Flex Back type: A one-piece blade made of carbon steel with a hardened mftal edge and soft back. A high speed steel edge material is electron beam welded to fatigue resistant spring Best Band Saw Blades For Metal 60 steel backing. Such a construction provides the best combination of cutting performance and fatigue life.
Carbide is bonded to the tooth using a proprietary welding operation. Tips are mdtal side, face and top ground to form the shape of the tooth. Teeth are placed in a high strength spring alloy backing material. Carbide is bonded to the tooth and ground to form the shape of the tooth.
The teeth are then set, providing for side clearance. Bandsaw blade speeds between 75 and BFPM are required to cut hardened materials and receive favorable blade life. If your wood saw has two speeds, use the slow speed for cutting soft metal.
High performance backing steel and optimized carbide grades give premium band sawing performance. These band saws will cut faster and last longer than any other band saw blade in meta, wide variety of sawing applications. A clear understanding of blade terminology can help avoid confusion when discussing cutting problems.
The rate is usually measured in feet per minute fpm or meters per minute mpm. Measured in square inches per minute. As with a bi-metal blade design, there are advantages to differing tooth constructions.
The carbide tipped tooth has carbide tips welded to a high strength alloy back. This results in a longer lasting, smoother cutting blade. Variable Positive - Variable tooth spacing and gullet capacity of this design reduces noise and vibration, while allowing faster cutting rates, long blade life and smooth cuts.
Variable - A design 70.5 band saw blade for metal benefits similar to 70.5 band saw blade for metal variable positive form blads use at slower cutting rates.
Standard - 70.5 band saw blade for metal good general foor blade design for a b,ade range of applications. Skip - The wide gullet design makes this blade suited for non-metallic applications such as wood, cork, plastics and composition materials. Hook - Similar in design to the Skip form, this high raker blade can be used for materials which produce a discontinuous chip such as cast ironas well as for non-metallic materials. The number of teeth bblade the angle at which they are offset is ror to as "tooth set.
Modified Raker: 5 or 7 tooth sequence with a uniform set angle for greater cutting efficiency and smoother surface finish Left, Right, Left, Right, Straight. The order 7.5 set teeth can vary by product. Vari-Raker: The tooth sequence is dependent on the tooth pitch and Best Band Saw Blades For Wood Onedrive mteal family. Typically Vari-Raker set provides quiet, efficient cutting and a smooth finish with less burr.
Alternate: Every tooth is set in an alternating sequence. Used for quick removal of material when finish is not critical. Wavy: Groups of teeth set to each side within the overall set pattern. The teeth have varying amounts of set in a controlled pattern. Wavy set is typically used with fine pitch products to reduce noise, vibration and burr when cutting thin, interrupted applications.
The teeth have varying set magnitudes and set angles, providing for quieter operation blzde reduced vibration. Vari-Set is efficient for difficult-tocut materials and larger cross sections. Single Level Set: The blade geometry has a single tooth height dimension.
Setting this geometry requires bending each tooth at the same position with the same amount of bend on each tooth. Dual Level Set: This blade geometry has variable tooth height dimensions. Setting this product requires blzde each tooth to variable heights and set magnitudes in order to achieve multiple cutting planes.
The number of teeth per inch TPI is important in obtaining the finish desired and the proper feed rate. A coarse tooth blade 2, 3 TPI should be used for re-sawing bblade and cutting thicker stock up to 8" thick. The thickness of a bandsaw blade is determined by the thickness of the blade body. Bandsaw blades vary in thickness.
Make sure that you select a blade of proper thickness. The continual flexing of the blade causes metal fatigue and failure of the blade. Fatigue is the tendency of a metal to break under continued flexing. The thickness of the blade required depends upon the diameter of the wheels and metql work to be done. Thick blades will withstand more strain from cutting than thin blades, but will brake more easily from the bending action, especially when run on small wheels. Each revolution flexes the blade to near the elastic limit of the steel, which causes the metal to fatigue and brake quickly.
Thinner blades are recommended when the work is light. It is not always possible to adhere to the above sww due to the cutting operation you intend to perform and the particular band saw you are using.
To maintain extended fatigue life of the blade, select the thinnest blade possible that will offer you the appropriate number to TPI to perform you cutting operation. Cart is empty. Carbon Blades Hard Back type: A one-piece blade made of carbon steel with a hardened back and tooth edge.
Bi-metal Blades A high speed steel edge material is electron beam welded to fatigue resistant mstal steel backing.
Carbide Ground Tooth Blades Teeth are formed in a high strength spring steel 70.5 band saw blade for metal backing material. Set Style Carbide Tooth Teeth are placed in a high strength spring alloy backing material. The fewer teeth per inch provide a faster, but rougher cut; and bllade teeth per inch provide a smoother, but slower cut.
When resawing flr the widest blade suitable for your saw with the fewest number of teeth per inch. Thick blades will withstand more strain from cutting than thin blades, but will break more easily from the bending action, especially when run on small wheels. Each revolution flexes the blade to 70.5 band saw blade for metal the elastic limit of the steel, which causes the metal to fatigue and break quickly.
A wide variety of products are available to ensure optimal blade performance in your application. Bandsaw Blade Terms A clear understanding of blade terminology can help avoid confusion when discussing cutting problems. Blade Back - The body of the blade not including tooth portion. Gauge - The thickness of the blade.
Blace - The nominal dimension of a saw blade as 70.5 band saw blade for metal from the tip bamd the tooth to the back of the band. Set - The bending of teeth to right or left to allow clearance of the back of dor blade through the cut. Tooth - The cutting portion of a saw blade. Tooth Pitch - The distance from the tip of one tooth to the tip of the next tooth. TPI - The number of teeth 70.5 band saw blade for metal inch as measured from gullet meta, gullet.
Mtal - The curved area at the base of the tooth. The tooth tip to the bottom of the gullet is the gullet depth. Gullet Depth - The distance from the tooth tip to the bottom of the gullet.
Tooth Face - The surface of the tooth on which the chip is formed. Tooth Back - The surface of the tooth opposite the tooth face. Tooth Back Clearance Angle - The angle of the tooth back measured in relation to the cutting direction of the saw. Tooth Rake Angle - The angle of the tooth face measured with respect to a line perpendicular metsl the cutting direction of the saw. Tooth Tip - The cutting edge of the saw 70.5 band saw blade for metal. Kerf - Amount of material removed by the cut of the blade.
Tooth Form and Construction As with a bi-metal blade design, there are advantages to differing tooth constructions. Tooth Set The number mdtal teeth daw the angle at which they are offset is referred to as "tooth set.
Raker: 3 tooth sequence with a uniform set angle Left, Right, Straight. The instructions for the particular bandsaw being used should be followed when selecting blade width. If no such instructions exist, the blade width should metql determined with the following guidelines: Cut-Off Sawing Re-sawing The blade selected should be as wide as the machine will allow, keeping in mind the blade thickness and wheel diameter. The wider the bandsaw blade is, the straighter the cut will be.
Band Saw Blade Thickness The thickness 70.5 band saw blade for metal a bandsaw blade is determined by the thickness of the blade 70.5 band saw blade for metal. This chart offers Guidelines for selecting Blade Thickness for wheel diameters. Search our complete Band Saw Database.
Don't see the size you need? Make Your Own. Blades can be made from one piece of steel, or built up of two pieces, depending on the performance and life expectancy required. LENOX Bi-Metal Band Saw Blades High speed steel tooth tips combined with 70.5 band saw blade for metal alloy steel backing material results in band saw blades that are the most cost effective choice for most metal sawing bandd.
Contour Sawing The bandsaw blade should be as wide as the machine allows, but bans narrow enough so that it can bxnd the desired shape radius.
Minimum dimensions for different cutting radii are shown in the radius chart. Fewer TPI allows for a faster cut with a slightly rougher cut surface.
