One of the most common tools used for cutting metal is handsaw. The most known features of hacksaw are, that can help you in recognizing it, a rigid frame in C-shape attached with a handle. A thin blade that is mostly flexible runs through the open portion of the saw. The teeth of the blade vary in terms of size. Space between the teeth of the blade is also different in different type of hacksaw.
Therefore, by keeping in mind the size and composition of metal you are about to cut, choose the type of hacksaw. If you are cutting a thin or soft metal, small blade teeth that are close to each other can be used. Such hacksaw will give you fine and precise cuts.
On the other hand, if you have hard or thick metals in your hand for the cutting job, a hacksaw with large blade’s teeth that are spaced widely is ideal to use. Such a blade will give you coarse cuts. It is important to choose the right hacksaw to get the desired cuts.
Handheld Circular Saw
A standard mechanized circular saw is perfect for giving straight cuts to almost all types of metals. Well, the important thing to keep in mind to get most from the handheld circular saw is to select the right blade according to your project. Mostly, in metal-cutting projects, a circular saw is perfect.
In a handheld, a toothed or abrasive blade is attached motor spinning and rotating continuously. You will get accurate and straight cuts by using this circular saw. The saw may leave burrs on the edge of the metal; you can use sandpaper to remove burrs. It is recommended to keep the setting of the circular saw geometrically. The metal you want to cut, clamp it securely or hold in a vice. Move the saw slowly in it.
As each of the tooth on edge will strike the material, it will cut the material. The tooth will cut off the material rather than binding it in the metal piece.
Metal Chop Saw
You will rest the metal piece on the stationary base, and the saw will lower down through the object. A metal chop saw is designed in such a way that it can bear sparks, heat and other kinds of metals. However, it is not recommended by the manufacturers of a metal chop saw that you attach the cut-off blades with the equipment of woodworking.
The design of the metal chop saw is similar to other tools used for woodworking. An abrasive disc is used in the chop saw for cutting off materials. There are various configurations in such type of chop saw; it can be free hand, walk behind or table top types. Tabletop chop saws are most common that are used for materials like metals.
The position of the blade in the grinder makes it distinct from other types of a portable saw. The blade is not attached perpendicularly to the motor; the blade of a grinder is parallel to the motor. The position of the blade makes it easy for metalworkers to do sweeping force and can cut the metal with a better force.
The different grinder has different size of discs ranging from few inches to a foot. There are many different types of grinders like belt grinder, bench grinder, surface grinder, jig grinder, gear grinder, tool and cutter grinder, etc.
You can also use a reciprocating saw for metal cutting by mounting a metal cutting blade in it. Now you can cut metal rods, bolts, and pipes. You can also use a reciprocating saw with a metal cutting blade during demolition work when pipes and nails are involved.
You can increase the life of the blade by keeping its speed slow. Carbide tooth and bimetal blades are perfect for increased blade life.
