Tip & How-To about Saws
For every project that you want to work on, there will be a different set of tools that you will need to use. The hacksaw has different types of blades and frames that can be switched out for the different projects that you are working on.
There are three main kinds of blades that the hacksaw can use and each one has different benefits. The teeth on the hacksaw blade will range between 14 and 32 teeth per inch. The thicker the blade the fewer teeth there will be per inch on the blade. The types are regular, raker and wavy. Regular blades are good for soft metals that don't have a lot of metal and the teeth will be closed together touching and alternating left and right. The raker blade has teeth placed in sets of threes and are best used fro cutting through thick metals. The last kind of blade is called a wavy blade, on these ones the teeth are in a wave pattern that are great for making smooth cuts in hard thin metals.
When it comes to hacksaw frame types there are two types to look at the fixed frame and the adjustable frame. Fixed frames are only able to hold a blade of a single sized length of blade. The adjustable frame can hold different length blades typically between 10 and 12 inches. The blades that you will buy for a hacksaw will have holes on either end of the blade. These holes are used to attach and dettach the blades from the frame.
Whatever the blade that you are using make sure that when you are sawing through metal make sure that you go slow because rubbing metal on metal will generate a lot of heat and can spark. You can also ruin the blade on your if you are sawing too quickly.
