Metal cutting saw blades are designed to cut through metal quickly with finished, burr-free results, allowing you to minimize work-time while maximizing efficiency. There are several types of metal saw blades produced on the market today. Each can handle the high strength of metal while providing a long blade life, reducing the need for frequent blade changing.

Metal cutting saw blades can usually be found in two forms. The first is made from either metal, such as stainless steel, chrome vanadium steel, or aluminum oxide. The second is made from an abrasive material designed to slice through metal.

Metal-Bodied Blades

Metal body blades are constructed from high-strength alloys such as stainless steel, aluminum oxide, or vanadium steel. They are typically coated with a composite material (such as tungsten carbide) or a ceramic-metal composite, enabling them to withstand the high heat generated by cutting through metal. The composite material also ensures clean cuts and long blade life. The blades are then heat-treated at high temperatures to reduce heat build-up and prevent excessive sparking.

These metal body blades have smaller and more teeth than their wood-cutting counterparts. These fine teeth generally range from around 30 per blade up to around 100. They allow the blade to make quick, shallow cuts that prevent burrs and excessive chipping while quickly slicing through metal.

Abrasive Discs

Abrasive metal cutting blades are made from rough and insulating materials designed to withstand the demands of cutting through metal while producing clean, precise cuts. Most contain an aluminum oxide grain that’s reinforced with two sheets of fiberglass or another insulating material. This combination allows for the rough, abrasive blade to withstand high velocity and resist metal, enabling it to produce clean, burr-free cuts in virtually all metals.

Conclusion

While there are differences in what materials make up a metal cutting saw blade, they both perform the job of cutting through metal cleanly and easily. Both abrasive discs and metal-bodied blades allow high-powered metal cutting saws to achieve high-quality, precise results with minimal effort on the user.
