Metal Bandsaw Blade Guide
Choosing the right metal band saw and corresponding blades is critical to the profitability and efficiency of a production plant or workshop. Failure to do so can lead to shortened blade life or complete blade failure, reducing performance potential. That is why we have created a useful guide that can help break the terminology of blade selection, as well as provide tips on how to extend the life of the metal band saw blades and how to properly break into a new blade. Whether you are sawing large items or difficult-to-cut materials, knowing your blade can make change on your profit.Circular saws: For use with miter saws, table saws, radial frame saws, cutting saws and standard circular saws, they are made of various materials that can cut metal, wood, cement, glass or laminates.
Carbide band saw blades: Designed for cutting composites, metal and wood. High performance steel and optimized carbide grades cut faster and longer in a wide range of applications.
Bimetallic band saw blades: Bimetallic or Bi metal band saw blades are one of the most versatile applications in most metal sawing applications using a wide range of materials such as aluminum and non-ferrous metals, carbon and structural steel. These bi metal band saw blades are cost-effective, work well and have a long blade life due to the fast tooth tips and flexible alloy steel back.
Carbon saw blades: Compare with metal band saw blades, the economical and reliable carbon saw blades are much more ideal for general and useful cutting. They are used for cutting various materials, from carbon steel and aluminum to abrasive materials such as wood and fiberglass, and deal for small maintenance workshops and light production.
Reciprocating saws: Whether it is tiles, clay, wood, cast iron, bricks or metals, reciprocating saws are needed for work. Reciprocating saws are versatile because you can exchange different blades for different materials. And they are Ideal for maintenance, demonstration or repair.
Cold saw blades: Metal band saw blades for pipes, pipes and other hard steel materials are often used for cold cutting steel. Many types of cold saw blades can be re-sharpened and used several times before being replaced. The name comes from the transfer of thermal energy during the cutting process. The blade and working material remain cold, and heat is removed from the system.
Sandblasting blades: Carbide sandblasting saws ensure trouble-free cutting of abrasive and hardened materials, fiberglass, radial tires with steel belts and other composites.
Hole saws: Hole saws cut clean and accurate holes in a variety of metal, wood or plastic materials.
Ring milling cutters: Similar to hole saw, but work in a magnetic drill.
Understanding part of the saw blade
Gullet is the space between each tooth of the saw that allows effective chip removal. The larger the material or the higher the feed speed, the deeper the esophagus (for example in a 2/3 tooth tooth that has a much larger esophagus than the 8/12 tooth esophagus) and the more chips are expelled.
The tooth design is another key part of how metal bandsaw blades are made. Different tooth designs have different advantages. For example, a cemented carbide tooth provides a longer and smoother cutting blade.
The tooth form refers to the shape of the tooth. The shape affects the way the blade cuts through the material, and can extend its life, control the noise level, and provide smoother cutting and chip efficiency.
The changeable positive shape offers variable tooth spacing and esophageal capacity, which reduces noise and vibration while allowing faster cutting, longer blade life and smoother cutting.
The variable shape is similar to the Positive variable, but can be used for slower cutting speeds.
The standard is a good, universal shape that can be used in many different applications.
The Skip shape has a wide clearance ideal for non-metallic applications.
The hook shape is similar to Skip, but can be used in metal and non-metal applications.
The set of teeth refers to the number of teeth and the angle of their shift. Different tooth sets affect cutting performance and chip transfer ability.
Kerf width is the width of the cut made by the blade for the desired material. Full-cut incisions remove about 1/8 "of material, while thin incisions usually remove about 3/32" of material. Because a full cut removes more material, it is best to use it with a stronger saw. Thin cut blades can be used with lower power saws.
Other consumables that may help or hinder cutting conditions are the choice of hydraulic oil and cutting fluids. But it always comes down to choosing a metal band saw blade. Choosing a better crafted blade designed for use results in better wear and heat resistance, fewer replacements, better accuracy and less waste.
To avoid blade failure and make the most of your new shield, remember the following hacking tips:
● Choose the right belt speed for the material being cut.
● Set the feed band feed speed to 50% of normal / recommended feed speed.
● Start the first cut, and after cutting 50-70% of the material gradually increase the feed speed to normal. If vibration / noise occurs, adjust the cutting speed.
