Sawzalls are powerful and handy tools that are used for cutting. As experts say, it is the obvious choice for most people who consider cutting anything. The tool is also commonly referred to as the reciprocating saw. This is simply because it has a blade that works by reciprocation (pushing) and pulling. Saber saw is another name that is used to refer to this tool.
As we will be seeing shortly, the tool has been around since the 1950s. However, if you have been attending events where Sawzalls are put into use, you have probably seen how the users stumble. These users demonstrate varying expertise (skills) in using this handy tool. The most obvious situation is where people run it at high speeds. This withstands whether the user is a learner or experienced tutor. The result of this is that the teeth of the blade may get cut by some inches or the blade might become null and will necessitate removal and change (blade replacement).
We set out to discover why this is so. While in our adventure researching and using the best sawzall out here, we gathered important lessons that we would like to share with you. As your guess will be, not much thought is usually given to usage of this tool. We have also gone further to give you basics on how to operate the tool. But before we dig deeper, let’s understand the brief history of sawzalls.
History of Sawzalls
Sawzalls are said to have been invented in 1951. As we said earlier on, these types of saws work by pushing and pulling. Since its invention, a lot of adjustments have been done to this tool. So Many features have been added to to make it efficient. Some of the features that have been added include ability to change the blade quickly, battery power to run its motor, variable speed, adjustable shoe among others.
Sawzalls can be used in workshops, garages or at home. They are mostly used for cutting woods. However, you can use them to cut metals, masonry materials or fibreglasses. Remember sawmills are different based on the blade that is used. So, if you are considering this tool, make sure you take enough time to choose the best sawzall for your project. Demolishing things like windows, doors, walls are some of the projects that can be undertaken using sawzall. You can also use this handy tool in cutting down trees or unruly branches.
In most cases, sawzalls are sold for commercial uses. This is mainly because of their efficiency in cutting. However, remember that the best sawzall are made for different functions and usages.
How sawzall works
Sawzalls come with different features (component).
- We spoke about the adjustable shoe. This helps to prevent the sawzall from jumping around. The adjustable shoe also helps the operator to set how far the blade will penetrate into the item that is being cut.
- Quick change feature on the sawzall helps operators to remove and change blades just as the name suggests. This feature is very important as it helps in preventing delays as a result of the blade installed not working.
- Variable speed feature. With this feature, operators change blades depending on the speed that they need. They can change from 0 SPM to 4000 SPM. SPM stands for Strokes per minute.
- This is one important component for Sawzalls. Blades are used for actual cutting. Different blades are used for cutting different materials. In blades we have one measure which is called TPI (Teeth per inch). It is this measure that aides in designing blades to be used for different tasks. When there are less teeth in a blade, that blade will be used for cutting softer materials. A blade with many teeth is used for cutting fine materials. Be sure to check out these specifications when you purchase the sawzall. Another feature on blades to check is the thickness of the blade. A blade that is thicker has a long durability as compared to the thin one. Even heat that causes the blade to melt does not affect thick blades as such.
- The handle. This is where the operator holds. They direct the cutting using the handle.
- We also have other component like screws (which aid in holding the blade), the ON/OFF switch (for connecting power flow and disengaging the same), the switch lock (this is different from the on and off switch). Electric chord, the rocker shoe and stain deliver chord are the other components.
- When using a sawzall, make sure you protect your eyes by wearing safety glasses. This is because materials that peel off from the item you are cutting might injure your eyes. Experts recommend you shield your face completely
- You also need hand gloves. Hand gloves will protect you from the push and fort that comes from the sawzall when operating at full speed.
- Ensure you are having the correct blade for the project you are doing.
- Avoid touching the blade directly after the cut. Blade usually hit when cutting and if you touch immediately after, it might burn you.
- When changing the blade or any other component, first unplug the saw from power source.
- Remember sawzalls are hand held tools. They are versatile and powerful. Read safety and precautionary measures that come with the tool when your purchase.
