is that you would require a separate drill bit for every hole. Even though you can drill holes of larger depth with the drill bits, it is not ideal for drilling holes of various diameters simultaneously.

For that, the best option is a step drill bit. These bits offer multiple sizes on a single bit which makes the task a lot easier. With a standard set, you can get up to 50 drill sizes at once which allows you to create holes of varying diameters with ease. Today, we will be looking at some of the best options you can possibly find in the market right now. But before you buy one, make sure you keep the following things in mind.

  • Supported Sizes: One of the most common reasons to buy a step drill bit is the versatility of the application. Therefore, you must check the drilling sizes available with the set. There are a lot of options that offer multiple bits in a set which will grant you up to 50 options for drill sizes at once.
  • Finish Type: The finish type is also an important factor for drill bits. For any contact type too, the tool itself needs to be harder and stronger than the workpiece. Checking the finish type of the drill bit will let you consider the possibility of applications before you buy the unit.
  • Reliability: As we mentioned earlier, the contact type tools must have a strong build quality to offer a reliable experience. Apart from the build quality, you should also consider the assurance provided by the manufacturer on the unit. You can also prefer options from popular brands as they are currently being used by thousands of individuals.

Today, we are bringing you the best drill bits you can find in the market right now. While you go through our list, you will find the best options along with all the information that you need to know before you buy one. We will also include a “Buying Guide” for the same so that you can get more information about the specifications and properties of a step drill bit.

Buying Guide For The Best Step Drill Bit

If your routine job requires you to drill holes through metal, you must know the compatible options for drill machines as well as drill bits that are compatible with it. If your work requires drilling holes of the same depth but varying diameters, it is recommended to switch to drill bits right away.

These bits are designed in such a way that you can drill holes of multiple sizes without needing to change the drill bit. This is a major advantage over traditional drill bits where you have to carry a large set of drill bits to the location of operation. Apart from that, there are many other features that you should consider before you buy the step drill bit set. We will be featuring all of the required information on our buying guide present here.

1. Material

The material used for the construction of a tool is a major factor for all types of tools. The material used for drill bits divides whether it can drill a hole through a particular workpiece or break in half within a minute of operation. For step drills, you should prefer the ones that are made up of high-speed steel if you are going to drill through soft materials like aluminum and plastic. For heavy-duty applications, you should go with cobalt step drill bits. Even though these drill bits can withstand intensive applications, a lot of tools including drill bits fail because of improper application.

2. Drill Bit Shank

The shank is basically the body of the drill bit which is held by the drilling machine. The shank portion of the tool represents the plain area that you insert in the machine before locking it in place. The shank has a specific diameter and your machine must support the shank of the drill bit in order to use it. If the drill bit is incompatible with your machine, there is no point in buying the bit. You can find out more about the compatibility of your machine on the machine itself, or the official website of the machine manufacturer.

3. Available Sizes

One of the major advantages of a step drill bit is that they offer a range of sizes for drilling a hole without needing separate drill bits. But, it is recommended to check the sizes available with a particular drill bit or set of drill bits before you buy it. A set that offers a diverse range of options will be comparatively more versatile in application and will offer you better value for your investment. However, make sure that you are not overpaying for a set that is not going to be much of a help in the future. For hobbyists and casual users, a single drill bit with about 10 variations in size should be the perfect option.

4. Finish Type

Lastly, we will talk about the finish type available with a particular step drill bit. Almost all of the drill bits that we have mentioned today offer titanium finish which is quite popular in the industry. As you may already know, titanium is a significantly stronger element compared to most standard elements used in construction and manufacturing. Therefore, a step drill bit will get the job done for you in most cases. Titanium coating on top of the tool reduces the friction between the tool and the workpiece and makes the drilling process less straining for the tool. You will also get a prolonged lifespan on a titanium finish tool.

Frequently Asked Questions

1. Is a cobalt drill bit better than a titanium drill bit?

Ans: The material of the drill bit should be chosen with respect to its application. Titanium drill bits are considerably more popular in the market as they allow you to swiftly drill through soft metal such as aluminum. But for workpieces like cast iron and other similar hard metals, it is better to switch to a cobalt drill bit to avoid damage to the drill bit.

2. Are drill bits suitable for thick metal workpieces?

Ans: Step drills surely allow you to drill different sizes of holes without changing the drill bit. But as the name suggests, drill bits will result in step holes, which means the diameter will vary when you reach the depth limit for a particular size. Also, drill machines are not recommended for thicker workpieces. You should rather prefer a drill press for heavy applications.

3. How to sharpen a drill bit?

Ans: If you do not know already, it is recommended to sharpen your drill bit time after time. When you use a drill bit, its edges are scraped off along with the removal of material from the workpiece, making the tool blunt after a particular time. There are a lot of ways of sharpening a drill bit. Out of which, the easiest and most popular method is with a bench grinder. If you sharpen your drill bit at set intervals, you can expect a longer lifespan as well as quicker operations with the drill bit.

Conclusion:

There are a lot of drill bits that can put a hole through a variety of materials like ceramic, plastic, wood, etc. But when it comes to metal, the selection of drill bits available for the job narrows down to the strongest option as drilling through metals generates a lot of heat and friction.

Also, the drill bits must be made up of material that is significantly stronger than the metal itself. Today, we have brought you a selection of the best drill bits which will get the job done for you. If you are not sure which option is perfect for you, take a look at our buying guide to get an idea. Alternatively, you can check our recommendations present right here.
