China Cheap price 4 Circular Saw Blade 40 Teeth - vacuum brazed blade（circle hole) for steel and iron – UPIN

Main Function
Mainly used for all kinds of metal pipes, thin-walled stainless steel, rebar, Angle steel, aluminum and other metals, HDPE and PVC plastic pipes, metal roofing panels, metal plates, with matching adjustable aperture ring
1.They will cut, shape, grind pretty much any material you care to show it.
2.It’s why vacuum brazed technology is the basis for “Rescue Blades” used by emergency services worldwide.
3.Offered in two sizes as a utility angle grinder blade. Particularly good for cutting for marble and soft friable stones that break out when using traditional blades.
Also extensively used on fibreglass and other similar composites.
4.The cutting action is very smooth, much more like a “filing” action and not at all aggressive like a traditional sintered diamond blade.
5. Whilst these blades will cut hard ceramics and porcelain, there are better blades for those products. It wouldn’t last long and likely would provide a clean cut on dense porcelain.

With the development of National Urbanization Constriction, many problems have to be solved in the engineering construction and emergency rescue area. High efficiency; safety and convenient cutting the high strength steel or steel-composites structure have become the major problem The application practice shows that the traditional electroplated or multi-layer sintering diamond saw blade carbide saw blades and resin grinding wheel exist abrasive fall off or tools fracture in the process of heavy load and high speed machine, which is due to the low bond strength among the abrasive ,the cutting head and the binding agent Therefore , the disadvantage of the above saw trades have seriously affected the processing efficiency safety aid service life.
