Metal cutting saws and band saw sale are used to assemble half-finished metal workpieces. Alternatively to sawing, cutting is an established process for shortening and assembling half-finished pieces. The main difference between the two approaches is how many chippings are produced during the process. Sawing produces a lot of chippings, whereas other separation techniques can be undertaken without producing chippings as a result. The choice of process is the concluding factor as to how precise the cut will be. The chipless cutting of sheet metal allows for a highly precise cut. With thick sheet metal, for example, rolled aluminium, the cutting process can also reform the material. This reduces the precision of the separating process. Shortening blocks, to shape them into the desired form, is a task for a metal cutting saw. Find a wide selection of used metal cutting saws up for sale from various second-hand industrial sellers, different locations at affordable prices. Several different approaches have been developed for metal sawing, which all produce different results in terms of quality, quantity and efficiency.

Used Band saws, Hacksaws, Circular saws, Hand saws, Metal Cutter etc. Check the second-hand metal saws specifications, manufacturer, prices and more info below. The used online market is full of great offers for a second-hand band saw sale.
The Function of a Metal Cutting Saw
A metal cutting saw is made out of a saw blade, whose material has to be harder than the material of the workpiece it will be cutting. Only the tips of the teeth have to be harder, but a diamond coating on the saw blade can enhance the metal saw. Saw blades for metal cutting saws have extremely small teeth. The size of the teeth is due to the hard and tough material that they are made of. Metal can only be separated in small stages. Large teeth would be bend immediately. The saw blade of hacksaw or bandsaw and reciprocating saws are in the form of a band. With circular saws they are round. Alternatively to a toothed saw blade, a rotating separator sheet on an angle grinder can also be used.
Metal saws range from simple, manual hacksaws through to powered horizontal or vertical band saws and circular saws. When looking for a metal saw for sale, it's best to give some thought to the exact nature of the jobs you'll want to use it for and tailor your purchase accordingly. Vertical band saws are particularly useful in cutting curving or unusual shapes. Additionally, there are abrasive saws, otherwise known as metal chop saw, which are conveniently light and portable. These items have found a great deal of favour on building sites and smaller workshops as they can perform jobs previously done chiefly by the use of acetylene torches.
The Structure of a Metal Cutting Saw
Mechanical saws consist of a saw blade, a clamp and a motor. Electric circular saws, bandsaws and hacksaws are stationary machines, which are equipped with their own work table and stop. Thereby, metal cutting saws are set up for a variety of tasks can produce very precise cuts. The preparation of a metal block for further processing on a lathe or milling machine can be undertaken on a stationary saw. Just like all metal cutting machines, electric saws are also equipped with a cooling lubricant. Reciprocating saws are electric hand tools, used to free-handedly separate metal. They are commonly used to recycle automobiles because they can easily be used to cut through the vehicle's beams. Their advantage is that they are free on one side . This means that they can be used for complex materials without any problems. These metal hand saws can be used to process tubes and profiles on-site. Reciprocating saws need to produce very precise cuts. The one-sided open saw blade tends to deflect in a lateral direction, which means that the precision of the cut can only occur within the range of a millimetre.
Types of Metal Saws
Various forms of saws designed for cutting metal are available from used industrial equipment auctions.
- A Hacksaw may be manually operated or powered. Most are hand held saws having a C-shaped frame in which a blade is held under tension. Panel Hack Saws have a sheet metal body and allow for greater control and cutting precision. The Power Hacksaw, otherwise known as an Electric Hacksaw, is powered by its own integral electric motor or may be linked to a stationary engine. This type of saws are not as extensively used in the metalworking industries as they once were, and so can often be picked up at very reasonable prices from used industrial machinery.

- A Horizontal Band Saw is a machine tool using a blade in the form of a continuous metal band with teeth along one edge. Due to an evenly distributed tooth load, these produce a uniform cutting action. Horizontal Band Saws for the cutting of metal are capable of speeds ranging from 12 metres up to 1,500 metres per minute.
- A Vertical Band Saw is particularly handy for the cutting of curved or irregular shapes. Blade cooling systems are common on such equipment and they are also generally fitted with brush wheels to clear debris from between the teeth of the blade.
- A Circular Saw for cutting metal generally uses a cold saw process with large diameter blades and low rotational speeds. Circular saws can be a segmental tooth, solid tooth or carbide inserted tooth and use coolants to prevent overheating caused by friction. Makita makes, apart from other saws and tools, circular saws that have great cutting capabilities.
Applications & Characteristics of Different Types of Metal Sawing Machines
Metal cutting saws are used to cut metal blocks, profiles, pipes, bars and grooved pieces of sheet metal. These are used to cut intermediary stage products to the extent that they are then ready for further processing. Therefore, metal sawing technology is a very important tool for every metalworking workshop. Precise cuts and the production of complex constructions can be ensured with the implementation of additional applications like guides.
Bandsaws have the advantage that they do not heat up. The band creates heat during the sawing process, but this is continually expelled into the surrounding air. A metal band saw is suited for precisely cutting tubes, bars and profiles. Metal band saws only require a short cutting surface and can be set to process specific points.
Automatic hacksaws generally require a cooling agent. They are characterised by their ability to produce very precise cuts and are more suited for long cuts. Hacksaws are particularly suited to cut metal blocks since the saw maintains the same position throughout the cutting process. In most cases, a cooling agent is required to cool the saw blade and the workpiece, and to remove the chippings.
Just like metal cutting saws, circular saws and angle grinders are also used to cut pipes and profiles. Their advantage is that they have very high cutting speeds. They are less suited to cut metal blocks. The height of the saw blade defines the maximum thickness of the block. Metal cutting circular saws often overheat and jam because cooling agents cannot be easily applied.
There are also smaller tools like the metal cutter that can be handled manually that adapt to smaller needs.
Metal Cutting Machine Operation and Safety
Saws are used to prepare intermediary metal workpieces. These workpieces will be further processed at different stations, and so it is highly required that the cut metal workpiece is very precise. However, adjustments are also manageable. Therefore, metal cutting saws can be operated by assistants. A thorough briefing is very important. Clamping in the workpiece correctly, and adjusting the sawing and feed speeds, need to be well understood and practised by the worker. The attention to work safety is very important. Wear eye protection and suitable protective clothing is obligatory. Metal cutting saws are great machines for first learning how to process metal. Just like all cutting machines, these saws create a large amount of dirt and waste. The correct and thorough cleaning and maintenance of these machines needs to be understood by the operator and then reliably undertaken. Normally, this only consists of switching the saw blade. A metal cutting hand saw is constructed in such a way, that this can be very easily undertaken.
However, unskilled assistants should not operate these machines unsupervised. Hacksaws make wide sweeping oscillations and the saw band of a bandsaw can suddenly rip. Both are associated with a high risk of injury. All workers need to be briefed on the risks of injury associated with a metal cutting saws before using these machine.
