Bimetal bandsaw blades

For heavy production metal shops, bimetal bandsaw blades are essential. Strong blades that are designed for cutting through heavy walled metal, they make short work of both solid blocks and pipes.

Just this one type of blade can be used for carbon steels, alloy steels, stainless steels, and various other metals. You can cut single pieces, bundles, and stacks. It will get you through structural steel, steel tubing, I-beams, and girders.

High quality bimetal bandsaw blades reduce vibration and noise, which means lower heat generation and less probability of the blade breaking under tension. If the blade and material being cut are appropriately cooled during the cutting process, it should result in a nice clean cut without undue wear and tear on either the blade or the material.

It’s important to use the right blades

Sometimes you may see it suggested that a “wood cutting” bandsaw can be used for cutting metals. While it’s not exactly a recommendation, there is some truth to this, as the blade is the real determining factor of what you can cut.

Even so, there may be some other differences such as the power of the motor and the speed of the revolutions, and even the degree of control precision that can make one type of machine more suited to a specific material. Wood blades, being made from steel, can actually cut through soft sheet metal (e.g. aluminium), but there isn’t really any benefit to doing that, it’s dangerous, and it’s uneconomical due to the wear on the blade.

Wood blades have the teeth spaced too far apart to make them suitable for cutting metals, and the blade strength is likely to be much lower than the strength of a blade specifically designed for metalwork. Attempting to cut thick metal with a blade designed for wood could be very dangerous and is likely to damage the machine, the material, the operator, and bystanders. So for all these reasons, we strongly urge you not to attempt such an experiment.

Metal cutting blades have finely spaced teeth, and there are more teeth along the length of the blade. The blade itself is sure to be stronger and made from a very hard combination of metals to ensure it is long lasting and safe.

Once you ensured you have the correct blade, you also need to ensure it’s properly tensioned. Too much tension and the blade is likely to snap or overheat, too little tension and it is likely to vibrate excessively and jam. If the blade jams, it can damage the motor, but this to some extent also depends on the safeguards built into the machine. Some machines are capable of detecting when a jam occurs and may disengage the motor until the problem is fixed. Even if this is the case with your machine, you should always shut off the machine completely before attempting any kind of maintenance work on it.

During the cut, if you’re working with a strong and thick material such as an I-beam, you’ll need to keep the blade and metal cool. Overheating is also dangerous to the machine, the blade, and the material you are cutting.

Bimetal blades come in various grades, and you should select the best and strongest blades for the kind of work you are doing.
