Blade Thickness

The blade thickness is generally determined by the blade width and the wider the blade, then the thicker the material that it’s made from.  

If your bandsaw is a small 3 wheeled one, then you have to use hobby/thin gauge material which are made from .014” thick material. This material is required as it’s the only material that has enough flexibility to fit around the 3 wheels. Larger 3 wheeled bandsaws can also use SuperTuff Premium blades.

The SuperTuff Premium and Fastcut blades are made from thinner material than standard blades and the main advantage of this is that a wider blade can be run on machines that usually struggle to run a wide blade. There’s also less waste and the blade is capable of running with more tension, which makes it a lot easier getting nice straight cuts.
Another advantage of increasing the tension is that it improves the beam strength of the blade, which again makes straight cutting and setting up the bandsaw a lot easier.

M42 blades require more tension than other blades and not all machines will be able to tension a wide M42 blade sufficiently for it to run correctly. The 1/4", 3/8” and 1/2" M42 blades on sale on the web site are .025” thick so will run fine on most machines and when tensioning them it’s advised to add more tension than normal to get the best from the blade. For example a 1/4" M42 blade should be tensioned to the same amount as a standard 3/8”.
