Step drill bits are unique types of drill bits that range from their tip to their base in diameter. They look like a small pine tree. Such drill bits have tips that are drilled to a different diameter so that for variable diameter holes they can be used.
The two main types of drill bits are counter-bore and countersink drill bits. The counter-bore is a straight slide between the surface diameter and the main diameter. Countersink drill bits are slightly angled.
Step drill bits have various applications. Although they are quite costly than other drill bits. Step drill bits are mainly designed to drill metal sheets and wood.
It's very easy to use a step drill bit if you know the basics. You just need these measures the following steps:
You must distinguish step drill bits between different types of surfaces while working on metal, wood, or even an alloy. You would need a separate step drill bit for stainless steel, a separate step drill bit for wood, and a separate one for aluminum or iron.
At the exact point where the hole is to be drilled, you need to position the tip of the center punch. If you have the exact position, you can strike the blunt end of the center punch with a hammer. This will have a clear location for the positioning and capture of the drill bit. It will make sure that the drill bit does not swing so that you can operate in the right position.
First, ensure that the drill bit is matched with the center mark and press down on the trigger of the drill. Make sure that the tiny drill bit passes through the metal sheet or wooden sheet all the way through.
Putting constant pressure on the drill bit is not appropriate. Therefore, when you are drilling take short intervals. This is not only to give the machine rest, but it is also to add some tapping fluid to keep the drill cold. It may produce sparks or damage the surrounding material if it overheats.
You must remove the step drill bit from the motor after the drilling. To remove any metal shavings, you should then continue to clean all the drill bits and the motor. Also, clean these metal shavings from the hole that you have drilled as well.
After using a step drill bit for metal, you must well polish it before store. For storage use the standard drill bit container. This will secure the drill bits more properly for further usage and extend the life span.
There are many advantages of using a step drill bit for drilling. But, there is always a second side to a coin. And you must aware of that side too. Here, you will find some pros and cons of using a step drill bit.
Well, That was all about a step drill bit and its advantages and disadvantages. We, assume now you are fully aware of using a step drill bit in the right manner.
