Saw: How to choose


Saws are very important item inside the toolbox or any workshop due to its ability to cut various types of metal. Many people looking for sawdust tend to struggle with deciding which one to buy.

Before buying a saw, it is vital to know the type of work you intend to use it since each saw serves a certain type of work. Using a wrong saw can spoil the part to be cut or give excessive work to anyone who is trying to say it.

That is why it is important to know the different types of saws available…


There are several types of saw designed to cut certain types of material. The main feature used to differentiate between saws is types of blades, but in other cases, the structure is also used.

Regular Blade

Regular cleat blades are the most popular among consumers, mainly due to the fact that the standard blade that comes with most serrated saws is the regular type. These blades are constructed for cutting low strength metals including pure aluminum or tin and characterized in that the teeth that are in contact with each other as well as a difference the left and right sides of the teeth.

Most people face difficulties in using this type of saw blade in the first couple of strokes, or until the surface of the metal gets accustomed to the nature of this blade. However, the work becomes easier from this point and you can cut the metal into several pieces with speed and precision.


Rake blades come with distinctive features that make them easy to spot by the teeth, which appear in groups of three. Even though this blade appears to be slightly different from most blades that most people are used to, it provides excellent results when used for cutting iron pipes and other hard metals.

It is important to know that raker blades are not the fastest available and usually require more effort to get your pipes and cut metals. However, no other type of saw blade gets the job done as efficiently as traces. Trying to use a regular blade to cut a hard metal such as iron tube only ends up disrupting the sharpness of your blade without delivering any results.

Wavy Blade

Wavy blades are designed to perform fine-cut on strong types of metals and, just like its name, the teeth come with a wavy design from left to right. It offers excellent results when used for fine metal cutting, but you should avoid using it as a substitute for a raker blade in heavy metal cutting jobs.


Getting the right hacksaw, even if it is a power tool or manual saw, is only the first step because you will not generate the maximum results from your cutting tool unless you are able to implement certain measures to ensure your longevity.

Use Right Strain

Most jigsaws will give you the ability to adjust your tension to meet your cutting needs and even after getting the right kind of blade for your job, using the right tension helps you leverage the power of your saw.

Remember, using the wrong voltage leads to the need to use more energy to get your metal cut. This is why it is important to adjust the tension so that your blade can be as tight as possible to ensure successful cutting even with a minimum of effort on your part.

The tension of your saw is adjusted by turning the butterfly nut located in the saw as much as possible until you get a certain level of tension and stiffness in your blade.

Another effective way to get a good grip on your tool is to use both hands simultaneously while cutting the material. This ensures maximum pressure on the saw blade so that it wears the material evenly along the cut and ensures precise edges.

Lubricate the Blade

Lubricating your saw regularly is another great way to ensure maximum performance while preserving it for long-term use. There have been many cases of saw blades that have ruptured due to excessive friction or excessive levels of uneven pressure on them. The good news is that there are many oils that can be used to lubricate the saw blades.

Reverse the Blade

Are you struggling to cut into areas that are extremely narrow? A great way to get to any area of metal with small angles is to invert the blade.

Teeth per inch

Each saw blade comes with a measurement on the teeth as it relates to the number of teeth available in every inch of its length. The teeth per inch should be used as a guide to determine the minimum thickness of material that a saw blade should be used for.

Types of Saw

When looking at the saw blades, it is important to also consider the frame, which comes in two main types: adjustable and fixed. A fixed frame comes with a specific frame length that can be attached to it, while an adjustable frame usually comes with a range of saw blade lengths that it can accept.

The choice of the frame is quite related to the saws you already have, but it is always interesting to opt for the flexible one to have more option.
