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 Band saw Blades
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.
Carbon saw blades are an economical choice and used to cut different types of non-ferrous materials. This type of blade cuts soft materials like wood, plastics, and brass. Also low-alloy and mild steels. Carbon blades used at the correct speed, can cut Stainless Steel using a coolant.
Bi-Metal saw blades cost more than carbon blades but last longer depending on the types of materials being cut.
Correct band speed and feed rates can be determined by examination of the chips produced during the cutting process. The chips should be curled and warm, not hot. Stainless steel chips are short curls with a yellow wheat color. If not, then too much heat is being generated. Extreme heat will produce blue chips and result in premature saw blade failure. Reduce the speed and feed rates in order to help normalize the cutting process.
Keep an eye on the type of chips while using different types of blades while working on various materials. This can help one choose between Carbon Steel & Bimetal bandsaw blade
How to Choose TPI for Bimetal Bandsaw Blades
Teeth Per Inch (TPI) selection is arguably the most important decision when selecting a band saw blade. If the correct TPI is not chosen the blade life will be dramatically reduced.
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. Almost all bandsaw machines today are powered by an electric motor. Blades with more teeth cut slower and smoother. Blades with fewer teeth cut faster, with slightly rougher finish. For any kind of precision cutting, the rule of thumb is to always try to keep at least three teeth in the material at all times. This adds stability and accuracy.
Difference between Constant TPI vs Variable TPI for bimetal band saw blade cutting
Constant TPI is more advisable for soft materials like Aluminium, Copper, etc. A constant-pitch saw blade can increase harmonic vibrations. Harmonic vibrations can lead to excessive noise, undesirable saw or saw blade vibrations, and in severe cases, a bad cut. Hence for harder materials, it is recommended to choose amongst variable TPI. This includes Steel of various categories.
Hook tooth blades have a deeper gullet—that is, larger teeth—and a positive 10 degree rake angle. This helps the blade to feed into the material more aggressively. The result is faster cutting rates. Hook tooth blades are more suitable for soft materials like MS steel. Harder materials need smoother teeth profile or straight tooth profile.
A raker tooth set has one tooth going to the left, one to the right, followed by a straight, or unset, tooth, which is called a raker. The raker set (left-right-straight) is useful for all types of steel, especially for cutting thicknesses of 5mm and more.
An alternate tooth set has one tooth going left, one going right, then left, right, etc. There is no raker tooth. The double alternate plus raker has an unset raker tooth following two left-right combinations. 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 low-vibration and low-noise cutting.
A wavy tooth set has groups of teeth set left and right, separated by unset raker teeth. Wavy set blades are made primarily with the small teeth recommended for cutting thinner metal sections, tubes, pipes, thin sheets, etc. The wave set is well suited for thin materials up to 5mm, such as sheet metal, thin-walled tubing and cross sections.
Substances of big diameters must be cut with band saw blades with coarse toothing. For workpieces with small diameter or for profiles, blades with finer enamel pitch must be used.
A minimum two to three teeth should be inside the cut on the identical time.
The smaller is the quantity of teeth in the cut, the higher is the cutting performance (due to the fact the stress distribution on much less tooth means higher ability for the tooth to get into the material).
For gentle materials (as as an instance aluminium or bronze) a smaller TPI ought to be selected, due to the fact those materials need greater area among the teeth for eliminating the chips. in any other case the chip it might cumulate around the tool and will negatively affect the quality of the cut surface.
Correct toothing = optimal performance
Thumb rule while selecting bimetal bandsaw blades related TPI for metal cutting
Different types of chips while cutting metal using bandsaw blades describes the optimum cutting conditions :: Speed & Feed
Feed refers to the depth of penetration of the tooth into the material being cut. For cost effective cutting, you want to remove as much material as possible as quickly as possible by using as high a feed rate/pressure as the machine can handle. However, feed will be limited by the machinability of the material being cut and blade life expectancy. A deeper feed results in a lower shear plane angle. Cutting may be faster, but blade life will be reduced dramatically. Light feed will increase the shear plane angle, but increase cost per cut.
Very fine or pulverized chips indicate that cutting pressure is too low.
Thick, heavy or bluish chips signal overstressing of the saw blade.
Loosely coiled chips are a sign of ideal cutting conditions.
Gullet capacity is another factor that impacts cutting efficiency. The gullet is the space between the tooth tip and the inner surface of the blade. As the tooth scrapes away the material during a cut, the chip curls up into this area. A blade with the proper clearance for the cut allows the chip to curl up uniformly and fall away from the gullet. If too much material is scraped away, the chip will jam into the gullet area causing increased resistance. This loads down the machine, wastes energy and can cause damage to the blade.
How do you know if you are using the right band speed? Look at the chips; check their shape and color. The goal is to achieve chips that are thin, tightly curled and warm to the touch. If the chips have changed from silver to golden brown, you are forcing the cut and generating too much heat. Blue chips indicate extreme heat which will shorten blade life. Too high a band speed or very hard metals produce excessive heat, resulting in reduced blade life.
Lubrication is essential for long blade life and economical cutting. Properly applied to the shear zone, lubricant substantially reduces heat and produces good chip flow up the face of the tooth. Without lubrication, excessive friction can produce heat high enough to weld the chip to the tooth. This slows down the cutting action, requires more energy to shear the material and can cause tooth chipping or stripping which can destroy the blade. Heat is the primary enemy of any tool cutting edge. Excessive heat generated during chip formation can cause the cutting edge to wear rapidly.
Bandsaw Blades Break in to maximize life of the bimetal band saw blades
A new band saw blade for metal cutting for all make & size has razor sharp tooth tips. so as to face up to the cutting pressures employed in band sawing, tooth tips ought to be honed to create a micro-fine radius. Failure to perform this honing can cause microscopic harm to the ideas of the teeth, leading to reduced blade life.
Why break-in a Band Saw Blade while cutting metal?
Completing a correct break-in on a brand new band saw blade can dramatically increase its life.
Thumb Rule for proper break-in a Band Saw Blade for metal cutting?
Select the right band speed for the material to be cut
Reduce the feed force/rate to realize a cutting rate 20% to 50% of normal (soft materials need a bigger feed rate reduction than tougher materials).
Begin the primary cut at the reduced rate. make certain the teeth area unit forming a chip.
Tiny changes to the band speed is also created within the event of excessive noise/vibration.
During the primary cut, increase feed rate/force slightly once the blade totally enters the piece of work.
With every following cut, step by step increase feed rate/force till traditional cutting rate is reached.
Selecting M42 vs M51 Bi Metal Band saw Blades for metal cutting
The high quality Bi-Metal band saw blades combines the flexibility of the spring steel backing with the enormous wear resistance of high speed steel. Each tooth tip of the finished band is of hardened HSSsteel, extremely durable for best performance. M51 has approximately 69 HRC while M42 has approximately 67 HRC hardness. M51 can perform better for hard material while M42 is more advisable for soft material, though both can be used interchangeably
How to choose the teeth per inch for Bi metal bandsaw blades for metal cutting
The number of teeth on the blade helps determine the speed, type and finish of the cut. Blades with fewer teeth cut faster, but those with more teeth create a finer finish. Gullets between the teeth remove chips from the work pieces. The chips decide the efficiency of the cut. For maximum cutting efficiency and lowest cost per cut, it is important to select a blade with the right number of teeth per inch (TPI) for the material you are cutting. Following diagrams might help you choose the right set of teeth for various materials. This is generally true for all makes of bimetal band saw blades for metal cutting.
Troubleshooting parameters of bandsaw for proper cutting while using bi metal band saw blades for metal cutting
There are several factors that affect band sawing efficiency: tooth design, band speed, feed rates, vise loading, lubrication, the capacity and condition of the machine, and the material you are cutting. Always try to keep these points in consideration while using bi metal bandsaw blades for metal cutting.
Pls follow the following guidelines while cutting the metal using the bandsaw blades:-
1. Never run the machine faster than the recommended speed for the specific material
2. Make sure the workpiece is flat on the table before starting the cut.
3. Do not start cutting until the blade has attained its full speed.
4. Never make adjustments until the machine has fully stopped.
5. Remove excess chips using brushes or rags after stopping the machine in order to prevent large quantities of chips from accumulating.
