M51 - Bimetal Band Saw Blade with 10% Cobalt and 10% Tungsten Designed for use in heavy duty cutting applications. The cutting performance of the high speed steel teeth is greatly increased through alloying with 10% cobalt and 10% tungsten. These alloying elements substantially increase heat resistance as well as fatigue resistance. Longer operating life Increased cutting accuracy Allows cost-efficient cutting of materials with low machinability, such as nickel and titanium alloys [mm] Specifications - M51 teeth per inch (tpi) 1,25 0,75/1,25 1,4/2 2/3 3/4 4/6 [in.] 27 x 0,90 CS 1 1/16x.035 34 x 1,10 CS 1 1/3x.042 41 x 1,30 1 5/8x.050 54 x 1,60 2 1/8x.063 67 x 1,60 80 x 1,60 2 5/8x.063 3 1/8x.063 Matrix 2 The Matrix2 saw band is manufactured with the same 4% chrome backing material as all our other high-quality bimetal band saw blades. The superior properties of the tooth cutting edge during high-vibration sawing, like cutting thin-wall tubing, cross sections and bundle cutting applications, are achieved through reduced tungsten and carbon content. High cobalt content (8%) gives high edge wear resistance. This saw blade, with its excellent cutting edge features, is suitable for cutting medium alloyed steel, as well as non-ferrous metals in an automatic sawing mode.

Band Saw Blade Geometry Several vital geometric measurements used to describe saw blades in the diagrams require definition. Tooth pitch Tooth pitch, which for metal-cutting saw blades is usually measured in teeth per inch, varies according to the cross section and the type of material to be cut. Constant Toothing Variable Toothing Tooth set "Tooth set" means the alternating lateral bending of saw teeth. It enables the saw band to cut freely. Raker set The raker set (left-right-straigth) is useful for all types of steel, especially for cutting thicknesses of 5 mm and more. Variable set In a variable set there is one unset tooth per toothing interval. The rest of the teeth are bent alternately left/right. This set facilitates a low-vibration and a low-noise cutting. Wave set The wave set is well suited for thin materials up to 5 mm, such as sheet metal, thin-walled tubing and cross sections.
Tooth forms ormal tooth The normal tooth is best suited for the sawing of materials with high carbon content, such as tool steel or cast iron with short chips. It is suitable for a wide range of applications, including thin crosscuts and materials with thin-walled cross sections. Zahn Zahn variable Hook tooth The hook tooth with a positive rake angle can be used for all types of steel, especially for long-chip and hard-to-cut materials, for example construction steel and hardened steel, as well as high alloy materials. Zahn CS Zahn CS variable Special hook tooth The special high-performance hook-tooth with modified tooth geometry for high alloy steel with low machinability as well as exotic alloys and for Cr-i-Ti-alloys.

Recommendations for blade use Contour sawing To select the blade best suited for a cutting operation, determine the smallest arc (radius) to be cut and choose the corresponding blade width from the chart; the smaller the arc, the narrower the blade. Eberle metal band saw blades are high quality tools. In order to ensure optimum performance and operating life, it is vital to select the correct blade as well as proper break-in and operating conditions. Blade Tension Before sawing with a new blade one should check the tension of the blade and tighten it after a few cuts if necessary. Eberle duoflex band saws are prestressed to a tension of 250-300 /mm², 36-43 Ksi. Band Saw Guide The accuracy of the cut depends on the setting of the band saw blade guides - the closer to the material the more accurate the cut. When breaking in a new blade only a half of the normal feed pressure/rate and cutting speed should be used until a surface area of 50-150 sq.in. has been cut. The feed rate and cutting speed can then be gradually increased to normal. The form of the chips indicates whether the cutting pressure and cutting conditions are correct: a) Very fine or pulverized chips indicate that the blade feed rate should be increased. b) Thick, heavy or blue-colored chips indicate that the saw blade is being overloaded. c) Loosely coiled chips indicate ideal cutting conditions. Cooling and Lubrication Cooling and lubrication are indispensable in most metal working operations. In the case of aluminum and aluminum alloys the coolant also aids in chip removal and the maintenance of a higher-quality surface finish. o lubrication is necessary for cast iron, brass and some nonmetallic materials such as plastic, graphite, etc..
