When cutting metal, the choice of the saw blade is very important for clean and accurate cuts, as well as for the longevity of the blade itself. The perfect saw blade to cut through metal varies depending on different factors, including the type of metal, thickness of the material, and specific cutting needs. This write-up will give you an in-depth look at different types of saw blades that work well with cutting metal plus their features and where best to use which.
High-Speed Steel (HSS) blades are quite popular when it comes to cutting metal because they are sharp and affordable. HSS blades are composed of steel and other elements like tungsten, molybdenum, and chromium with adequate levels of hardness and heat resistance. Blades of this kind are perfect for cutting aluminum and brass, non-ferrous metals, and mild steel. On the negative side, they get to wear out fast when applied on harder or abrasive materials. 2. Carbide-Tipped Blades Carbtde-tipped blades gain recognition for their long life span and capability to cut through sturdy materials. These blades have carbide teeth — carbide is a compound of carbon and tungsten that is very hard and resistant to wear. Cermet-tipped blades can be used to cut a broad spectrum of metals from stainless steel, carbon steel & alloys; they outlast HSS blades and leave cleaner cuts with less burr formation. They are commonly found in industrial environments where large volumes need to be cut. cermet-tipped blades - till recently an innovation in cutting technology Cermet tipped saw blades are ideal for mild and stainless steel cutting applications. Cermet is a combination of ceramic and metallic materials that offer good heat resistance and wear properties. Originally developed for woodcutting, these blades will handle general metal-cutting quite well Cermet-tipped blades maintain their sharp edge longer than other carbide-tipped blades, but are also more brittle. Blades normally come with a variable pitch tooth pattern that will help reduce vibration when cutting. This type of blade is designed to house a tungsten carbide tooth tip that we have induction brazed on to ensure minimal body damage upon return for repeat orders as expected from those in the repair industry. Bi-metal blades are used in band saws and reciprocating saws for industrial and do-it-yourself applications. 5. Diamond Blades Diamond blades are used for cutting very hard or highly abrasive materials. While most commonly thought of in terms of cutting concrete or masonry, diamond blades can also cut some types of metal; they excel at it when a high level of precision and smooth cuts are needed. These blades have diamond particles bonded to the edge for increased strength and cutting performance. An example of where these specialized blades excel would be cutting metal pipes along with other tasks involving hard materials. Factors that Affect the Selection of Saw Blade for Metal Cutting 1. The Metal! For softer metals like aluminum and brass, HSS blades may be fine. For harder metals like stainless steel and alloys, carbide-tipped or cermet-tipped blades are more appropriate because of the higher levels of durability and cutting performance.
The choice of saw blade is also influenced by how thick the material is that is to be cut. Thicker materials need low TPI blades to allow for efficient chip removal (and prevent clogging) while thinner materials can be cut with high TPI blades for smoother and more precise cuts.
Blades need to work hand in hand with cutting speed and feed rate especially in industrial settings where time is a critical factor. Blades designed for high-speed cutting can handle faster cutting speeds and higher feed rates improving productivity in the long run by reducing cutting time as well.
While the initial cost of blades is important, the longevity of the blade should be considered. At times, carbide-tipped or cermet-tipped blades may have a higher front-end value, but they will offer better overall value because of longer life — reducing replacement frequency and associated downtime costs. 5. Specific Cutting Requirements The type of specific cuts to be made will also influence blade choice regarding what is ideal. Separation perfection-related applications that require high levels of precisions and smooth finishes might need diamond blades. On the other hand, bi-metal blades suit general-purpose cutting applications well while providing flexibility and durability. Conclusion Several factors come into play when trying to select the best saw blade for cutting metal. These include the type of metal being cut, material thickness, cutting speed — in addition to blade longevity and specific cutting requirements. High-Speed Steel (HSS) blades can be used with softer metals and non-abrasive materials. Although HSS is the most common material cut by staple manufacturers, carbide-tipped and cermet-tipped blades provide increased strength and performance in cutting more robust metals. Bi-metal blades offer users a combination of versatility and maneuverability across many cutting applications while diamond blades are perfect for particular jobs that need very smooth and precise cuts because they work well on irregular surfaces.
Understanding the different types of available saw blades and what each is used for allows you to choose how best to achieve great cutting performance during metalworking projects, as well as opportune efficiency gains.
