For drilling you have many complications, one may face problems at the time of drilling. Therefore, there are step drill bits for short convenient drills. If one doesn’t know about it and doesn’t know, how to use step drill bits? Here, this article is for him.
Confusion arises in one’s mind when he thinks of drilling. If someone does not have any idea of the size of the bits, then no need to worry, step drill bits are the perfect solution. They have measurements on them.
They can easily make holes in metals, plywood, wood, plastics, and many other surfaces. For its variation, it has become famous. Now, take a look at its working procedure.
What Are Step Drill Bits?- Measurements And Structures
Step drills or unibits are perfect for drilling holes in the metal surfaces. It is one of the most convenient drill bits to make a hole or enlarge the existing hole. The step drill bit is ambiguous equipment in the drilling sector. However, some love it, but some people don’t like it.
Drill bits are pieces of equipment that assist a drill to make holes in hard surfaces. Among the drill bits, there are step drill bits that have the measurement of how much you want to drill. The structure of step drill bits is-
- Pointing angle
it is the head or tip of the drill and the most important portion. Mainly, because of the pointing angle a hole creates. This pointing angle is of two edges of the groove profile.
- Groove profile
It does an important job at the time of drilling. This removes the chips when drilling a metal surface, the part that is removed is taken up by the profile of the flute or grooving profile. It is necessary, otherwise, the drill bit may burn out.
- Grades
Starting from the pointing angle, the grades start to increase, for which their diameter increases. Moreover, in step drill bits, there are measurements in each grade that assists to make a hole perfect. The size of the smallest grade is six nanometers and the largest one is of twenty nanometers.
- Shank
In the last grade, there start a shank that connects the drill with the bits.
How To Use Step Drill Bits: Precaution And Procedure
step drill bits can do a variety of holes in the sheet you want. They are popular for their diversity in making perfect sizes of holes in metal sheets alongside thin materials. Therefore, you need to know about the use of these drill bits.
- Health Precautions
While drilling, you need to take safety precautions, so that no accident occurs at the time of drilling.
- Safety glasses
wear the glasses at the time of drilling, otherwise, the metal chips may enter your eyes. Besides, this may cause injury to your eyesight, you may lose vision too.

after taking all the necessary precautions, start the procedure of drilling. Before drilling, choose the perfect bits for your surface. Choosing the bits according to the thickness of your surface will make it perfect. Here is the procedure.
- Clasp the object
before drilling holes in the surface, you have to ensure a good grip on the surface. It will help the step drill bits to drill perfectly. It mainly assists the drill in not slipping due to the pressure of the drill.
- Pointing the center of drilling
using a center point for precise drilling is mandatory. For avoiding drilling in the wrong place and making a perfect hole with the proper diameter, a mark is a must.
- Adding oil
drilling on a metal surface is never that easy. It sticks with the groove profile and may create accidents. Therefore, use lubricants for smooth drilling with unibits.
- Drilling of holes
after performing the above procedure, connect the drill with the power connection and ensure proper connection of the shank. After that, use a small drill to make a point hole, if requires.
Start drilling slowly, do not fasten the speed of drilling immediately. After getting closer to the desired hole, slower your speed and stop at the perfect time. At last, clean the surface area so that there are no shavings.

- Smoother holes without any shavings.
- Proper holes with fewer complications.
Should I step a bit fast or slow?
Most people do the same mistake by drilling with the strep bits too high. As it can precisely make holes in metals so, low speed is preferable. At first, you have to start it slowly, then increase the speed gradually.
Can I use step drill bits in the woods?
Step drill bits had diversity and various applications. As they are costly products, they support drilling in plywood, acrylic, and in wood too. Therefore, one can easily drill in wood using a step drill.
How is a step drill bit used?
Step drill bits are designed to drill holes in thin materials such as sheet metal or plastic. They are commonly used for secure the workpiece, mark the hole, increase the diameter, begin drilling, deburr the hole, and more.
Final Words
Drilling is an important work that helps in maintaining our household chores. In drilling, there are many complications a mechanic faces such as- the proper width, and depth of the hole. This is not a problem when one uses step drill bits. But if you don’t know how to use step drill bits, read this article.
Moreover, step drill bits will provide varieties applications in surfaces which facilitates much more. However, proper use of these bits will lead to a perfect hole that will assist in your work.
