Metal Cutting Bandsaw Blades

To get the best possible performance out of your metal cutting bandsaw blades you want to have an optimal selection available to you. This will also provide longevity out of your blades and avoids damage to your machines and your material. There are some factors to consider when choosing the right blades for your projects such as pattern, pitch, and blade material. Let’s look at some of these things in relation to metal cutting, specifically.

Bandsaw blades have teeth and these teeth are slightly wider than the blade body. This helps to ensure your cuts will be wide enough to prevent your blade from getting stuck in your cutting material. While a pattern like a raker pattern may be used for ordinary jobs, a wave pattern may be used for thinner cutting such as hollow tubing or angle sections.

The pitch of your blade is its TPI (teeth per inch) but can also sometimes be measured in metric as teeth per 25 millimeters. If you are looking for a fine versus rougher finish you would want a finer blade, meaning a blade with more teeth per inch. Things that can also improve the finish are faster cutting speeds and lubrication. You will need a high TPI for thinner cuts meaning at least three teeth are making contact with the material along the width of it at all times. If you are cutting thicker material, however, this would require a lower TPI and a slower cutting speed.

The harder the blade the harder material it will cut but at a slower speed. If you use the wrong blade for the material you’re working with or if you are cutting too quickly for the blade pitch or the material you can cause excessive wear too quickly resulting in replacing your blade earlier than you should be. There are three main types of metal cutting bandsaw blades which are high-speed steel, carbon steel, and alloy steel. Carbon steel can cut softer metals and alloy steel can cut a few of the harder materials. High-speed steel blades can cut even stainless steel. Paying attention to the pitch and pattern of the teeth and what material the blade is made of is the best way to choose the best blade for your project.
