What is a step drill bit?

A step-up drill bit is used for drilling through metal at a slower speed. It rotates in a clockwise direction and can go through metal sheets that are up to ¼ inch in thickness. A step-up drill bit uses steps on the bits, each bigger than the one before, to drill through the surface. A step drill bit has multiple applications apart from drilling through metal. You can get a step drill bit for wood, plastics, aluminum, brass, and copper.

With a wide range of applications, a step drill bit set can be one of the most versatile tools you can have. Keeping that as our focus, what should you look at while shopping for one, and what is the best step drill bit? Let us try to answer both ahead.

What to look for while shopping for a step drill bit?

A couple of factors that you must consider while shopping for a step drill bit are as below:

  • Drill Bit Material: Depending on what surface you plan to drill through, you can choose from steel, titanium, carbide, high-speed steel, and cobalt step drill bit.
  • Point Angle: The harder the metal you plan on drilling through, the greater the point angle you will need.
  • Versatility: If you plan to work on various types of projects, you will need a drill bit that can make holes of different sizes. Choosing a drill bit with different size options helps you make the most of your investment.
  • Type of Shank: Shank of a drill bit is the end of the bit that the chuck grips. You have different types of shanks available, such as Hex, Round, SDS, and Tri-Flat shanks. Each shank has a specific application/use that it supports.

Answering what is the best step drill bit may not be as easy- but to ensure that you get the best one for your project, we have compiled features and reviews of the top 6 step-up drill bits ahead.

Step Drill Bit Buying Guide

As you go shopping for a step drill bit, there are a few things to be kept in mind. What to look for, how to pick the best one for your project, etc.- let us try to answer questions like these ahead.

What type of material you plan to drill 

If metal is what you will be drilling through majorly, then you need to specify what metals. Metals differ in terms of their density and hardness. High-Speed Steel drill bits are the ideal choice for sheet metals, aluminum, and cobalt. If you need to drill through metals at high speed, then you may need drill bits with titanium and/or cobalt coating. Cobalt helps decrease friction and provide faster drilling without much wear.

In case you plan to majorly drill through wood and plastics, then simply go for high-speed steel without cobalt. You will be able to get drill bits in a budget and get through the occasional metals as well.

Power tool compatibility 

The shank size and design are what decides the compatibility of the drill bits with the power tool. Many drill bit kits come with multiple shank-sizes and even universal bits so that they can work with various power tools. 

Point Angle

The point angle can vary from 90 degrees to 145 degrees. The harder the metal you want to drill through, the greater the point angle you will need. For most home and DIY users, 135 degrees is sufficient for taking care of almost all drilling needs. 

A few other things that you need to consider here include:

  • Choose a drill bit set that has laser engravings on them. This helps you to precisely drill as per your requirement.
  • A storage case helps you to organize and store the drill bits securely. Any quality manufacturer will provide that with the drill bit set without extra charges.
  • Cobalt and titanium coatings are worth the extra price and increase the life of the drill bits in the long run. Consider getting them even if you do not have an immediate need and can accommodate the increase in budget.
  • Do not just go with the one that has maximum size variety- ensure that the kit has the exact drill bit sizes that you need.
  • Before buying, check if the drill bits need lubricant and factor that into the total cost. 

FAQ

What does a step-up drill bit do?
A step-up drill bit makes it easy to drill through any surface, especially plastics and sheet metals. These are used for drilling precise holes more efficiently.
Can a step-up drill bit be used on wood?
Yes, you can use a step drill bit for wood with a thickness of up to 4mm. Any high-speed steel drill bit with titanium coating is enough to drill through wood with ease and precision.
How can I prevent the drill bit from heating up?
With harder surfaces especially metals, drill bits do heat up after continuous use. Use drill bits with titanium and cobalt coating to avoid heating and wear & tear. Adjust the drill speed to an optimum level – do not go with the highest setting if it is not required.

Conclusion

Step drill bits can be the most valuable addition to your tool kit. They can help you drill through a variety of surfaces with ease and precision. Therefore, it is important to take your time for finding the right one as per your project requirements and future needs. The drill bit sets that we covered above are just 6 of the best ones in the market- but you should be able to pick one that meets all your needs from among them. Do not base your decision on just 1 factor like the price or variety- make a balanced decision to get the most out of your investment. 

While selecting drill bits, do check for compatibility with the material and the tool you will use it with. Also, follow all manufacturer instructions for use, safety, and maintenance. This will help you get the most out of your drill bits and ensure that they last longer and continue to provide you with peak performance for several years.
