Do you know what a difference between the several types of drill bits?
And do you know what kind of that is the best?
You are not only one. Many people cannot identify metal drill bit of wood drill bit and for what it is.
I am gonna let you know all the necessary information about metal and wood drill bit.
What is a Drill Bit?
Let’s start with the basics.
The drill is a cutting (drilling) device, which finds application in creating holes in a material.
The drill creates round holes, despite it happens in different shapes and sizes. In accordance with this, we can get holes of any size and model if we use a drill.
The structure of the drill is not complicated. As a rule, it has a spiral part, a point angle, and a lip angle.
The spiral part is the most important part since it is this part that is used for control during cleaning of the bit from chips.
The spiral part can be fast and slow. If you want to remove the shavings from the material quickly, then you need a fast spiral. Need a low rate of chip cleaning? Use a slow spiral.
Such a part as a point angle is not less important part of the bit than the spiral part. When working with the solid material, you need to select a bit with a large point angle.
The reverse works with a soft material. In that case, you need a bit with a small point angle.
And the last part – the angle of the lips – is needed to adjust the support for the cutting edge. It will allow you not to damage the thread.
The length of the bit is not part of it, but it has a big effect on the bit’s performance. The length provides the depth of the hole that you are going to do with this bit.
In addition, material divides the bits. So, there are metal, woody bits, and many others.
Metal Drill Bits
Metal drill bits are needed to create holes in the metal material. Firstly, because using wooden bits for metal is extremely inefficient.
Therefore, metal bits are more powerful and suitable for drilling any objects.
It is also the main drawback – if you do not drill the hole to the end, the material can be destroyed due to the power of the metal bit.
In addition, metal drills are also different. For example, there are central and pointy bits.
Why use it? In order to mark the place for drilling. The fact is that the metal bits have a sharpened head, which you can use for the mark.
But there are also other types of metal bits. There is a Core bit and indexed bits. It is a multi functional bit that has two functions. You can easily make a hole on tough stainless steel surfaces.
This bit increases the hole of an already existing hole. And this bit is able to create an annular cross-section in the framework of cutting a hole.
In turn, the indexed bits have two inserts for the inner and outer radius of the hole. This type is suitable only for professionals. Black Oxide & Titanium bits are top quality metal drill bits.
Wood Drill Bits
The point is that the purpose of the wood bit is to create a hole in the tree.
Yes, the metal bit can also do this, but the likelihood that the material will collapse due to the power metal is high.
The wood bit does not damage the tree (as a softer material than the metal is), creating a hole.
And there are also several types of wood bits. There are drill bits and spurs. The second type is especially popular when you need to make a hole in the forest.
Both drills are designed to work with wood. It has a spiral to create a hole. That is, because of the work you will get a spiral hole.
There are also bits of the shovel of a flat shape, which are necessary for rough boring.
Have you ever heard of a bit of a spoon? It is also a wooden bit that has the shape of a spoon and a dotted corner. This bit polishes the hole made in the tree.
Metal vs Wood Drill Bits
We looked at the metal bits and wood bits. Of-course, both types have differences.
The first difference is in the destination. Wood bits are used for drilling wooden materials. Accordingly, the metal bits are designed to create holes in the metal.
The second difference lies in the limitations. Tree bits are limited in use, that is, it is only suitable for wood, but metal bits can be used for both wood and metal. However, metal bits can damage a more fragile tree.
It is important to note the force that is higher for metal bits than for wooden ones. Metal bits are more energetic and therefore require more pressure.
The pressure of the tree bits is much lower than the metal bits have it. Sometimes it may not be enough for drilling harder materials. However, the pressure of the metal bits is high and can damage the softer material.
How to Identify a Wood Bit from a Metal Drill Bit
As aforesaid, wood bits are not suitable for working with metal, since metal destroys a weaker bit. Metal drills are not suitable for wood, especially if the bit has a large diameter.
Does this really matter?
Metal bits increase the split when working with wood. It is important to note that it is this aspect that depends on the type of tree and the bit size that you use to drill.
So how to determine the bit so as not to run into the destroyed material afterward?
Wood drill bits have spar and lip. The spar allows the wooden bit to support the centering during drilling. It also prevents free movement of the bit during drilling.
And the lip plays the role of a drilling element. It works by cutting through the fiber material. This lip is designed to improve the finish because it reduces the blowing of the tree from the back of the hole.
Now you have an idea of what type of bits is intended for what kind of material and what benefit you can get from it.
I strongly recommend that you consider the bit size and type of wood or metal when you choose between the metal bit and the wood bit.
