A manual metal saw can be differentiated into types depending upon the design, functionality, and application. Each kind of manual metal-cutting saw is made to meet the varying needs of users in the industrial, construction, repair, and manufacturing sectors.
Various metal-cutting instruments are available on the market, and each has its own set of applications. Nonetheless, manual hacksaws' basic characteristics are constant and consistent. The saw blades' basic features include manual metal saw types and sizes and the teeth per inch.
The size of the blade dictates what kind of metal can be cut, as well as the power required to cut it. Larger blades require a greater amount of power to tension them, for example, broader blades are usually used for cutting bigger sections of metal and for straight cutting rather than for making intricate cuts. They are also more suitable for higher-speed saws. Larger blades also produce a more massive chip that requires a higher cutting power.
Common types of blades used in manual metal cutting saws are carbon steel, bimetallic, and high-speed steel. Super high-speed steel may also be used in specific blades requiring particular applications.
The blades process and finish the metal vary in design, such as the teeth shape and the gap between the teeth. The size of the teeth, usually 3 to 24 teeth per inch, determines the smoothness of the finish and the speed at which the material is cut. Blades with fewer teeth, such as 3 to 10 teeth per inch, are typically used for cutting more massive sections of metal, and blades with more teeth, such as 14 to 24 teeth per inch, are typically used for cutting thinner sections. More teeth per inch usually results in a smoother finish and a faster cutting speed. The teeth design also varies and includes straight, wavy, and raked.
Storage is the main aspect of maintenance required by manual saws. To prolong the life of a saw, it should be stored in areas away from moisture and dust. If rust occurs, following up with a rusty blade may improve the situation. Rubbing chalk on the blade before cutting helps to absorb any moisture. Keeping the blade clean and free from debris can help with the cupping and cutting issues.
The life of a manually operated saw can be extended by learning how to cut straight with a manual metal saw, which includes techniques such as lubricating the blade before cutting, marking the material that needs to be cut, and securely clamping the material before cutting. When cutting, pivot the handle slowly and evenly back and forth; this will help the blade to cut on its own without forcing it through the material. Unclamp the material before proceeding to the next cut.
The application scope of manual metal saws for cutting metal is vast and varied. They are proficient in several industries, dealing with various workpieces of different sizes.
When choosing the right manual metal cutting saw, there are a lot of things to keep in mind. First of all, it will be really important to ascertain the kind of tasks the saw will be used for. Will it be used to cut through heavy-duty metal piping/large metal pipes or something a bit less challenging, like aluminum or copper? This will go a long way in ensuring the appropriate saw is chosen.
Consider also the comfort the saw will provide. Based on usage statistics, operator fatigue is a real issue, especially when the metal in question is quite thick. In this case, it will be important to look for a saw with a comfortable handle and a well-balanced design that will help minimize fatigue over prolonged use.
It might be useful to look for additional features as well, like tool-less blade change systems or integrated work clamping systems. Clamping systems will be necessary to hold the material in place while cutting through it instead of having to pass the material through a clamp — which is what applies in some scenarios.
Cutting capacity is another crucial factor when choosing the right manual metal cutter. It is important to note that different metal saws have different cutting capacities. Therefore, it is paramount to choose a saw that can cut to the required depth and width.
Finally, after making a choice, it's important to familiarize oneself with the correct techniques. Take time to read up on various articles, videos, and manuals to understand the best practices when using the chosen manual metal saw. In this way, accurate cuts can be achieved, and material wastage can be minimized.
Q1: How is a manual metal saw different from a hacksaw?
A1: While both metal saws are hand-powered and used to cut metals, the manual metal saw is bigger and heavier than a typical hacksaw. The frame of a manual metal saw is also designed to hold larger blades than those commonly used in a hacksaw.
Q2: Is a manual metal saw used in a workstation more beneficial than buying one for individual use and capacity?
A2: When looking to purchase manual metal saws for use in the machinery industry, it is more beneficial to buy in bulk, as the per-unit price will be significantly lower compared to purchasing individual pieces.
Q3: Can a manual metal saw be used to cut through pipes?
A3: Yes, one of the greatest advantages of considering a manual metal saw for purchase in the B2B machinery industry is its ability to cut through different types of materials, including pipes of various thicknesses and materials.
