Bimetal bandsaw blades cover the broadest range of sawing applications and materials. Bimetal blades, also known as M42 / M51 blades, are cost effective, high performance, and have excellent fatigue life. The high quality industrial and residential saw blade combines the flexibility of a spring steel backer with the wear resistance of an M-42 / M-51 high speed steel tooth. Bimetal material consists of two kinds of metal: The alloyed spring steel creates the body of the band saw blade strip, a high speed steel wire is welded to the top of the body. When teeth are milled into the bimetal strip, the High Speed Steel material creates the tips of the teeth. After heat treatment of the band the tooth tips of bimetal band saw blade become very hard but the body of the blade stays flexible. Such combination of materials ensures the best mechanical characteristics of the tools: wear resistance, high flexibility and cyclic bending resistance. Bimetal bandsaw blades for metal cutting are designed to cut a wide variety of materials including, but not limited to:
> Carbon steel
> Tool steel
> Structural steel
> Stainless steel
> Pipes/tubing
> Die steels
> Angles/flat stock
> Other mixed metal applications
A wide variety of products are available to ensure optimal blade performance in your application

Bi Metal Bandsaw Blades for Metal Cutting

Bimetal refers to an object that is composed of two separate metals joined together. Instead of being a mixture of two or more metals, like alloys, bimetallic objects consist of layers of different metals. Trimetal and tetrametal refer to objects composed of three and four separate metals respectively. A bimetal bar is usually made of brass and iron.

Bimetallic strips and disks, which convert a temperature change into mechanical displacement, are the most recognized bimetallic objects due to their name. However, there are other common bimetallic objects. For example, tin cans consist of steel covered with tin. The tin prevents the can from rusting. To cut costs and prevent people from melting them down for their metal, coins are often composed of a cheap metal covered with a more expensive metal. For example, the United States penny was changed from 95% copper to 95% zinc, with a thin copper plating to retain its appearance. A common type of trimetallic object (before the all-aluminium can) was a tin-plated steel can with an aluminum lid with a pull tab. Making the lid out of aluminum allowed it to be pulled off by hand instead of using a can opener, but these cans proved difficult to recycle owing to their mix of metals.

Blades for bandsaws and reciprocating saws are often made with bimetal construction. The teeth, made of high speed steel, are bonded (by various methods, for example, electron beam welding or laser beam welding) to the high-strength carbon steel base. Such construction makes for blades with a better combination of cutting speed and durability than shown by non-bimetal blades, because the advantages and disadvantages of each of the metals are applied in the best locations: the teeth are harder (and thus cut better), but therefore also brittler; meanwhile, the body area of the band is softer (which would make for poorer teeth), but also less brittle, and thus more resistant to cracking and breaking (which is desirable in the body area). Band saw blades come in a variety of widths, tooth design, materials, and configurations.

A bandsaw (also written band saw) is a saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw.[1] The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches (teeth per inch, or TPI), which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic.

Gujarat Industrial Development Corporation (GIDC) was established under the Gujarat Industrial Development Act of 1962, with a goal of accelerating industrialization in the state of Gujarat, India. GIDC is now establishing Special Investment Regions, PCPIR, Industrial areas and large /sector-specific estates in tune with the changing economic and industrial scenario. The Government of Gujarat enacted the SIR act in 2009 with the objective of creating large size Investment Regions and Industrial Areas in the State of Gujarat and develop them as global hubs of economic activity supported by world class Infrastructure. Gujarat is the only state in the country to enact such an Art.

Makarpura is a major area in Vadodara city of the Gujarat state in India. It is an important industrial area of Vadodara city having Gujarat Industrial and Development corporation (G.I.D.C),which comprises many important and large Multinational corporations like Siemens, ALSTOM, ABB Group, TBEA, Philips, Panasonic, FAG, Sterling Biotech, Sun Pharmaceuticals, L&T, Schneider and ALSTOM Grid, Bombardier, and GAGL (Gujarat Automotive Gears Limited). There are also a number of glass manufacturing companies in and around Vadodara, including Haldyn Glass, HNG Float Glass and PiramalGlass.Vadodara Chamber of Commerce and Industry is also situated in Makarpura.

The Makarpura Palace is a former Gaekwad royal palace in this locality. It was built by Maharaja Khande Rao in 1870, designed in the Italian style. It was extended and renovated by Maharaja Sayajirao Gaekwad III. The palace is now used as a training school called No.17 Tetra School by the Indian Air Force.Makarpura area is also an important area of Vadodara city in terms of transportation as it has a railway station and a bus station.
